Purpose: Modifications to surgical technique, particularly the widespread adoption of robotic surgery, have been proposed to improve functional recovery after prostate cancer surgery. However, rigorous comparison of men in historical vs contemporary practice to evaluate the cumulative effect of these changes on urinary and sexual function after radical prostatectomy is lacking., Materials and Methods: We compared prospectively collected patient-reported urinary and sexual function from historical (PROSTQA [Prostate Cancer Outcomes and Satisfaction With Treatment Quality Assessment study], n=235) and contemporary (MUSIC-PRO [Michigan Urological Surgery Improvement Collaborative Patient Reported Outcome] registry, n=1,215) cohorts at the University of Michigan to understand whether modern techniques have resulted in functional improvements for men undergoing prostate cancer surgery., Results: We found significant differences in baseline function, with better urinary (median [IQR]; 100 [93.8-100] vs 93.8 [85.5-100], P < .001) and sexual scores (median [IQR]; 83.3 [66.7-100] vs 74.4 [44.2-87.5], P < .001) prior to treatment in PROSTQA compared to MUSIC-PRO patients, respectively. There was no statistically significant difference in the pattern of urinary incontinence recovery after surgery from 6-24 months between groups ( P = .14). However, men in the contemporary MUSIC-PRO group did have significantly better recovery of sexual function compared to men in the historical PROSTQA group ( P < .0001). Further, we found that contemporary practice consists of men with more unfavorable demographic and clinical characteristics compared to historical practice., Conclusions: Our results demonstrate that the widespread alterations in prostate cancer surgery over the past 2 decades have yielded improvements in sexual, but not urinary, function recovery.

Purpose: The summary presented herein covers recommendations on the early detection of prostate cancer and provides a framework to facilitate clinical decision-making in the implementation of prostate cancer screening, biopsy, and follow-up. This is Part II of a two-part series focusing on initial and repeat biopsies, and biopsy technique. Please refer to Part I for discussion of initial prostate cancer screening recommendations., Materials and Methods: The systematic review utilized to inform this guideline was conducted by an independent methodological consultant. The systematic review was based on searches in Ovid MEDLINE and Embase and Cochrane Database of Systematic Reviews (January 1, 2000-November 21, 2022). Searches were supplemented by reviewing reference lists of relevant articles., Results: The Early Detection of Prostate Cancer Panel developed evidence- and consensus-based guideline statements to provide guidance in prostate cancer screening, initial and repeat biopsies, and biopsy technique., Conclusions: The evaluation of prostate cancer risk should be focused on the detection of clinically significant prostate cancer (Grade Group 2 or higher [GG2+]). The use of laboratory biomarkers, prostate MRI, and biopsy techniques described herein may improve detection and safety when a prostate biopsy is deemed necessary following prostate cancer screening.

Purpose: Our goal was to evaluate the comparative effectiveness of robot-assisted laparoscopic prostatectomy (RALP) and open radical prostatectomy (ORP) in a multicenter study., Materials and Methods: We evaluated men with localized prostate cancer at 11 high-volume academic medical centers in the United States from the PROST-QA (2003-2006) and the PROST-QA/RP2 cohorts (2010-2013) with a pre-specified goal of comparing RALP (549) and ORP (545). We measured longitudinal patient-reported health-related quality of life (HRQOL) at pre-treatment and at 2, 6, 12, and 24 months, and pathological and perioperative outcomes/complications., Results: Demographics, cancer characteristics, and margin status were similar between surgical approaches. ORP subjects were more likely to undergo lymphadenectomy (89% vs 47%; p <0.01) and nerve sparing (94% vs 89%; p <0.01). RALP vs ORP subjects experienced less mean intraoperative blood loss (192 vs 805 mL; p <0.01), shorter mean hospital stay (1.6 vs 2.1 days; p <0.01), and fewer blood transfusions (1% vs 4%; p <0.01), wound infections (2% vs 4%; p=0.02), other infections (1% vs 4%; p <0.01), deep venous thromboses (0.5% vs 2%; p=0.04), and bladder neck contractures requiring dilation (1.6% vs 8.3%; p <0.01). RALP subjects reported less pain (p=0.04), less activity interference (p <0.01) and higher incision satisfaction (p <0.01). Surgical approach (RALP vs ORP) was not a significant predictor of longitudinal HRQOL change in any HRQOL domain., Conclusions: In high-volume academic centers, RALP and ORP patients may expect similar long-term HRQOL outcomes. Overall, RALP patients have less pain, shorter hospital stays, and fewer post-surgical complications such as blood transfusions, infections, deep venous thromboses, and bladder neck contractures.

Purpose: We sought to assess the temporary health-related quality of life (health utility) of nonmagnetic resonance imaging-guided transrectal and transperineal prostate biopsy., Materials and Methods: This is a 2-arm, prospectively enrolled, observational, patient-reported outcomes study, performed between June 2019 and November 2020 at a single academic medical center. Inclusion criteria were men undergoing an outpatient ultrasound-guided prostate biopsy (transrectal or transperineal approach, without magnetic resonance imaging guidance). Patients with a history of Gleason 7+ prostate cancer were excluded. Validated survey instruments were utilized to assess baseline (Short Form 12) and testing-related (Testing Morbidities Index [TMI]) health utility states. The primary outcome was the TMI summary testing-related quality-of-life score (summary utility score; scale: 0=death and 1=perfect health). The TMI is comprised of 7 domains, spanning before, during and after testing experiences. Each domain is scored from 1 (no health impact) to 5 (extreme health impact). Testing-related quality-of-life measures were compared with Mann-Whitney U test., Results: Enrollment rates were 80% (60/75; transrectal) and 86% (60/70; transperineal). All patients (120/120) completed the questionnaire. The TMI summary score for transrectal biopsy was not significantly different from transperineal biopsy (0.86, 95% CI 0.84-0.88 vs 0.83, 95% CI 0.81-0.85; p=0.0774). The largest difference in the testing experiences was related to intraprocedural pain (transrectal biopsy: 2.3, 95% CI 2.1-2.4; transperineal biopsy: 2.9, 95% CI 2.6-3.1; p <0.001)., Conclusions: Transperineal and transrectal prostate biopsies have similar effect on temporary health-related quality-of-life. Transient differences relate to intraprocedural pain. These data can inform clinical decision making and future cost-utility models.

Purpose: The MyProstateScore test was validated for improved detection of clinically significant (grade group ≥2) prostate cancer relative to prostate specific antigen based risk calculators. We sought to validate an optimal MyProstateScore threshold for clinical use in ruling out grade group ≥2 cancer in men referred for biopsy., Materials and Methods: Biopsy naïve men provided post-digital rectal examination urine prior to biopsy. MyProstateScore was calculated using the validated, locked multivariable model including only serum prostate specific antigen, urinary prostate cancer antigen 3 and urinary TMPRSS2:ERG. The MyProstateScore threshold approximating 95% sensitivity for grade group ≥2 cancer was identified in a training cohort, and performance was measured in 2 external validation cohorts. We assessed the 1) overall biopsy referral population and 2) population meeting guideline based testing criteria (ie, prostate specific antigen 3-10, or <3 with suspicious digital rectal examination)., Results: Validation cohorts were prospectively enrolled from academic (977 patients, median prostate specific antigen 4.5, IQR 3.1-6.0) and community (548, median prostate specific antigen 4.9, IQR 3.7-6.8) settings. In the overall validation population (1,525 patients), 338 men (22%) had grade group ≥2 cancer on biopsy. The MyProstateScore threshold of 10 provided 97% sensitivity and 98% negative predictive value for grade group ≥2 cancer. MyProstateScore testing would have prevented 387 unnecessary biopsies (33%), while missing only 10 grade group ≥2 cancers (3.0%). In 1,242 patients meeting guideline based criteria, MyProstateScore ≤10 provided 96% sensitivity and 97% negative predictive value, and would have prevented 32% of unnecessary biopsies, missing 3.7% of grade group ≥2 cancers., Conclusions: In a large, clinically pertinent biopsy referral population, MyProstateScore ≤10 provided exceptional sensitivity and negative predictive value for ruling out grade group ≥2 cancer. This straightforward secondary testing approach would reduce the use of more costly and invasive procedures after screening with prostate specific antigen.

Introduction: Millions of patients take prescription medications each year for common urological conditions. Generic and brand-name drugs have widely divergent pricing despite similar therapeutic benefit and side effect profiles. We examined prescribing patterns across provider types for generic and brand-name drugs used to treat 3 common urological conditions, and estimated economic implications for Medicare Part D spending., Methods: We extracted 2014 prescription claims and payments from Medicare Part D and categorized oral medications used to treat 3 urological conditions, namely benign prostatic hyperplasia, erectile dysfunction and overactive bladder. We examined claims and payments for each medication among urologists and nonurologists. Lastly, we estimated potential savings by selecting a low cost or generic drug as a cost comparator for each class., Results: There were significant differences in prescribing patterns across these conditions, with urologists prescribing more brand-name and expensive medications (p <0.001). The total potential savings related to prescriptions of more expensive and nongeneric drugs in 2014 was $1 billion (benign prostatic hyperplasia $348,454,910, erectile dysfunction $10,211,914 and overactive bladder $698,130,833). These potential savings comprised 53% of the total spending for these medications in 2014., Conclusions: Within Medicare Part D the potential savings associated with generic substitution for higher cost and nongeneric drugs for 3 common urological conditions surpassed $1 billion, with urologists more likely to prescribe brand-name and more expensive drugs. Increasing low cost and generic drug use where available evidence of efficacy is equivocal represents a promising policy target to optimize prescription drug spending.

Purpose: The accumulation of data through a prospective, multicenter coordinated registry network is a practical way to gather real world evidence on the performance of novel prostate ablation technologies. Urological oncologists, targeted biopsy experts, industry representatives and representatives of the FDA (Food and Drug Administration) convened to discuss the role, feasibility and important data elements of a coordinated registry network to assess new and existing prostate ablation technologies., Materials and Methods: A multiround Delphi consensus approach was performed which included the opinion of 15 expert urologists, representatives of the FDA and leadership from high intensity focused ultrasound device manufacturers. Stakeholders provided input in 3 consecutive rounds with conference calls following each round to obtain consensus on remaining items. Participants agreed that these elements initially developed for high intensity focused ultrasound are compatible with other prostate ablation technologies. Coordinated registry network elements were reviewed and supplemented with data elements from the FDA common study metrics., Results: The working group reached consensus on capturing specific patient demographics, treatment details, oncologic outcomes, functional outcomes and complications. Validated health related quality of life questionnaires were selected to capture patient reported outcomes, including the IIEF-5 (International Index of Erectile Function-5), the I-PSS (International Prostate Symptom Score), the EPIC-26 (Expanded Prostate Cancer Index Composite-26) and the MSHQ-EjD (Male Sexual Health Questionnaire for Ejaculatory Dysfunction). Group consensus was to obtain followup multiparametric magnetic resonance imaging and prostate biopsy approximately 12 months after ablation with additional imaging or biopsy performed as clinically indicated., Conclusions: A national prostate ablation coordinated registry network brings forth vital practice pattern and outcomes data for this emerging treatment paradigm in the United States. Our multiple stakeholder consensus identifies critical elements to evaluate new and existing energy modalities and devices., (Copyright © 2018 American Urological Association Education and Research, Inc.

Purpose: The AUA (American Urological Association) QIPS (Quality Improvement and Patient Safety) committee created a white paper on the diagnosis and management of nonneurogenic chronic urinary retention., Materials and Methods: Recommendations for the white paper were based on a review of the literature and consensus expert opinion from the workgroup., Results: The workgroup defined nonneurogenic chronic urinary retention as an elevated post-void residual of greater than 300 mL that persisted for at least 6 months and documented on 2 or more separate occasions. It is proposed that chronic urinary retention should be categorized by risk (high vs low) and symptomatology (symptomatic versus asymptomatic). High risk chronic urinary retention was defined as hydronephrosis on imaging, stage 3 chronic kidney disease or recurrent culture proven urinary tract infection or urosepsis. Symptomatic chronic urinary retention was defined as subjectively moderate to severe urinary symptoms impacting quality of life and/or a recent history of catheterization. A treatment algorithm was developed predicated on stratifying patients with chronic urinary retention first by risk and then by symptoms. The proposed 4 primary outcomes that should be assessed to determine effectiveness of retention treatment are 1) symptom improvement, 2) risk reduction, 3) successful trial of voiding without catheterization, and 4) stability of symptoms and risk over time., Conclusions: Defining and categorizing nonneurogenic chronic urinary retention, creating a treatment algorithm and proposing treatment end points will hopefully spur comparative research that will ultimately lead to a better understanding of this challenging condition., (Copyright © 2017 American Urological Association Education and Research, Inc.

Purpose: To our knowledge it is unknown whether urinary biomarkers for prostate cancer have added utility to clinical risk calculators in different racial groups. We examined the utility of urinary biomarkers added to clinical risk calculators for predicting prostate cancer in African American and nonAfrican American men., Materials and Methods: Demographics, PCPT (Prostate Cancer Prevention Trial) risk scores, data on the biomarkers data PCA3 (prostate cancer antigen 3) and T2ERG (transmembrane protease serine 2 and v-ets erythroblastosis virus E26 oncogene homolog gene fusion), and biopsy pathology features were prospectively collected on 718 men as part of EDRN (Early Detection Research Network). Utility was determined by generating ROC curves and comparing AUC values for the baseline multivariable PCPT model and for models containing biomarker scores., Results: PCA3 and T2ERG added utility for the prediction of prostate cancer and clinically significant prostate cancer when combined with the PCPT Risk Calculator. This utility was seen in nonAfrican American men only for PCA3 (AUC 0.64 increased to 0.75 for prostate cancer and to 0.69-0.77 for clinically significant prostate cancer, both p <0.001) and for T2ERG (AUC 0.64-0.74 for prostate cancer, p <0.001, and 0.69-0.73 for clinically significant prostate cancer, p = 0.029). African American men did not have an added benefit with the addition of biomarkers, including PCA3 (AUC 0.75-0.77, p = 0.64, and 0.65-0.66, p = 0.74) and T2ERG (AUC 0.75-0.74, p = 0.74, and 0.65-0.64, p = 0.88), for prostate cancer and clinically significant prostate cancer, respectively. Limitations include the small number of African American men (72). The post hoc subgroup analysis nature of the study limited findings to being hypothesis generating., Conclusions: As novel biomarkers are discovered, clinical utility should be established across demographically diverse cohorts., (Copyright © 2017 American Urological Association Education and Research, Inc.

Purpose: During active surveillance for localized prostate cancer, the timing of the first surveillance biopsy varies. We analyzed the Canary PASS (Prostate Cancer Active Surveillance Study) to determine biopsy timing influence on rates of prostate cancer adverse reclassification at the first active surveillance biopsy., Materials and Methods: Of 1,085 participants in PASS, 421 had fewer than 34% of cores involved with cancer and Gleason sum 6 or less, and thereafter underwent on-study active surveillance biopsy. Reclassification was defined as an increase in Gleason sum and/or 34% or more of cores with prostate cancer. First active surveillance biopsy reclassification rates were categorized as less than 8, 8 to 13 and greater than 13 months after diagnosis. Multivariable logistic regression determined association between reclassification and first biopsy timing., Results: Of 421 men, 89 (21.1%) experienced reclassification at the first active surveillance biopsy. Median time from prostate cancer diagnosis to first active surveillance biopsy was 11 months (IQR 7.8-13.8). Reclassification rates at less than 8, 8 to 13 and greater than 13 months were 24%, 19% and 22% (p = 0.65). On multivariable analysis, compared to men biopsied at less than 8 months the OR of reclassification at 8 to 13 and greater than 13 months were 0.88 (95% CI 0.5,1.6) and 0.95 (95% CI 0.5,1.9), respectively. Prostate specific antigen density 0.15 or greater (referent less than 0.15, OR 1.9, 95% CI 1.1, 4.1) and body mass index 35 kg/m 2 or greater (referent less than 25 kg/m 2 , OR 2.4, 95% CI 1.1,5.7) were associated with increased odds of reclassification., Conclusions: Timing of the first active surveillance biopsy was not associated with increased adverse reclassification but prostate specific antigen density and body mass index were. In low risk patients on active surveillance, it may be reasonable to perform the first active surveillance biopsy at a later time, reducing the overall cost and morbidity of active surveillance., (Copyright © 2017 American Urological Association Education and Research, Inc.

Purpose: Harms of prostate cancer treatment on urinary health related quality of life have been thoroughly studied. In this study we evaluated not only the harms but also the potential benefits of prostate cancer treatment in relieving the pretreatment urinary symptom burden., Materials and Methods: In American (1,021) and Spanish (539) multicenter prospective cohorts of men with localized prostate cancer we evaluated the effects of radical prostatectomy, external radiotherapy or brachytherapy in relieving pretreatment urinary symptoms and in inducing urinary symptoms de novo, measured by changes in urinary medication use and patient reported urinary bother., Results: Urinary symptom burden improved in 23% and worsened in 28% of subjects after prostate cancer treatment in the American cohort. Urinary medication use rates before treatment and 2 years after treatment were 15% and 6% with radical prostatectomy, 22% and 26% with external radiotherapy, and 19% and 46% with brachytherapy, respectively. Pretreatment urinary medication use (OR 1.4, 95% CI 1.0-2.0, p = 0.04) and pretreatment moderate lower urinary tract symptoms (OR 2.8, 95% CI 2.2-3.6) predicted prostate cancer treatment associated relief of baseline urinary symptom burden. Subjects with pretreatment lower urinary tract symptoms who underwent radical prostatectomy experienced the greatest relief of pretreatment symptoms (OR 4.3, 95% CI 3.0-6.1), despite the development of deleterious de novo urinary incontinence in some men. The magnitude of pretreatment urinary symptom burden and beneficial effect of cancer treatment on those symptoms were verified in the Spanish cohort., Conclusions: Men with pretreatment lower urinary tract symptoms may experience benefit rather than harm in overall urinary outcome from primary prostate cancer treatment. Practitioners should consider the full spectrum of urinary symptom burden evident before prostate cancer treatment in treatment decisions., (Copyright © 2017 American Urological Association Education and Research, Inc.

Purpose: The importance of primary Gleason grade among men with Gleason score 7 disease has been well-defined. However, this dichotomization may oversimplify the continuous spectrum of absolute percent Gleason grade 4 disease (G4%). In this study we report the prognostic value of G4% in cancer related outcomes of men undergoing radical prostatectomy., Materials and Methods: Patients who underwent radical prostatectomy for clinically localized Gleason 6-8 prostate cancer from 2005 to 2013 were included in the study. G4% was determined as biopsy tumor length containing Gleason pattern 4/total tumor length, which performed better than alternative quantifications of pattern 4 involvement. G4% was correlated with time to biochemical recurrence and presence of adverse radical prostatectomy pathology, defined as primary Gleason 4 or pT3 or greater, by multivariable Cox and logistic regressions., Results: Of 1,691 patients 517 (30.6%) had adverse pathological features and 86 (5.6%) experienced biochemical recurrence. On multivariable analyses G4% was a significant predictor of adverse pathology (OR 1.04, 95% CI 1.03-1.05) and time to biochemical recurrence (HR 1.02, CI 1.01-1.03). G4% was also a significant independent predictor of adverse pathology in subsets of patients with Gleason score 7 (OR 1.05, 95% CI 1.03-1.06), 3+4 (OR 1.06, 95% CI 1.04-1.08) and 4+3 cancer (OR 1.05, 95% CI 1.03-1.06). We found a significantly increased risk of adverse pathology at potentially meaningful G4% thresholds (1% to 10% vs 20% to 30%)., Conclusions: The incremental percentage of Gleason grade 4 disease in biopsy specimens is an important predictor of adverse pathology and biochemical recurrence across the entire range of G4% disease. Accounting for G4% can improve risk assessment even among those patients with Gleason 3+4 or 4+3 cancer and may help inform patient counseling., (Copyright © 2016 American Urological Association Education and Research, Inc.

Purpose: Active surveillance represents a strategy to address the overtreatment of prostate cancer, yet uncertainty regarding individual patient outcomes remains a concern. We evaluated outcomes in a prospective multicenter study of active surveillance., Materials and Methods: We studied 905 men in the prospective Canary PASS enrolled between 2008 and 2013. We collected clinical data at study entry and at prespecified intervals, and determined associations with adverse reclassification, defined as increased Gleason grade or greater cancer volume on followup biopsy. We also evaluated the relationships of clinical parameters with pathology findings in participants who underwent surgery after a period of active surveillance., Results: At a median followup of 28 months 24% of participants experienced adverse reclassification, of whom 53% underwent treatment while 31% continued on active surveillance. Overall 19% of participants received treatment, 68% with adverse reclassification, while 32% opted for treatment without disease reclassification. In multivariate Cox proportional hazards modeling the percent of biopsy cores with cancer, body mass index and prostate specific antigen density were associated with adverse reclassification (p=0.01, 0.04, 0.04, respectively). Of 103 participants subsequently treated with radical prostatectomy 34% had adverse pathology, defined as primary pattern 4-5 or nonorgan confined disease, including 2 with positive lymph nodes, with no significant relationship between risk category at diagnosis and findings at surgery (p=0.76)., Conclusions: Most men remain on active surveillance at 5 years without adverse reclassification or adverse pathology at surgery. However, clinical factors had only a modest association with disease reclassification, supporting the need for approaches that improve the prediction of this outcome., (Copyright © 2016 American Urological Association Education and Research, Inc.

Purpose: Most prostate cancer active surveillance protocols recommend a confirmatory biopsy within 3 to 6 months of diagnosis. Transperineal template guided biopsy is an approach to improve the detection of high grade prostate cancer. However, to our knowledge the optimal technique is unknown. We evaluated the relative performance of 2 transperineal template guided biopsy approaches., Materials and Methods: Institutional review board approved prospective databases at Virginia Mason and University of Michigan were used. Men eligible for active surveillance based on initial 12-core biopsy demonstrating NCCN® guideline low risk prostate cancer were included in study. All men underwent confirmatory transperineal template guided biopsy between 2005 and 2014, and within 6 months of diagnosis. The biopsy technique was based on a 24-core template with 12 anterior and 12 posterior cores or a template based on gland volume with an average of 1 core per cc. Outcome comparisons were made by the chi-square and Fisher exact tests, the Welch t-test and linear regression., Results: Of the 135 men 46 underwent 24-core biopsy and 89 underwent volume based biopsy (median 62 cores). No statistically significant difference was noted in the prevalence of upgrading (35% vs 29%, p = 0.64) or complications (9% vs 16%, p = 0.38) between the 24-core and volume based groups. The difference in the probability of upgrading by volume based biopsy adjusted for age, prostate specific antigen, prostate volume, clinical stage and number of prior biopsies was -4% (95% CI -24 to 14%, p = 0.63)., Conclusions: A significant difference was not detected in upgrading or morbidity between a 24-core template and a more exhaustive volume based template. A less invasive 24-core transperineal template guided biopsy strategy may suffice to accurately identify men who are appropriate for active surveillance., (Copyright © 2015 American Urological Association Education and Research, Inc.

Purpose: We evaluated the ability of PHI to discriminate aggressive prostate cancer from indolent or no cancer in a biopsy naïve population., Materials and Methods: Two independent prospective cohorts of 561 and 395 subjects, respectively, with no prior prostate biopsy who were enrolled at different clinical sites were used to validate the results. We compared the diagnostic specificity of PHI to prebiopsy total and percent free prostate specific antigen using prostate biopsy results. We also determined the optimal PHI threshold to discriminate aggressive prostate cancer (Gleason score 7 or greater) from indolent or no prostate cancer (Gleason score 6 or less)., Results: In the primary cohort higher PHI values were significantly associated with Gleason score 7 or greater. The AUC to detect aggressive prostate cancer was 0.815. At 95% sensitivity PHI specificity was 36.0% vs 17.2% and 19.4% for total and percent free prostate specific antigen, respectively. At 95% sensitivity for detecting aggressive prostate cancer the optimal PHI cutoff was 24, which would help avoid 41% of unnecessary biopsies. A cutoff of 24 led to 36% biopsies avoided with few aggressive cancers missed. These results were confirmed in the validation cohort., Conclusions: The PHI detected aggressive prostate cancer with better specificity than total and percent free prostate specific antigen in a biopsy naïve population. It could be a useful tool to decrease unnecessary prostate biopsies., (Copyright © 2015 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.)

Purpose: The Prostate Health Index (phi) is a new test combining total, free and [-2]proPSA into a single score. It was recently approved by the FDA and is now commercially available in the U.S., Europe and Australia. We investigate whether phi improves specificity for detecting clinically significant prostate cancer and can help reduce prostate cancer over diagnosis., Materials and Methods: From a multicenter prospective trial we identified 658 men age 50 years or older with prostate specific antigen 4 to 10 ng/ml and normal digital rectal examination who underwent prostate biopsy. In this population we compared the performance of prostate specific antigen, % free prostate specific antigen, [-2]proPSA and phi to predict biopsy results and, specifically, the presence of clinically significant prostate cancer using multiple criteria., Results: The Prostate Health Index was significantly higher in men with Gleason 7 or greater and "Epstein significant" cancer. On receiver operating characteristic analysis phi had the highest AUC for overall prostate cancer (AUCs phi 0.708, percent free prostate specific antigen 0.648, [-2]proPSA 0.550 and prostate specific antigen 0.516), Gleason 7 or greater (AUCs phi 0.707, percent free prostate specific antigen 0.661, [-2]proPSA 0.558, prostate specific antigen 0.551) and significant prostate cancer (AUCs phi 0.698, percent free prostate specific antigen 0.654, [-2]proPSA 0.550, prostate specific antigen 0.549). At the 90% sensitivity cut point for phi (a score less than 28.6) 30.1% of patients could have been spared an unnecessary biopsy for benign disease or insignificant prostate cancer compared to 21.7% using percent free prostate specific antigen., Conclusions: The new phi test outperforms its individual components of total, free and [-2]proPSA for the identification of clinically significant prostate cancer. Phi may be useful as part of a multivariable approach to reduce prostate biopsies and over diagnosis., (Copyright © 2015 American Urological Association Education and Research, Inc.

Purpose: The Affordable Care Act (ACA) is expected to provide coverage for nearly twenty-five million previously uninsured individuals. Because the potential impact of the ACA for urological care remains unknown, we estimated the impact of insurance expansion on the utilization of inpatient urological surgeries using Massachusetts (MA) healthcare reform as a natural experiment., Methods: We identified nonelderly patients who underwent inpatient urological surgery from 2003 through 2010 using inpatient databases from MA and two control states. Using July 2007 as the transition point between pre- and post-reform periods, we performed a difference-indifferences (DID) analysis to estimate the effect of insurance expansion on overall and procedure-specific rates of inpatient urological surgery. We also performed subgroup analyses according to race, income and insurance status., Results: We identified 1.4 million surgeries performed during the study interval. We observed no change in the overall rate of inpatient urological surgery for the MA population as a whole, but an increase in the rate of inpatient urological surgery for non-white and low income patients. Our DID analysis confirmed these results (all 1.0%, p=0.668; non-whites 9.9%, p=0.006; low income 6.6%, p=0.041). At a procedure level, insurance expansion caused increased rates of inpatient BPH procedures, but had no effect on rates of prostatectomy, cystectomy, nephrectomy, pyeloplasty or PCNL., Conclusions: Insurance expansion in Massachusetts increased the overall rate of inpatient urological surgery only for non-whites and low income patients. These data inform key stakeholders about the potential impact of national insurance expansion for a large segment of urological care.

Introduction: There are concerns that the availability of in-office ancillary services may lower thresholds for evaluation, leading to the overuse of testing without clear benefit. Motivated by this issue, we analyzed nationally representative survey data, and examined for associations between the availability of in-office laboratory services and the use of prostate specific antigen testing., Methods: Using restricted data from the 2006-2008 NAMCS, we determined the prevalence of physician practices offering on-site laboratory services. We then characterized differences between practices with and without these capabilities as well as among the physicians working in them. Finally, we fitted multivariable logistic regression models to estimate the odds of prostate specific antigen testing given a man's mortality risk and the availability of in-office laboratory services at the practice where he received care., Results: Approximately half of all primary care and urology practices offered in-office laboratory services. Practice characteristics associated with these capabilities included practice size (p <0.001) and breadth of specialization (p = 0.021). Employed physicians were more likely to work in practices with in-office laboratory services than self-employed physicians (p <0.001). On multivariable regression the availability of on-site laboratory services was not associated with the use of prostate specific antigen testing (OR 0.86, 95% CI 0.62-1.20, p = 0.362). In fact, the probability of prostate specific antigen testing among patients with the highest mortality risk was lower if they were seen at a practice with in-office laboratory services., Conclusions: These findings provide some reassurance that in-office ancillaries do not lead to overuse of prostate specific antigen testing.

Purpose: We examined variation in active surveillance use in Medicare eligible men undergoing expectant treatment for early stage prostate cancer., Materials and Methods: Using SEER (Surveillance, Epidemiology and End Results) and Medicare data we identified 49,192 men diagnosed with localized prostate cancer from 2004 through 2007. Of 7,347 patients who did not receive treatment (ie expectant management) within 12 months of diagnosis we assessed the prevalence of active surveillance (ie repeat prostate biopsy and prostate specific antigen measurement) vs watchful waiting across health care markets. We fit multivariable logistic regression models to examine associations of active surveillance with patient demographics, cancer severity and health care market characteristics., Results: During the study interval use of active surveillance vs watchful waiting increased significantly in patients treated expectantly from 9.7% in 2004 to 15.3% in 2007 (p <0.001). Active surveillance was less common in older patients, those with high risk tumors and those with more comorbidities (each p <0.001). Patients who were white and had higher socioeconomic status were more likely to receive active surveillance (each p <0.05). After adjusting for patient and tumor characteristics significant differences in the predicted probability of active surveillance persisted across health care markets (range 2.4% to 30.1%). No significant variation in active surveillance use was associated with specific health care market characteristics, including intensity of end of life care, Medicare reimbursement or provider density., Conclusions: Active surveillance has been relatively uncommon in Medicare beneficiaries with localized prostate cancer. Its use relative to watchful waiting varies based on patient demographics, tumor severity and geographic location., (Copyright © 2014 American Urological Association Education and Research, Inc.

Purpose: After being diagnosed with prostate cancer men must assimilate information regarding the cancer. Satisfaction with information reflects the evaluation of information sources used before treatment to select a therapy. We describe the use and helpfulness of several information sources available to prostate cancer survivors. We also identified factors associated with satisfaction with information., Materials and Methods: A total of 1,204 men with newly diagnosed prostate cancer were enrolled in the prospective, multicenter Prostate Cancer Outcomes and Satisfaction with Therapy Quality Assessment study. The validated satisfaction with information domain of the Service Satisfaction Scale-Cancer was administered to subjects 2 months after treatment. The relationship between several factors, such as demographics, socioeconomic factors, cancer severity and types of information sources, and satisfaction with information were evaluated using multiple regression., Results: Sources of information endorsed by subjects varied by race, education and study site. The most helpful sources were treatment description by the treating physician (33.1%), Internet sites (18.9%) and books (18.1%). In multiple variable models patient age (p = 0.005) and information provided by the physician regarding outcomes in their patients (p = 0.01) were independently associated with patient satisfaction with the information provided., Conclusions: Various information sources were used and endorsed as helpful by subjects, although results for physician patients was the only source independently associated with satisfaction with information. Providing patients with information about possible or expected courses of care and outcomes may improve satisfaction., (Copyright © 2014 American Urological Association Education and Research, Inc.

Purpose: We expanded the clinical usefulness of EPIC-CP (Expanded Prostate Cancer Index Composite for Clinical Practice) by evaluating its responsiveness to health related quality of life changes, defining the minimally important differences for an individual patient change in each domain and applying it to a sexual outcome prediction model., Materials and Methods: In 1,201 subjects from a previously described multicenter longitudinal cohort we modeled the EPIC-CP domain scores of each treatment group before treatment, and at short-term and long-term followup. We considered a posttreatment domain score change from pretreatment of 0.5 SD or greater clinically significant and p ≤ 0.01 statistically significant. We determined the domain minimally important differences using the pooled 0.5 SD of the 2, 6, 12 and 24-month posttreatment changes from pretreatment values. We then recalibrated an EPIC-CP based nomogram model predicting 2-year post-prostatectomy functional erection from that developed using EPIC-26., Results: For each health related quality of life domain EPIC-CP was sensitive to similar posttreatment health related quality of life changes with time, as was observed using EPIC-26. The EPIC-CP minimally important differences in changes in the urinary incontinence, urinary irritation/obstruction, bowel, sexual and vitality/hormonal domains were 1.0, 1.3, 1.2, 1.6 and 1.0, respectively. The EPIC-CP based sexual prediction model performed well (AUC 0.76). It showed robust agreement with its EPIC-26 based counterpart with 10% or less predicted probability differences between models in 95% of individuals and a mean ± SD difference of 0.0 ± 0.05 across all individuals., Conclusions: EPIC-CP is responsive to health related quality of life changes during convalescence and it can be used to predict 2-year post-prostatectomy sexual outcomes. It can facilitate shared medical decision making and patient centered care., (Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Purpose: We performed a meta-analysis to compare treatment with α-blockers and anticholinergics (ie combination therapy) to α-blocker monotherapy to clarify the efficacy and safety of this treatment approach among men with storage urinary symptoms related to benign prostatic hyperplasia., Materials and Methods: We searched for trials of men with benign prostatic hyperplasia/lower urinary tract symptoms that were randomized to combination treatment or α-blockers alone. We pooled data from 7 placebo controlled trials meeting inclusion criteria. Primary outcomes of interest included changes in International Prostate Symptom Score (storage subscores) and urinary frequency. We also assessed post-void residual volume, maximal flow rate and the incidence of urinary retention. Data were pooled using random effects models for continuous outcomes and the Peto method to generate odds ratios for acute urinary retention., Results: Combination therapy had a significantly greater reduction in International Prostate Symptom Score storage subscores (Δ -0.73, 95% CI -1.09 - -0.37) and voiding frequency (Δ -0.69 voids, 95% CI -0.97 - -0.41). There was also a greater reduction in maximal urinary flow rate (Δ -0.59 ml per second, 95% CI -1.04 - -0.14) and increase in post-void residual urine volume (Δ 11.60 ml, 95% CI 8.50-14.70) with combination therapy. The number needed to treat with combination therapy to cause 1 acute urinary retention episode was 101 (95% CI 60-267)., Conclusions: Combination treatment with α-blockers and anticholinergics significantly improved storage voiding parameters compared to men treated with α-blocker therapy alone. This treatment approach is safe with a minimal risk of increased post-void residual urine volume, decreased maximal urinary flow rate or acute urinary retention., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: While the dissemination of robotic prostatectomy and intensity modulated radiotherapy may fuel the increased use of prostatectomy and radiotherapy, these new technologies may also have spillover effects related to diagnostic testing for prostate cancer. Therefore, we examined the association of regional technology penetration with the receipt of prostate specific antigen testing and prostate biopsy., Materials and Methods: In this retrospective cohort study we included 117,857 men 66 years old or older from the 5% sample of Medicare beneficiaries living in Surveillance, Epidemiology and End Results (SEER) areas from 2003 to 2007. Regional technology penetration was measured as the number of providers performing robotic prostatectomy or intensity modulated radiotherapy per population in a health care market, ie hospital referral region. We assessed the association of technology penetration with the prostate specific antigen testing rate and prostate biopsy using generalized estimating equations., Results: High technology penetration was associated with an increased rate of prostate specific antigen testing (442 vs 425/1,000 person-years, p<0.01) and a similar rate of prostate biopsy (10.1 vs 9.9/1,000 person-years, p=0.69). The impact of technology penetration on prostate specific antigen testing and prostate biopsy was much less than the effect of age, race and comorbidity, eg the prostate specific antigen testing rate per 1,000 person-years was 485 vs 373 for men with only 1 vs 3+ comorbid conditions (p<0.01)., Conclusions: Increased technology penetration is associated with a slightly higher rate of prostate specific antigen testing and no change in the prostate biopsy rate. Collectively, our findings temper concerns that adopting new technology accelerates diagnostic testing for prostate cancer., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Hopes are high that the delivery system reforms embodied in the patient centered medical home will improve the quality of care for patients with chronic diseases. While primary care physicians, given their training, will likely be the locus of care under this model, there are certain conditions for which urologists are well suited to provide the continuous and comprehensive care called for by the patient centered medical home. To assess the feasibility of the urology based patient centered medical home, we analyzed national survey data., Materials and Methods: For our measure of medical home infrastructure, we mapped items from the 2007 and 2008 NAMCS (National Ambulatory Medical Care Survey) to the NCQA (National Committee on Quality Assurance) standards for patient centered medical home recognition. We determined the proportion of urology practices in the United States that would achieve patient centered medical home recognition. Finally, we used NAMCS data to estimate the impact of consolidating genitourinary cancer (ie prostate, bladder, kidney and testis) followup care among the current supply of urologists., Results: Nearly three-quarters of urology practices meet NCQA standards for patient centered medical home recognition. At present, primary care physicians spend 9,295 cumulative workweeks providing direct and indirect care to survivors of genitourinary cancers. Off-loading half of this care to urology practices, in the context of the patient centered medical home, would generate an average of 0.73 additional workweeks for each practicing urologist., Conclusions: Urology practices may possess the capacity needed to direct medical homes for their patients with genitourinary cancers. Successful implementation of this model would likely require a willingness to manage some nonurological conditions., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Photoselective vaporization of the prostate has become an increasingly popular option for the treatment of benign prostatic hyperplasia. However, delayed bleeding has been raised as a potential issue as more cases are performed. We characterize delayed bleeding after photoselective vaporization of the prostate and identify associated risk factors., Materials and Methods: We defined delayed gross hematuria as any complaint of hematuria following hospital discharge, and further stratified it as delayed gross hematuria requiring emergency department evaluation, hospital admission, continuous bladder irrigation, transfusions or reoperation. We performed an explicit chart review of 290 patients who underwent photoselective vaporization of the prostate at a single center from 2002 through 2009. Exposures of interest included age, prostate volume, followup duration, operative factors (watts/joules), and use of oral anticoagulation therapy or 5α-reductase inhibitors., Results: Delayed gross hematuria occurred in 33.8% of patients during an average followup of 33 months. For 8.5% of patients the bleeding was severe enough to prompt presentation to the emergency department. For 4.8% of patients hospitalization was required and for 4.5% reoperation was required. Multivariate analysis revealed that the odds of bleeding increased with prostate size (OR 1.08, 1.03-1.14), longer followup (OR 1.35, 1.12-1.62) and anticoagulant use (OR 3.35, 1.43-7.83), and decreased with increasing age (OR 0.71, 0.51-0.98) and use of a 5α-reductase inhibitor (OR 0.41, 0.24-0.73)., Conclusions: Delayed hematuria occurs commonly after photoselective vaporization of the prostate but severe hematuria is rare. Larger prostate size, longer followup and use of anticoagulation were associated with a higher risk of delayed gross hematuria while preoperative 5α-reductase inhibitor use and older age were protective., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: We assessed the independent predictive value of prostate volume, number of biopsy cores and AUASS (American Urological Association symptom score) compared to risk factors included in the PCPTRC (Prostate Cancer Prevention Trial risk calculator for prostate cancer) and PCPTHG (Prostate Cancer Prevention Trial risk calculator for high grade cancer [Gleason grade 7 or greater])., Materials and Methods: Of 5,519 PCPT (Prostate Cancer Prevention Trial) participants used to construct the PCPTRC 4,958 with AUASS and prostate specific antigen 10 ng/ml or less were included on logistic regression analysis. Risk algorithms were evaluated in 571 EDRN (Early Detection Research Network) participants using the ROC AUC., Results: A total of 1,094 participants (22.1%) had prostate cancer, of whom 232 (21.2%) had high grade disease. For prostate cancer prediction higher prostate specific antigen, abnormal digital rectal examination, family history of prostate cancer and number of cores were associated with increased risk, while volume was associated with decreased risk. Excluding prostate volume and number of cores, a history of negative biopsy and increased AUASS were also associated with lower risk. For high grade cancer higher prostate specific antigen, abnormal digital rectal examination, black race and number of cores were associated with increased risk and volume, while AUASS was associated with decreased risk. The AUC of the PCPTRC adjusted for volume and number of cores was 72.7% (using EDRN data), 68.2% when adjusted for AUASS alone and 67.6% PCPTRC. For high grade disease the AUCs were 74.8%, 74.0% and 73.5% (PCPTHG), respectively., Conclusions: Adjusted PCPT risk calculators for volume, number of cores and AUASS improve cancer detection., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Reported prostate specific antigen values may differ substantially among assays using Hybritech® or WHO standardization. The Beckman Coulter® Prostate Health Index and [-2]proPSA are newly approved serum markers associated with prostate cancer risk and aggressiveness. We studied the influence of assay standardization on these markers., Materials and Methods: Prostate specific antigen, percent free prostate specific antigen and [-2]proPSA were measured using Hybritech calibration in 892 men from a prospective, multicenter study undergoing prostate biopsy. We calculated the Prostate Health Index using the equation, ([-2]proPSA/free prostate specific antigen) × PSA. Index performance characteristics for prostate cancer detection were then determined using recalculated WHO calibration prostate specific antigen values., Results: The median Prostate Health Index was significantly higher in men with prostate cancer than in those with negative biopsies using WHO values (47.4 vs 39.8, p <0.001). The index offered improved discrimination of prostate cancer detection on biopsy (AUC 0.704) compared to percent free or total prostate specific antigen using the WHO calibration., Conclusions: The Prostate Health Index can be calculated using Hybritech or WHO standardized assays. It significantly improved prediction of the biopsy outcome over that of percent free or prostate specific antigen alone., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: The G84E variant of HOXB13 was recently found to be associated with a significantly increased risk of prostate cancer in a case control study. We estimated the prevalence of this mutation in a clinical population of men at risk for prostate cancer who were scheduled to undergo prostate biopsy., Materials and Methods: We prospectively collected clinical information and DNA samples from men who underwent diagnostic prostate biopsy between June 2005 and October 2011. We genotyped samples for HOXB13 G84E using the MassARRAY® system. We determined the prevalence of the G84E variant in the overall cohort, among patients with a positive family history and among men age 55 years or younger., Results: A total of 1,175 subjects underwent biopsy, of whom 948 had a DNA sample for analysis. The G84E variant was detected in 4 patients (prevalence 0.42%, 95% CI 0.12-1.08), of whom 3 had prostate cancer on biopsy. None of 301 patients with a positive family history (prevalence 0.00%, 95% CI 0.00-1.22) and 1 of 226 patients age 55 years or younger tested positive (prevalence 0.44%, 95% CI 0.01-2.44)., Conclusions: The HOXB13 G84E variant is rare in this cohort, even among those with a positive family history. Our findings question the utility of testing for this variant among unselected men presenting for a diagnostic prostate biopsy., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: The uncertainty about the incremental benefit of robotic prostatectomy and its higher associated costs makes it an ideal target for state based certificate of need laws, which have been enacted in several states. We studied the relationship between certificate of need laws and market level adoption of robotic prostatectomy., Materials and Methods: We used SEER (Surveillance, Epidemiology, and End Results)-Medicare data from 2003 through 2007 to identify men 66 years old or older treated with prostatectomy for prostate cancer. Using data from the American Health Planning Association, we categorized Health Service Areas according to the stringency of certificate of need regulations (ie low vs high stringency) presiding over that market. We assessed our outcomes (probability of adopting robotic prostatectomy and propensity for robotic prostatectomy use in adopting Health Service Areas) using Cox proportional hazards and Poisson regression models, respectively., Results: Compared to low stringency markets, high stringency markets were more racially diverse (54% vs 15% nonwhite, p <0.01), and had similar population densities (886 vs 861 people per square mile, p = 0.97) and median incomes ($42,344 vs $39,770, p = 0.56). In general, both market types had an increase in the adoption and utilization of robotic prostatectomy. However, the probability of robotic prostatectomy adoption (p = 0.22) did not differ based on a market's certificate of need stringency and use was lower in high stringency markets (p <0.01)., Conclusions: State based certificate of need regulations were ineffective in constraining robotic surgery adoption. Despite decreased use in high stringency markets, similar adoption rates suggest that other factors impact the diffusion of robotic prostatectomy., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Benign prostatic hyperplasia is a highly prevalent disease in older men with substantial adverse effects on public health. Classic etiological paradigms for benign prostatic hyperplasia focus on nonmodifiable risk factors. However, obesity also potentially promotes benign prostatic hyperplasia., Materials and Methods: We performed a structured, comprehensive literature review to identify studies of obesity, benign prostatic hyperplasia, lower urinary tract symptoms and physical activity., Results: A preponderance of published evidence suggests strong positive associations of obesity with benign prostatic hyperplasia and lower urinary tract symptoms. This evidence encompasses most established metrics of adiposity, including body mass index, waist circumference and waist-to-hip ratio, and falls under 3 general categories, including prostate volume, clinical benign prostatic hyperplasia and lower urinary tract symptoms. 1) Prior studies consistently showed that increased adiposity is positively associated with radiographically determined prostate volume and enlargement, suggesting that obesity promotes prostate growth. 2) Most studies revealed that obesity increases the risk of clinical benign prostatic hyperplasia by several measures, including the initiation of benign prostatic hyperplasia medical treatment, noncancer prostate surgery, physician diagnosed benign prostatic hyperplasia, histological diagnosis and urinary flow rate. 3) Prior studies demonstrated that obesity increases the risk of lower urinary tract symptoms, as measured by a validated questionnaire. Also, most studies showed that physical activity significantly decreases the risk of benign prostatic hyperplasia., Conclusions: Obesity markedly increases the risk of benign prostatic hyperplasia. Since physical activity decreases the risk of benign prostatic hyperplasia, these observations support the development of novel prevention strategies and treatment targeted toward adiposity, weight loss and lifestyle., (Copyright © 2013 American Urological Association Education and Research, Inc.

Purpose: Laser prostatectomy has increased in popularity in the last decade. However, traditional transurethral resection of the prostate remains common. To understand decisions about the use of laser prostatectomy vs transurethral prostate resection, we evaluated trends in transurethral surgery for benign prostatic hyperplasia in an all payer data set, focusing on patient and provider factors associated with the receipt of laser prostatectomy., Materials and Methods: Using Florida State Inpatient Database and Ambulatory Surgery Database, we identified patients who underwent laser prostatectomy or transurethral prostate resection from 2001 to 2009. We calculated surgery rates with time, stratified by procedure type. We used multilevel regression to examine patient (age, race and comorbidity level) and provider (surgeon volume) factors associated with the receipt of laser prostatectomy vs transurethral prostate resection., Results: While the overall rates of transurethral surgery remained stable during the study period (p = 0.227), laser prostatectomy use increased 400% from 25 to 114 procedures per 100,000 men (p <0.001), replacing about half of all transurethral prostate resections. Patients were less likely to undergo laser prostatectomy if they were older (OR 0.65, 95% CI 0.61-0.70) and less healthy (OR 0.48, 95% CI 0.45-0.51). While these factors were predictive of surgery type, most of the variation in laser prostatectomy use (69%) was determined by the urologist seen by the patient., Conclusions: Laser prostatectomy use has increased in the last decade at the expense of transurethral prostate resection, driven largely by provider effects. However, elderly and more infirm patients are least likely to undergo it, raising concern about underuse in this population., (Copyright © 2012 American Urological Association Education and Research, Inc.

Purpose: Given the increased attention to the quality and cost of medical care, the Institute of Medicine and Centers for Medicare and Medicaid Services have called for performance measurement and reporting. The clinical management of prostate cancer has been outlined, yet is not intended to describe quality prostate cancer care. Therefore, RAND researchers developed quality indicators for early stage prostate cancer. The ACoS (American College of Surgeons) used these indicators to perform the first national assessment to our knowledge of the quality of care among men with early stage prostate cancer undergoing expectant management., Materials and Methods: Information from medical records was abstracted for evidence of compliance with the RAND indicators (structure and process). Weighted and stratified proportions were calculated to assess indicator compliance. Logistic regression models were fit and evaluated by hospital type and patient factors., Results: A weighted and stratified total of 13,876 early stage prostate cancer cases on expectant management in 2000 to 2001 were investigated. Compliance with structural indicators was high (greater than 80%) and compliance with process indicators varied (19% to 87%). Differences in process indicators were observed from models by hospital type and comorbid conditions, but not for age, race or insurance status., Conclusions: Using the RAND quality indicators this study revealed several process areas for quality improvement among men with early stage prostate cancer on expectant management in the United States. Efforts to improve the quality of early stage prostate cancer care need to move beyond the paradigm of age, race and insurance status., (Copyright © 2012 American Urological Association Education and Research, Inc.

Purpose: Benign prostatic hyperplasia creates significant expenses for the Medicare program. We determined expenditure trends for benign prostatic hyperplasia evaluative testing after urologist consultation and placed these trends in the context of overall Medicare expenditures., Materials and Methods: Using a 5% national sample of Medicare beneficiaries from 2000 to 2007 we developed a cohort of 40,253 with claims for new visits to urologists for diagnoses consistent with symptomatic benign prostatic hyperplasia. We assessed trends in initial inflation and geography adjusted expenditures within 12 months of diagnosis by evaluative test categories derived from the 2003 American Urological Association guideline on the management of benign prostatic hyperplasia. Using governmental reports on Medicare expenditure trends for benign prostatic hyperplasia we compared expenditures to overall and imaging specific Medicare expenditures. Comparisons were assessed by the Z-test and regression analysis for linear trends, as appropriate., Results: Between 2000 and 2007 inflation adjusted total Medicare expenditures per patient for the initial evaluation of patients with benign prostatic hyperplasia seen by urologists increased from $255.44 to $343.98 (p <0.0001). Benign prostatic hyperplasia related imaging increases were significantly less than overall Medicare imaging expenditure increases (55% vs 104%, p <0.001). The increase in per patient expenditures for benign prostatic hyperplasia was significantly lower than the increase in overall Medicare expenditures per enrollee (35% vs 45%, p = 0.0015)., Conclusions: From 2000 to 2007 inflation adjusted expenditures increased for benign prostatic hyperplasia related evaluations. This growth was slower than the overall growth in Medicare expenditures. The increase in BPH related imaging expenditures was restrained compared to that of the Medicare program as a whole., (Copyright © 2012 American Urological Association Education and Research, Inc.

Purpose: In addition to their acute implications, adverse events after oncological surgery may have late or long-term consequences for patient outcomes. We assessed the relationship between postoperative complications and long-term survival among patients treated surgically for kidney cancer., Materials and Methods: Using Surveillance, Epidemiology and End Results-Medicare data we identified patients with kidney cancer treated surgically from 1995 through 2005. After excluding from analysis those who died during the index hospitalization or within 30 days of surgery we compared overall survival for patients with or without a postoperative complication. We then fit multivariate Cox proportional hazard models to estimate the association between complications and long-term survival, adjusting for patient characteristics, cancer severity and surgical approach., Results: We identified 4,687 (37%) and 7,931 patients (63%) with and without a postoperative complication, respectively. During a median followup of 32 months (range 1 to 132) 3,425 patients (27.1%) died of any cause. Patients with at least 1 postoperative complication had lower unadjusted 5-year survival (59.9% vs 69.5%, p <0.001). On multivariate analyses the occurrence of a complication was also associated with significantly worse long-term survival (HR 1.24, 95% CI 1.16-1.33). This relationship was consistent with time, across surgical approaches and among patients with various specific complications, including acute renal failure, cardiac and neurological events, postoperative infection and sepsis., Conclusions: The occurrence of a postoperative complication is associated with decreased long-term survival after surgery for kidney cancer. Clarification of the cascade of events underlying this relationship may lead to new strategies to improve outcomes among cancer survivors., (Copyright © 2012 American Urological Association Education and Research, Inc.

Purpose: Since to our knowledge the population level impact of laparoscopy on post-radical nephrectomy morbidity and mortality remains unknown, we compared the rates of postoperative complications and failure to rescue (the fatality rate in patients with a complication) in patients treated with laparoscopic vs open radical nephrectomy., Materials and Methods: Using linked SEER (Surveillance, Epidemiology and End Results)-Medicare data we identified patients with kidney cancer who were treated with laparoscopic or open radical nephrectomy from 2000 through 2005. After measuring the frequency of postoperative complications and failure to rescue we fit multivariate logistic regression models to estimate the association of these outcomes with surgical approach, adjusting for patient characteristics, cancer severity and surgery year. We also assessed the relationship between case volume, complications and failure to rescue., Results: We identified 2,108 (26%) and 5,895 patients (74%) treated with laparoscopic and open radical nephrectomy, respectively. The overall rates of complications and failure to rescue were 36.9% and 5.3%, respectively. The predicted probability of any, major, medical and surgical complications was 15%, 12%, 13% and 23% lower, respectively, after laparoscopic than after open radical nephrectomy (each p <0.05). Despite less frequent complications patients treated with laparoscopic radical nephrectomy had a greater probability of failure to rescue (7.6% vs 4.6%, p = 0.010). Higher volume surgeons and hospitals had a lower rate of failure to rescue in patients treated with radical nephrectomy (each p <0.05) but not with open radical nephrectomy., Conclusions: Supporting the decreased morbidity of laparoscopy, patients treated with radical nephrectomy had fewer complications than those who underwent open radical nephrectomy. However, failure to rescue was more common in patients with a complication after radical nephrectomy, suggesting that these events may be more difficult to recognize and manage successfully, especially among less experienced surgeons and hospitals., (Copyright © 2011 American Urological Association Education and Research, Inc.

Purpose: Measuring the health related quality of life of patients with prostate cancer in routine clinical practice is hindered by the lack of instruments enabling efficient, real-time, point of care scoring of multiple health related quality of life domains. Thus, we developed an instrument for this purpose., Materials and Methods: The Expanded Prostate Cancer Index Composite for Clinical Practice is a 1-page, 16-item questionnaire that we constructed to measure urinary incontinence, urinary irritation, and the bowel, sexual and hormonal health related quality of life domains. We eliminated conceptually overlapping items from the 3-page Expanded Prostate Cancer Index Composite-26 and revised the questionnaire format to mirror the AUA symptom index, thereby enabling practitioners to calculate health related quality of life scores at the point of care. We administered the Expanded Prostate Cancer Index Composite for Clinical Practice to a new cohort of patients with prostate cancer in community based and academic oncology, radiation, and urology practices to evaluate instrument validity as well as ease of use in clinical practice., Results: A total of 175 treated and 132 untreated subjects with prostate cancer completed the Expanded Prostate Cancer Index Composite for Clinical Practice. The domain scores of the Expanded Prostate Cancer Index Composite for Clinical Practice correlated highly with the respective domain scores from longer versions of the Expanded Prostate Cancer Index Composite (r≥0.93 for all domains). The Expanded Prostate Cancer Index Composite for Clinical Practice showed high internal consistency (Cronbach's α 0.64-0.84) and sensitivity to prostate cancer treatment related effects (p<0.05 in each of 5 health related quality of life domains). Patients completed the Expanded Prostate Cancer Index Composite for Clinical Practice efficiently (96% in less than 10 minutes and with 11% missing items). It was deemed very convenient by clinicians in 87% of routine clinical encounters and clinicians accurately scored completed questionnaires 94% of the time., Conclusions: The Expanded Prostate Cancer Index Composite for Clinical Practice is a valid instrument that enables patient reported, health related quality of life to be measured efficiently and accurately at the point of care, and thereby facilitates improved emphasis and management of patient reported outcomes., (Copyright © 2011 American Urological Association Education and Research, Inc.

Purpose: We examined the evaluation of and management for lower urinary tract symptoms/benign prostatic hyperplasia by physician specialty (urologist vs primary care physician)., Materials and Methods: The BPH Registry and Patient Survey is a longitudinal, observational, disease registry cohort of patients enrolled from January 2004 to February 2005 in the United States. The survey examines patient outcomes and physician practice patterns in the management of lower urinary tract symptoms associated with clinical benign prostatic hyperplasia. It includes 402 urologist and primary care physician practices throughout the United States. Included in this study were 6,924 men with lower urinary tract symptoms/benign prostatic hyperplasia managed by watchful waiting or medical therapy. Data were collected on demographics, clinical characteristics and lower urinary tract symptoms/benign prostatic hyperplasia management using physician and patient completed forms. Multivariate analysis was done by physician specialty., Results: Based on multivariate analysis urologists were more likely than primary care physicians to perform urinalysis (OR 3.9), serum prostate specific antigen (OR 1.2) and post-void residual urine (OR 18.9) measurement, uroflowmetry (OR 17.3), prostate ultrasound (OR 7.7) and biopsy (OR 3.5), renal ultrasound (OR 4.0) and cystoscopy (OR 4.6) but less likely to measure creatinine (OR 0.1). Men seeing urologists were twice as likely as men seeing primary care physicians to be treated with benign prostatic hyperplasia medical therapy vs watchful waiting. Significant differences by physician specialty were also observed for specific benign prostatic hyperplasia medical therapies., Conclusions: Significant differences in practice patterns were observed between primary care physicians and urologists in the evaluation of and management for lower urinary tract symptoms/benign prostatic hyperplasia. These data establish valuable benchmarks and identify possible interventions that may improve the standard of care., (Copyright © 2011 American Urological Association Education and Research, Inc.

Purpose: We describe longitudinal trends in surgeon adoption of laparoscopic radical nephrectomy. We assessed whether this technique is associated with specific surgeon and/or practice setting characteristics., Methods and Materials: We used Surveillance, Epidemiology and End Results-Medicare data to identify patients who underwent laparoscopic or open radical nephrectomy for early stage kidney cancer from 1995 through 2005. We assessed long-term trends in surgeon adoption of laparoscopic radical nephrectomy and fit multilevel logistic regression models to estimate the association between surgeon or practice setting characteristics and patient receipt of laparoscopic radical nephrectomy., Results: The annual proportion of patients receiving laparoscopic radical nephrectomy increased from 1.4% in 1995 to 44.9% in 2005 (p <0.001). In patients treated by recent medical school graduates (graduation year 1991 or thereafter) the likelihood of undergoing laparoscopic radical nephrectomy was more than 2-fold higher when urologists practiced at National Cancer Institute designated Cancer Centers (OR 2.37, 95% CI 1.11-5.06) or in urban settings (OR 2.92, 95% CI 1.10-7.75). Patients treated by urologists who graduated before 1991 and had a major academic affiliation (OR 1.78, 95% CI 1.34-2.38) or were in a group practice (OR 1.99, 95% CI 1.51-2.63) were significantly more likely to be treated with a minimally invasive surgical approach than those treated in nonacademic and solo practices, respectively., Conclusions: Urologist adoption of laparoscopic radical nephrectomy increased progressively from 1995 through 2005 and was influenced by urologist proximity to training, academic affiliation and rural/urban status. These data clarify residual barriers to surgeon adoption of laparoscopic radical nephrectomy and potentially of other innovative surgical therapies., (Copyright © 2011 American Urological Association Education and Research, Inc.

Purpose: To revise the 2003 version of the American Urological Association's (AUA) Guideline on the management of benign prostatic hyperplasia (BPH)., Materials and Methods: From MEDLINE® searches of English language publications (January 1999 through February 2008) using relevant MeSH terms, articles concerning the management of the index patient, a male ≥45 years of age who is consulting a healthcare provider for lower urinary tract symptoms (LUTS) were identified. Qualitative analysis of the evidence was performed. Selected studies were stratified by design, comparator, follow-up interval, and intensity of intervention, and meta-analyses (quantitative synthesis) of outcomes of randomized controlled trials were planned. Guideline statements were drafted by an appointed expert Panel based on the evidence., Results: The studies varied as to patient selection; randomization; blinding mechanism; run-in periods; patient demographics, comorbidities, prostate characteristics and symptoms; drug doses; other intervention characteristics; comparators; rigor and intervals of follow-up; trial duration and timing; suspected lack of applicability to current US practice; and techniques of outcomes measurement. These variations affected the quality of the evidence reviewed making formal meta-analysis impractical or futile. Instead, the Panel and extractors reviewed the data in a systematic fashion and without statistical rigor. Diagnosis and treatment algorithms were adopted from the 2005 International Consultation of Urologic Diseases. Guideline statements concerning pharmacotherapies, watchful waiting, surgical options and minimally invasive procedures were either updated or newly drafted, peer reviewed and approved by AUA Board of Directors., Conclusions: New pharmacotherapies and technologies have emerged which have impacted treatment algorithms. The management of LUTS/BPH continues to evolve., (Copyright © 2011 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.)

Purpose: Prostate specific antigen and free prostate specific antigen have limited specificity to detect clinically significant, curable prostate cancer, leading to unnecessary biopsy, and detection and treatment of some indolent tumors. Specificity to detect clinically significant prostate cancer may be improved by [-2]pro-prostate specific antigen. We evaluated [-2]pro-prostate specific antigen, free prostate specific antigen and prostate specific antigen using the formula, ([-2]pro-prostate specific antigen/free prostate specific antigen × prostate specific antigen(1/2)) to enhance specificity to detect overall and high grade prostate cancer., Materials and Methods: We enrolled 892 men with no history of prostate cancer, normal rectal examination, prostate specific antigen 2 to 10 ng/ml and 6-core or greater prostate biopsy in a prospective multi-institutional trial. We examined the relationship of serum prostate specific antigen, free-to-total prostate specific antigen and the prostate health index with biopsy results. Primary end points were specificity and AUC using the prostate health index to detect overall and Gleason 7 or greater prostate cancer on biopsy compared with those of free-to-total prostate specific antigen., Results: In the 2 to 10 ng/ml prostate specific antigen range at 80% to 95% sensitivity the specificity and AUC (0.703) of the prostate health index exceeded those of prostate specific antigen and free-to-total prostate specific antigen. An increasing prostate health index was associated with a 4.7-fold increased risk of prostate cancer and a 1.61-fold increased risk of Gleason score greater than or equal to 4 + 3 = 7 disease on biopsy. The AUC of the index exceeded that of free-to-total prostate specific antigen (0.724 vs 0.670) to discriminate prostate cancer with Gleason 4 or greater + 3 from lower grade disease or negative biopsy. Prostate health index results were not associated with age and prostate volume., Conclusions: The prostate health index may be useful in prostate cancer screening to decrease unnecessary biopsy in men 50 years old or older with prostate specific antigen 2 to 10 ng/ml and negative digital rectal examination with minimal loss in sensitivity., (Copyright © 2011 American Urological Association Education and Research, Inc.

Purpose: Most men live with rather than die of prostate cancer. As a result, survivors have a protracted course, harboring considerable clinical and economic implications. Thus, we investigated the extent to which health service use and expenditures vary during continuing prostate cancer care., Materials and Methods: We identified 105,961 patients diagnosed with prostate cancer between 1992 and 2005 using Surveillance, Epidemiology and End Results-Medicare data. All Medicare payments for prostate cancer related care were assigned to a phase of care (initial, continuing care or end of life), price adjusted and standardized. Patients were sorted into 5 equal groups (quintiles) based on annual per capita continuing care expenditures. We then enumerated the use of common prostate cancer health services., Results: Average annual per capita continuing care phase expenditures were $36 to $4,724 in the lowest to the highest expenditure group, respectively. Office visits (27.3%) and androgen deprivation (62.7%) comprised most physician related payments for prostate cancer survivorship care. The use of each common health service grew with increasing continuing care intensity (each p <0.001). However, the magnitude of variation in each prostate cancer risk stratum was substantially greater than that between risk strata, eg low risk and metastatic disease, in patients with similar spending., Conclusions: In Medicare beneficiaries the prostate cancer continuing care phase is associated with substantial variation, resulting in potentially unnecessary excess cost to the health care system. Variation was evident across the spectrum of disease severity and implies the need for better evidence to inform clinical practice., (Copyright (c) 2010 American Urological Association Education and Research, Inc.

Purpose: We developed and validated a reliable, responsive multidimensional instrument to measure disease specific health related quality of life in bladder cancer survivors treated with local cancer therapy., Materials and Methods: Instrument content was based on qualitative information obtained from a panel of bladder cancer providers and from patient focus groups. Draft items were piloted and revised, resulting in the 36-item Bladder Cancer Index consisting of urinary, bowel and sexual health domains. Internal consistency, test-retest reliability, convergent validity, concurrent validity and criterion validity were then assessed., Results: Internal consistency was high at 0.77 to 0.91. Test-retest reliability was also high at 0.73 to 0.95. Correlations among the 3 domains were low (r < or = 0.39), indicating interscale independence. Health outcome discrimination was apparent in clinically distinct treatment groups. Moderate correlation was observed with existing external measures, indicating that the Bladder Cancer Index detects aspects of health related quality of life related to bladder cancer treatments that are not recorded by more general measures., Conclusions: The Bladder Cancer Index is a robust, multidimensional measure of bladder cancer specific health related quality of life and to our knowledge is the first available validated instrument to assess health outcomes across a range of local treatments commonly used for bladder cancer., (2010 American Urological Association Education and Research, Inc.

Purpose: Benign prostatic hyperplasia and associated lower urinary tract symptoms are highly prevalent in older men and represent a substantial challenge to public health. Apart from the prevalence of benign prostatic hyperplasia increasing with age, little is understood regarding its etiology and natural history. Increasing evidence recently pointed toward relationships between diabetes and benign prostatic hyperplasia/lower urinary tract symptoms. We present an overview of the current understanding of clinical and epidemiological research on diabetes and benign prostatic hyperplasia/lower urinary tract symptoms, the hypothesized pathophysiological mechanisms linking the conditions and recommendations for future directions for research., Materials and Methods: A structured, comprehensive literature review was done to identify studies of the relationships between benign prostatic hyperplasia and lower urinary tract symptoms, and diabetes in older men., Results: A substantial proportion of the existing body of literature supports an association between diabetes and benign prostatic hyperplasia/lower urinary tract symptoms. However, failure to differentiate lower urinary tract symptoms from benign prostatic hyperplasia contributed to some of the confusing evidence in studies including more specific benign prostatic hyperplasia measurements. This could be due in part to the largely cross-sectional analyses, the use of select or different study populations, limited sample sizes and inadequate control of potential confounders., Conclusions: Diabetes may substantially influence the risk of benign prostatic hyperplasia and lower urinary tract symptoms in older men. Further prospective, longitudinal analyses of the impact of diabetes and its etiological mechanisms on benign prostatic hyperplasia/lower urinary tract symptoms may identify novel interventions to prevent, diagnose and treat these highly prevalent conditions.

Purpose: The Prostate Cancer Prevention Trial prostate cancer risk calculator was developed in a clinical trial cohort that does not represent men routinely referred for prostate biopsy. We assessed the generalizability of the Prostate Cancer Prevention Trial calculator in a cohort more representative of patients referred for consideration of prostate biopsy in American urology practice., Materials and Methods: Patients undergoing prostate biopsy by 12 urologists at 5 sites were enrolled in an Early Detection Research Network cohort. The Prostate Cancer Prevention Trial risk calculator was validated by examining area underneath the receiver operating characteristic curve, sensitivity, specificity and calibration comparing observed vs predicted risk of prostate cancer detection., Results: Cancer incidence was greater (43% vs 22%, p = 0.001) in the Early Detection Research Network validation cohort (645) compared to the Prostate Cancer Prevention Trial group (5,519). Early Detection Research Network participants were younger and more racially diverse, and had more abnormal digital rectal examinations and higher prostate specific antigen than Prostate Cancer Prevention Trial participants (all p <0.001). Cancer severity was worse in the Early Detection Research Network cohort than in the Prostate Cancer Prevention Trial (Gleason 7 or higher 60% vs 21%, p <0.001). Nevertheless, the Prostate Cancer Prevention Trial risk calculator was superior to prostate specific antigen alone for predicting cancer in the Early Detection Research Network (AUC 0.691 vs 0.655, p = 0.009) and calibration confirmed that the Prostate Cancer Prevention Trial risk score accurately predicted individual risks in the Early Detection Research Network cohort., Conclusions: Differences between the Early Detection Research Network validation cohort and the Prostate Cancer Prevention Trial cohort underscore the importance of validating calculator performance in the multicenter urology practice setting. Our findings extend the applicability of the Prostate Cancer Prevention Trial calculator for measuring the risk of prostate cancer detection on biopsy to the routine American urology practice setting.

Purpose: Benign prostatic hyperplasia is a highly prevalent disease in older men with substantial adverse effects on public health. Classic etiological paradigms for benign prostatic hyperplasia focus on nonmodifiable risk factors. However, obesity also potentially promotes benign prostatic hyperplasia., Materials and Methods: We performed a structured, comprehensive literature review to identify studies of obesity, benign prostatic hyperplasia, lower urinary tract symptoms and physical activity., Results: A preponderance of published evidence suggests strong positive associations of obesity with benign prostatic hyperplasia and lower urinary tract symptoms. This evidence encompasses most established metrics of adiposity, including body mass index, waist circumference and waist-to-hip ratio, and falls under 3 general categories, including prostate volume, clinical benign prostatic hyperplasia and lower urinary tract symptoms. 1) Prior studies consistently showed that increased adiposity is positively associated with radiographically determined prostate volume and enlargement, suggesting that obesity promotes prostate growth. 2) Most studies revealed that obesity increases the risk of clinical benign prostatic hyperplasia by several measures, including the initiation of benign prostatic hyperplasia medical treatment, noncancer prostate surgery, physician diagnosed benign prostatic hyperplasia, histological diagnosis and urinary flow rate. 3) Prior studies demonstrated that obesity increases the risk of lower urinary tract symptoms, as measured by a validated questionnaire. Also, most studies showed that physical activity significantly decreases the risk of benign prostatic hyperplasia., Conclusions: Obesity markedly increases the risk of benign prostatic hyperplasia. Since physical activity decreases the risk of benign prostatic hyperplasia, these observations support the development of novel prevention strategies and treatment targeted toward adiposity, weight loss and lifestyle.

Purpose: The introduction of efficacious pharmacotherapies has effectively transformed benign prostatic hyperplasia into a chronic disease that requires ongoing medical care. With this transformation primary care physicians have become more involved in the management of benign prostatic hyperplasia. The impact of the increasing role of the primary care physician on the use of benign prostatic hyperplasia related health services remains unknown., Materials and Methods: We performed a retrospective cohort study using medical claims from a nonprofit managed care organization. Between 1997 and 2005 we identified incident cases of benign prostatic hyperplasia and the provider responsible for the initial care. We fitted logistic regression models to measure the association between subject receipt of an evaluative process and the treating physician specialty. Furthermore, we examined differences between primary care physicians and urologists with respect to the use of medical therapy., Results: Less than a third of incident cases received initial care from a urologist. Use of office based procedures and urodynamic tests was exclusive to urology. Urologists performed urinalysis testing and transrectal ultrasonography more frequently than primary care physicians (p <0.001). The odds of having a laboratory study doubled with treatment by a urologist (OR 2.03, 95% CI 1.51-2.74). Men seen by a urologist were also more likely to be prescribed a benign prostatic hyperplasia medication (p <0.001). Among those who received medical therapy, prescription of selective alpha-adrenergic blockers, 5alpha-reductase inhibitors and combination therapy was higher among urologists (p = 0.002)., Conclusions: On average, urologists had a higher intensity practice style for benign prostatic hyperplasia than primary care physicians. Further studies are needed to determine how these practice style differences relate to patient clinical outcomes.

Purpose: To decrease the cost of surgical care Medicare has introduced a new facility fee schedule for ambulatory surgical centers. This prospective payment system increases reimbursement for many urological procedures, while decreasing reimbursement for others. All stakeholders, including physicians, the Medicare program and hospitals, will be affected by these changes., Materials and Methods: Using the Agency for Healthcare Research and Quality State Ambulatory Surgery Databases we identified Medicare patients in Florida who underwent urological procedures in ambulatory surgical centers from 1998 to 2005. Three facility groupings were created, including urology dominant, multispecialty and other specialty dominant. The impact of reimbursement changes at the procedure and facility levels was assessed using 2005 data. Projections of ambulatory surgical center use and reimbursement in 2008 were then generated using all available data., Results: In 2008 we project total payments by Medicare to increase by $4,233,080 (26%, range 22% to 32%) under the new reimbursement system compared to the old system. At the facility level reimbursement to multispecialty facilities should increase substantially (49%), while urology specialty facilities will receive less benefit (10% increase). Compared to multispecialty facilities, at urology specialty facilities a higher proportion of cases is performed for which reimbursement is set to decrease., Conclusions: Under the new payment scheme for ambulatory surgical centers winners and losers emerge. Facilities with diversified procedure mixes will find increased revenue, while those with less diversification will find slower growth to their revenue streams. In contrast to the desire of the Medicare program to decrease surgical costs, the new program may increase the payments made for urological surgery.

Purpose: The clinical manifestations of benign prostatic hyperplasia that are more likely to bring black men in for care have not been well characterized. We examined associations between lower urinary tract symptom severity measures and subsequent health care seeking behavior in a population based sample of black men., Materials and Methods: In 2000, 165 black men from Genesee County, Michigan who were 40 to 79 years old without a history of prostate cancer/surgery provided information on lower urinary tract symptoms and health care seeking behaviors. The associations between physician visits regarding lower urinary tract symptoms and symptom frequency, perceived bother, impact on daily activities and quality of life were examined, controlling for age and sociodemographic characteristics., Results: Overall 22.2% of men sought medical advice for lower urinary tract symptoms. Men with moderate/severe symptom severity and associated bother had 4.9 and 3.0-fold increased odds, respectively, of having sought medical care for their symptoms compared to those with mild/no symptom severity or bother. Greater increases in physician visits were observed for increases in benign prostatic hyperplasia impact (OR 5.7, 95% CI 1.9-17.1), quality of life (OR 5.2, 95% CI 2.2-12.2) and worsening symptoms (OR 3.8, 95% CI 1.6-8.7). Health care seeking was associated with irritative and obstructive symptom severity (OR 1.4, 95% CI 1.2-1.6 and OR 1.2, 95% CI 1.1-1.3, respectively)., Conclusions: In this population based study of black American men we found that worsening urinary symptoms, associated bother, impact and quality of life were significantly associated with health care seeking behavior. Irritative symptom severity was most highly associated with health care seeking behavior. Further evaluations are necessary to determine whether racial differences exist in health care seeking behavior for lower urinary tract symptoms.
