- Abstract
Purpose: Men with low risk prostate cancer on active surveillance undergo multiple biopsies over time. The long-term clinical significance of consecutively negative biopsies is not known., Materials and Methods: Men with low risk prostate cancer prospectively enrolled in an active surveillance database with at least 4 biopsies were included in the study. Exposure variables were 0, 1 or 2 consecutively negative biopsies after diagnosis. Other variables included age, prostate specific antigen, prostate specific antigen density, Gleason grade group, percent positive cores and magnetic resonance imaging findings. Outcome variables were the detection of any cancer at fourth biopsy and active treatment., Results: A total of 514 men were included, with 112 (22%) men having 1 negative biopsy and 78 (15%) with 2 consecutively negative biopsies. Median prostate specific antigen density was lower for men with 1 negative biopsy (0.11) and consecutively negative biopsies (0.10) compared to men who never had a negative biopsy (0.13, p <0.01). On univariable logistic regression higher prostate specific antigen density (OR 1.68, 95% CI 1.16-2.45) and suspicious magnetic resonance imaging lesions (OR 2.00, 95% CI 1.16-3.42) were associated with a higher likelihood of detecting cancer on fourth biopsy. On multivariable logistic regression 1 negative biopsy (OR 0.22, 95% CI 0.12-0.41) and consecutively negative biopsies (OR 0.12, 95% CI 0.06-0.24) were associated with a lower likelihood of detecting cancer at outcome biopsy. Unadjusted 10-year treatment-free survival was highest for patients with consecutively negative biopsies (84%) and 1 negative biopsy (74%) than those who had none (66%) (log rank p=0.02)., Conclusions: Consecutively negative surveillance biopsies are correlated with favorable clinical risk factors and independently associated with subsequent negative biopsy and lower risk of active treatment.

- Abstract
Purpose: Few validated clinical tools currently exist to standardize the frequency of biopsies for men on active surveillance for low risk prostate cancer. We determined predictors of biopsy reclassification at specific time points after enrollment on active surveillance., Materials and Methods: We identified men with clinically low risk prostate cancer prospectively enrolled on active surveillance at the University of California, San Francisco between 2000 and 2016. Biopsy reclassification was defined as Gleason Grade Group 2 or greater on subsequent biopsy. Multivariable Cox proportional hazards regression models were used to identify factors associated with risk of biopsy reclassification at first surveillance biopsy and 1 to 3, 3 to 5 and 5 to 10 years after enrollment, adjusting for clinicodemographic factors, PI-RADS® (Prostate Imaging Reporting and Data System) score and genomic testing., Results: A total of 1,031 men were included in the study. On multivariable analysis biopsy reclassification was associated with prostate specific antigen density 0.15 or greater (HR 3.37, 95% CI 1.83-6.21), percentage biopsy cores positive (HR 1.27, 95% CI 1.05-1.54) and high genomic score (HR 2.81, 95% CI 1.21-6.52) at first surveillance biopsy and also at 1 to 3 years, after adjustment. Prostate specific antigen density 0.15 or greater (HR 2.36, 95% CI 1.56-3.56) and prostate specific antigen kinetics (HR 2.19, 95% CI 1.43-3.34) were associated with reclassification at 3 to 5 years. A PI-RADS 4-5 score was not associated with biopsy reclassification at any time point., Conclusions: High genomic score, prostate specific antigen kinetics and prostate specific antigen density 0.15 or greater were associated with reclassification within 3 years of commencing active surveillance, and prostate specific antigen kinetics and prostate specific antigen density 0.15 or greater remained associated with reclassification at 5 years after diagnosis.

- Abstract
Importance: Active surveillance (AS) is now recognized as the preferred management option for most low-risk prostate cancers to minimize risks of overtreatment. Despite increasing use of AS in the US, wide regional variability has been observed, and these regional variations in contemporary practice have not been well described., Objective: To explore variations between county and Surveillance, Epidemiology, and End Results (SEER) regions in AS in the US., Design, Setting, and Participants: A cohort study using the SEER Prostate with Watchful Waiting (WW) database linked to the County Area Health Resource File for detailed county-level demographics and physician distribution data was conducted from January 2010 to December 2015. Analysis was performed in October 2020. A total of 79 825 men with clinically localized, low-risk prostate cancer eligible for AS or WW were included., Exposures: Multiple patient-, county-, and SEER region-level factors, including age, year of diagnosis, county-level densities of urologists, radiation oncologists, primary care physicians, and SEER registry region., Main Outcomes and Measures: Use of AS or WW as the initial reported treatment strategy were noted. Hierarchical mixed-effect logistic regression models were used to evaluate clustered random regional variation on use of AS or WW. Temporal trends by year in proportions of initial treatment type, as well as county-level local variation, were also estimated., Results: Of 79 825 men (mean [SD] age, 62.8 [7.6] years, 11 292 [14.1%] non-Hispanic Black, 7506 [9.4%] Hispanic) with low-risk prostate cancer, the mean annualized percent increase in AS rates from 2010 to 2015 ranged from 6.3% in New Mexico to 81.0% in New Jersey. Differences across SEER regions accounted for 17% of the total variation in AS. Increasing age (51-60 years: odds ratio [OR], 1.33; 95% CI, 1.21-1.46; 61-70 years: OR, 1.86; 95% CI, 1.70-2.04; 71-80 years: OR, 2.26; 95% CI, 2.05-2.50) was associated with greater odds of AS. Hispanic ethnicity (OR, 0.79; 95% CI, 0.74-0.85), T category (OR, 0.79; 95% CI, 0.73-0.84), and Medicaid enrollment (OR, 0.73; 95% CI, 0.66-0.81) were associated with lower odds of AS. Black race, county-level socioeconomic factors (household income, educational level, and city type), and specialist densities were not associated with AS use., Conclusions and Relevance: In this US cohort study based on the SEER-WW database, although the use of AS increased, considerable practice variation appeared to be associated with geographic location, but use of AS was not associated with Black race, specialty professional density, or socioeconomic factors. This small area variation underlies the broader national trends in AS practice and may inform policies aimed at continuing to affect risk-appropriate care for men throughout the US.

- Abstract
Purpose: We assessd the long-term outcomes from a large prospective cohort of men diagnosed with prostate cancer managed with active surveillance and determined the clinical prognostic factors that may predict the risk of metastases., Materials and Methods: We retrospectively reviewed data of men enrolled on active surveillance at our institution between 1990 and 2018 with low or intermediate risk disease (stage cT1-2, prostate specific antigen less than 20 ng/ml, and biopsy Grade Group [GG]1-2). Patients were classified into 3 groups by diagnostic GG and prostate specific antigen density. Primary outcome was metastatic prostate cancer detected on imaging or at prostatectomy. In addition, upgrade at surveillance biopsy, active treatment, and overall and prostate cancer specific survival outcomes were assessed. Cox proportional hazards regression models were used., Results: A total of 1,450 men met the inclusion criteria. Median followup was 77 months (IQR 49-114). The 7-year metastasis-free survival rate was 99%. Metastases developed in 15 men at a median of 62 months (IQR 29-104), of which 69% were confined to lymph nodes. Men with GG2 had a lower metastasis-free survival rate compared to those with GG1 disease. GG2, prostate specific antigen velocity and PI-RADS® 4-5 lesions on multiparametric magnetic resonance imaging were associated with a higher risk of metastases. The 7-year prostate cancer specific survival was greater than 99%., Conclusions: Active surveillance seems to preserve favorable long-term prognosis, as metastases and prostate cancer specific death are rare. However, the higher risk of metastases associated with higher Gleason grade, prostate specific antigen velocity, and characteristics on multiparametric magnetic resonance imaging should be considered when selecting and counseling patients for active surveillance.

- Abstract
Patients with chronic disease and mental illness are at higher risk of depression and suicide. Many who have been diagnosed with genitourinary cancers are at higher risk of suicide, even among those who have sought out mental health services. Under-represented populations (African-American, Hispanic, elderly, disabled) suffer disproportionately from a lack of mental health services. However, not much is reported on the interplay of mental health and genitourinary cancer in these populations. This review aims to identify the relevant literature and describe a path forward to address and alleviate this disparity. PATIENT SUMMARY: Patients with chronic disease and mental illness are at higher risk of depression and suicide. Little is known about the complex interplay between race and mental health in patients with urologic cancers and more research is needed., (Copyright © 2019 European Association of Urology.

- Abstract
Background: Black individuals with muscle-invasive bladder cancer (MIBC) experienced 21% lower odds of guideline-based treatment (GBT) and differences in treatment explain 35% of observed Black-White differences in survival. Yet little is known of how interactions between race/ethnicity and receipt of GBT drive within- and between-race survival differences., Methods: Black, White, and Latino individuals diagnosed with nonmetastatic, locally advanced MIBC from 2004 to 2013 within the National Cancer Database were included. Guideline-based treatment was defined as the receipt including one or more of the following treatment modalities: radical cystectomy (RC), neoadjuvant chemotherapy with RC, RC with adjuvant chemotherapy, and/or chemoradiation based on American Urological Association guidelines. Cox proportional hazards model of mortality estimated effects of GBT status, race/ethnicity, and the GBT-by-race/ethnicity interaction, adjusting for covariates., Results: Of the 54 910 MIBC individuals with 125 821 person-years of posttreatment observation (max = 11 years), 6.9% were Black, and 3.0% were Latino. Overall, 51.4%, 45.3%, and 48.5% of White, Black, and Latino individuals received GBT. Latino individuals had lower hazard of death compared to Black (HR 0.81, 95% CI 0.75-0.87) and White individuals (HR 0.92, 95% 0.86-0.98). With GBT, Latino and White individuals had similar outcomes (HR = 1.00, 95% 0.91-1.10) and both fared better than Black individuals (HR = 0.88, 95% 0.79-0.99 and HR = 0.88, 95% 0.83-0.94, respectively). Without GBT, Latino individuals fared better than White (HR = 0.85, 95% 0.77-0.93) and Black individuals (HR = 0.74, 95% 0.67-0.82) while White individuals fared better than Black individuals (HR = 0.87, 95% 0.83-0.92). Black individuals with GBT fared worse than Latinos without GBT (HR = 1.02, 95% 0.92-1.14), although not statistically significant., Conclusion: Low GBT levels demonstrated an "under-allocation" of GBT to those who needed it most-Black individuals. Interventions to improve GBT allocation may mitigate race-based survival differences observed in MIBC., (© 2020 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

- Abstract
Background: Active surveillance (AS)/watchful waiting (WW) strategy for localized prostate cancer (PCa) is increasingly and broadly endorsed as a preferred option for initial treatment of men with very low- and low-risk PCa, but outcomes can be difficult to analyze in traditional, population-based registries. The recently released Surveillance, Epidemiology, and End Results (SEER) Prostate with WW dataset provides an opportunity to understand national patterns and trends in AS/WW, but the data source itself has not been well described., Objective: To provide a comprehensive description of this dataset and investigate possible biases due to missing data., Design, Setting, and Participants: The SEER is a population-based epidemiologic registry in the USA. Newly diagnosed PCa patient data were collected from 18 SEER registries between 2010 and 2015, with inclusion of a new treatment variable for AS/WW. We identified 316 724 patients in the entire cohort and 257 060 men with clinically localized PCa (T1-2N0M0)., Intervention: Various primary treatments for PCa., Outcome Measurements and Statistical Analysis: The degree of missing data for each variable was measured. In order to investigate possible bias due to missing data for cancer characterization, we compared two versions of the data: one that excluded cases with missing data and one dataset generated applying multiple imputations., Results and Limitations: Only 46% of cases had complete data on basic cancer characteristics for risk stratification. The excluded dataset (N=118 821) differed significantly from the multiple imputation dataset (N=257 060) in the distribution of every reported variable (all p<0.001). The dataset does not distinguish WW from AS, which is a limitation., Conclusions: While the SEER Prostate with WW dataset offers a new method to describe treatment trends for men with PCa, including the use of AS/WW, the amount of missing data should not be ignored., Patient Summary: While the Surveillance, Epidemiology, and End Results Prostate with Watchful Waiting dataset offers a new method to describe treatment trends for men with prostate cancer, including the use of active surveillance, it has a significant amount of missing data, which can be a source of potential bias if not addressed properly., (Copyright © 2020 European Association of Urology.

- Abstract
Background: Testicular sex cord stromal tumors (SCSTs) are managed similarly to germ cell tumors (GCTs); however, few studies have directly compared outcomes between these tumor types. Using the National Cancer Database (NCDB), we sought to compare overall and stage-specific all-cause mortality (ACM) between SCSTs versus GCTs., Methods: NCDB was queried for patients diagnosed with SCSTs and GCTs between 2004 and 2013. Descriptive statistics were used to compare sociodemographic and clinical characteristics between groups. Univariable and multivariable Cox proportional hazards regression analyses were used to assess associations with ACM., Results: We identified 42,192 patients diagnosed with testicular cancer between 2004 and 2013, with 280 having SCSTs and 41,912 patients having GCTs. Median age for SCSTs and GCTs was 45 (interquartile range [IQR] 34-59) and 34 (IQR 27-43), respectively (p < 0.001). Median follow-up was 39 and 52 months, respectively. Overall, patients with SCSTs had greater risk of ACM compared to those with GCTs (HR 1.69, 95% CI 1.14-2.50). Private insurance, greater education, and fewer comorbidities were associated with reduced risk of ACM (p < 0.05 for all). Among those with stage I disease, tumor type was not associated with ACM on multivariable analysis. Among those with stage II/III disease, patients with SCSTs had increased risk of ACM compared to patients with GCTs (HR 3.29, 95% CI 1.89-5.72)., Conclusions: Patients with advanced SCSTs had worse survival outcomes compared to those with advanced GCTs. These data suggest a need for further investigation to ascertain effective management recommendations for SCSTs.

- Abstract
OBJECTIVE. Elevated prostate-specific antigen density (PSAD) based on transrectal ultrasound (TRUS) measurements has been shown to be strongly associated with clinically significant disease and to predict progression on active surveillance (AS) for men with disease that is at a low stage or grade. We hypothesized that elevated MRI PSAD is similarly associated with increased risk of progression on subsequent biopsy. MATERIALS AND METHODS. In this retrospective study, men with Gleason score of 3+3 on diagnostic TRUS-guided biopsy who were managed with AS, had undergone MRI, and had at least one additional biopsy were included. MRI PSAD was calculated using prostate volume on MRI and prostate-specific antigen level temporally closest to the MRI. Multivariable logistics regression models were used to evaluate the association between MRI PSAD and predictors of upgrade on serial biopsy. RESULTS. A total of 166 patients were identified, of whom 74 (44.6%) were upgraded to a Gleason score of 7 or higher on subsequent biopsy. Lesions with Prostate Imaging Reporting and Data System (PI-RADS) scores of 4 and 5 more commonly had MRI PSAD of 0.15 ng/mL
2 or higher (51.93% vs 22.22%, p = 0.01) than lesions with PI-RADS scores of 1-3. Median MRI PSAD was significantly higher in the upgraded group compared with the group that was not upgraded (0.15 ng/mL2 vs 0.11 ng/mL2 , p = 0.01). MRI PSAD was significantly associated with increased odds of upgrading on subsequent biopsy (log transformation; odds ratio, 1.9 [95% CI, 1.2-2.8]; p = 0.01) after adjusting for age and length of follow-up. CONCLUSION. MRI PSAD was significantly associated with Gleason score upgrading on subsequent biopsy for men initially diagnosed with Gleason 3+3 disease. Although this result is intuitive, to our knowledge it has not been previously shown. As MRI utilization increases, MRI PSAD can aid in risk stratification for men managed with AS.- Published

- Abstract
Purpose of Review: Active surveillance is becoming more widely accepted as an initial management option for carefully selected men with favorable intermediate-risk prostate cancer (PCa). As prospective active surveillance cohorts mature sufficiently to begin evaluating longer-term outcomes, consensus on more precise evidence-based guidelines is needed to identify the patient cohorts who may be safely managed with active surveillance and what the ideal surveillance protocol entails., Recent Findings: Long-term outcomes updates have suggested a trend toward worse 15-year survival outcomes for intermediate-risk patients on active surveillance compared with definitive treatment, but 'intermediate-risk' is a broad category and there is a subset of favorable intermediate-risk patients for whom survival outcomes remain equivalent. Promising updates to current risk stratification include consideration of genomic classifiers, advanced imaging and more nuanced interpretation of biopsy results., Summary: Despite widespread acknowledgement of the pitfalls of overtreatment in clinically localized PCa, utilization of active surveillance in the intermediate-risk population remains marginal, in part due to the absence of easily interpretable consensus recommendations. As more long-term outcomes data become available for this subgroup, the field is now poised to refine the definition of favorable intermediate-risk patients for whom active surveillance is a safe, evidence-based first-line management option.

- Abstract
Purpose: Genomic testing may improve risk stratification in men with prostate cancer managed by active surveillance. We aimed to characterize the stability and usefulness of serial genomic test scores in men undergoing serial biopsies during active surveillance., Materials and Methods: We compiled clinical and disease characteristics of men on active surveillance using an institutional Urologic Outcomes Database. We included patients initially diagnosed with Gleason 3 + 3 prostate cancer who elected active surveillance and received 2, 17-gene GPS (Genomic Prostate Score) results. We examined the association of GPS results and Gleason grade reclassification (Gleason 3 + 4 or greater) with definitive treatment using multivariable Cox proportional hazards regression models., Results: We identified 111 men who underwent serial genomic testing. There were 49 grade reclassification events (44%) at a median followup of 64 months. The mean ± SD GPS change between the first and second biopsies was 2.1 ± 10.3. The GPS at first biopsy (per 5 units HR 1.04, 95% CI 1.00-1.07, p=0.03) was associated with an upgrade at second biopsy, although the second GPS was not (HR 1.02, 95% CI 0.99-1.05, p=0.13). The first and second GPSs (HR 1.09, 95% CI 1.04-1.14 and HR 1.09, 95% CI 1.04-1.14, each p <0.01) were associated with active treatment., Conclusions: The GPS undergoes small changes with time. Absolute GPS results at the first and second biopsies were associated with Gleason upgrading and transition from active surveillance to active treatment.

- Abstract
Introduction: American Urological Association (AUA) guidelines recommend percutaneous nephrolithotomy (PCNL) for total stone burden greater than 20 mm, yet it is unclear if the number of stones affects adherence to this guideline. We aim to assess the impact of stone multiplicity on the choice of ureteroscopy (URS) vs PCNL as a first-line therapy for patients with high burden (>20 mm), and examine whether the AUA guideline-discordant care impacts patient outcomes. Materials and Methods: Data were collected from the Registry for Stones of the Kidney and Ureter (ReSKU) database, a prospectively collected registry of patients with stone disease. Multivariate logistic regression (MLR) was used to estimate the association between stone multiplicity and the decision to perform URS for high stone burden (>20 mm) patients. MLR was further used to estimate the association between performing URS and the following outcomes: stone-free rate, need for a second operation, and complications. Postoperative hospital stay was compared between patients receiving URS vs PCNL using Student's t -test. Results: One hundred twenty-five patients were included in this analysis. For patients with total stone burden exceeding 20 mm, those with more than three stones had roughly nine times the likelihood of undergoing URS over PCNL compared with patients with a single stone (adjusted odds ratio 9.21, confidence interval [95% CI] 2.55-40.58, p = 0.001). Stone-free rates, Clavien-Dindo scores, and frequency of second-look operations did not differ significantly between URS and PCNL patients. URS patients were discharged an average of 1.26 days earlier than patients who received PCNL (95% CI 0.72-1.81, p < 0.001). Discussion: Stone multiplicity strongly predicts which patients with stone burden >20 mm will undergo URS and who will undergo PCNL. These deviations from AUA guidelines do not appear to worsen patient outcomes. These results suggest that careful consideration of each patient may warrant deviation from guidelines.

Background: Racial disparities in guideline-based, appropriate treatment (ApT) may be a significant driving force for differences in survival for people with nonmetastatic muscle-invasive bladder cancer (MIBC). We hypothesize that receipt of ApT is influenced by factors such as race and socioeconomic status, irrespective of neighborhood-level differences in healthcare, variations in practice patterns, and clinical characteristics of patients with nonmetastatic MIBC., Methods: Within the National Cancer Database, we identified individuals diagnosed with MIBC between 2004 and 2013. Multivariable logistic regression and mixed effects modelling was used to examine predictors of ApT, clustered within institutions., Results: A total of 51,350 individuals had clinically staged nonmetastatic, lymph node-negative MIBC. Black individuals comprised 6.4% of the cohort. Mean age was 72.6 years (SD 11.6) with a male predominance (71.4%). Less than half received ApT (42.6%). Fewer black individuals received ApT compared with white individuals (37% vs. 43%, P < 0.001). When clustered by institution, the odds of ApT were 21% lower for black individuals [odds ratio (OR), 0.79; 95% confidence interval (CI), 0.73-0.87] compared with white individuals with nonmetastatic MIBC. When restricted to higher volume centers with more diverse populations, black individuals had 25% lower odds of ApT (OR, 0.75; 95% CI, 0.61-0.91; P < 0.01), compared with white counterparts., Conclusions: Racial disparities in treatment persisted after accounting for various clinical factors and social determinants of health. Future efforts should focus on addressing racial bias to improve disparities in bladder cancer treatment., Impact: If we are not delivering evidence-based care due to these biases (after accounting for access and biology), then it is expected that patients will experience inferior outcomes., (©2019 American Association for Cancer Research.)

- Abstract
Purpose: Cancer pathology findings are critical for many aspects of care but are often locked away as unstructured free text. Our objective was to develop a natural language processing (NLP) system to extract prostate pathology details from postoperative pathology reports and a parallel structured data entry process for use by urologists during routine documentation care and compare accuracy when compared with manual abstraction and concordance between NLP and clinician-entered approaches., Materials and Methods: From February 2016, clinicians used note templates with custom structured data elements (SDEs) during routine clinical care for men with prostate cancer. We also developed an NLP algorithm to parse radical prostatectomy pathology reports and extract structured data. We compared accuracy of clinician-entered SDEs and NLP-parsed data to manual abstraction as a gold standard and compared concordance (Cohen's κ) between approaches assuming no gold standard., Results: There were 523 patients with NLP-extracted data, 319 with SDE data, and 555 with manually abstracted data. For Gleason scores, NLP and clinician SDE accuracy was 95.6% and 95.8%, respectively, compared with manual abstraction, with concordance of 0.93 (95% CI, 0.89 to 0.98). For margin status, extracapsular extension, and seminal vesicle invasion, stage, and lymph node status, NLP accuracy was 94.8% to 100%, SDE accuracy was 87.7% to 100%, and concordance between NLP and SDE ranged from 0.92 to 1.0., Conclusion: We show that a real-world deployment of an NLP algorithm to extract pathology data and structured data entry by clinicians during routine clinical care in a busy clinical practice can generate accurate data when compared with manual abstraction for some, but not all, components of a prostate pathology report.

- Abstract
Introduction: Clinical T1 (cT1) bladder cancer is associated with high rates of recurrence, upstaging, and progression. Guidelines recommend that these patients be treated with adjuvant intravesical Bacillus Calmette-Guérin immunotherapy (BCG) or upfront radical cystectomy (RC). We analyzed the National Cancer Database (NCDB) to identify demographic and clinical determinants of guideline-based treatment (GBT) and RC., Patients and Methods: We identified 47,694 patients in the NCDB with cT1 bladder cancer diagnosed in 2004-2013. Those who did not receive any treatment or underwent primary chemotherapy were excluded. Mixed effects logistic regression adjusted for facility-level variation was used to identify factors associated with receipt of GBT., Results: The median age of the cohort was 72 years (interquartile range, 63-79). Of the patients, 22.4% were female, 5.1% were African American, and 2.7% had variant histology. Nearly one-third of patients received GBT: 11,453 (24%) were initially treated with BCG and 3320 (7%) were initially treated with RC. Recent year of diagnosis (odds ratio [OR], 1.67; 95% confidence interval [CI], 1.52-1.85; P < .001), treatment at an academic center (OR, 2.42; 95% CI, 2.27-2.59; P < .001), and private insurance status (OR, 1.41; 95% CI, 1.19-1.66; P < .001) were associated with increased odds of GBT. Of patients who received GBT, variant histology (OR, 5.89; 95% CI, 4.65-7.47; P < .001), and recent year of diagnosis (OR, 1.89; 95% CI, 1.50-2.39; P < .001) were associated with greater odds of RC., Conclusion: There is low treatment-guideline compliance for patients with cT1 disease. However, there appears to be a temporal trend toward increased use of GBT. Efforts should be made to understand why many cT1 bladder cancer patients do not receive GBT., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Objective: To explore whether there is an association between nonwhite race and frailty among older adults presenting to an academic nononcologic urology practice., Materials and Methods: This is a prospective study of individuals ages ≥65years presenting to a nononcologic urology practice between December 2015 and November 2016. All individuals had a Timed Up and Go Test (TUGT, where a slower TUGT time of ≥15 seconds is suggestive of frailty. TUGT times, race (white vs nonwhite), and other clinical data were extracted from the electronic medical record using direct queries. Multivariable logistic regression was used to identify the association between race and slower TUGT times while adjusting for age, gender, number of medications, body mass index, and number of urologic diagnoses., Results: Among the 1715 individuals in our cohort, 33.9% were of nonwhite race and 15.3% had TUGT ≥15 seconds. A higher percentage of nonwhite individuals had TUGT times ≥15 seconds compared to white individuals (23.6% vs 11.1%, P <.01). TUGT times ≥15 seconds were significantly associated with nonwhite race after adjusting for clinical factors (adjusted odds ratio 2.5, 95% confidence interval 1.8-3.3)., Conclusion: Among older adults presenting to an academic nononcologic urology practice, nonwhite race was associated with increased odds of frailty. A greater understanding of the relationship between race and frailty is needed to better address the needs of this vulnerable population., (Published by Elsevier Inc.)

- Abstract
Prostate cancer remains a leading cause of cancer-related death in men. Concurrently, the incidence of metastatic hormone-sensitive prostate cancer (mHSPC) at diagnosis has significantly risen as a result, in part, of recent advances in imaging. Given the increased utilization of prostate-specific membrane antigen-targeted positron emission tomography imaging and other modalities with improved accuracy in the detection of cancer, combined with changes in screening and other secular trends, more men get diagnosed at an oligometastatic stage in which timely treatment may improve survival. However, the optimal timing of initiation and the specific sequence of systemic agents are not yet clearly defined. Worldwide, both urologists and oncologists may primarily direct the medical management of mHSPC. This collaboration potentially invites differing treatment recommendations dependent upon the treating physician's medical specialty. Ideally, a shared decision-making approach incorporating multidisciplinary tumor board discussions and personalized analysis will provide personalized treatment recommendations to optimize the benefit for mHSPC patients. Here, we conducted a concise review and evaluation of existing literature, and provide one perspective on health care delivery for mHSPC worldwide. PATIENT SUMMARY: Given the improvement in imaging techniques and changes in screening practices, the incidence of metastatic hormone-sensitive prostate cancer will likely continue to rise. An early, multimodal treatment approach involving a multidisciplinary team is critical to delivering the best care to this patient population., (Copyright © 2018. Published by Elsevier B.V.)

- Abstract
Background: To compare the current racial/ethnic characteristics of practicing urologists to the U.S. population by American Urological Association (AUA) census geographic region., Methods: We compared urologist demographics from the 2014 AUA census to U.S. census data. Underrepresented in medicine (URM) status was defined as African-American (AA) or Hispanic race/ethnicity. Percent differences by AUA section were calculated by subtracting weighted frequencies of race/ethnicity for urologists from the general population. A negative percent difference denotes underrepresentation of urologists relative to the general population; positive percent difference denotes overrepresentation., Results: URM urologists (n=728, 6.5%) were younger and more often female than non-URM counterparts. Overall, AA and Hispanic urologists were underrepresented in most sections while Caucasian and Asian urologists were overrepresented. AA urologists were most underrepresented in the East South-Central section (-34.4%). Hispanic urologists (-38%) were most underrepresented in the Pacific section (-38%). Overall, the percentage of URM urologists, compared to non-URM urologists, were highest in the South Atlantic [37.9% (276/728) vs. 19.2% (1,984/10,319), P<0.01] and West South-Central [15.9% (116/728) vs. 11.1% (1,143/10,319), P<0.01]., Conclusions: URM urologists tend to be younger with a higher proportion of female providers, indicating a shift in race and gender. URM urologists were most underrepresented in the East South-Central and Pacific sections., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

- Abstract
Management of prostate cancer presents unique challenges because of the disease's variable natural history. Accurate risk stratification at the time of diagnosis in clinically localized disease is crucial in providing optimal counseling about management options. To accurately distinguish pathologically indolent tumors from aggressive disease, risk groups are no longer sufficient. Rather, multivariable prognostic models reflecting the complete information known at time of diagnosis offer improved accuracy and interpretability. After diagnosis, further testing with genomic assays or other biomarkers improves risk classification. These postdiagnostic risk assessment tools should not supplant shared decision making, but rather facilitate risk classification and enable more individualized care., (Copyright © 2017 Elsevier Inc.

- Abstract
We report the case of a 40-year-old woman with a history of uterine polyps and 3 months' worth of gross hematuria who was found to have a bladder mass on cystoscopy. Although this mass appeared benign visually, it demonstrated enhancement on axial imaging, with increased internal vascularity on Doppler ultrasound. A transurethral resection demonstrated bladder leiomyoma. This case increases the urologist's recognition of a well-described but previously underrepresented condition by showcasing its visual appearance on cystoscopy., (Published by Elsevier Inc.)

- Abstract
Purpose of Review: Active surveillance has become the recommended management strategy for most patients with low-risk prostate cancer (PCa), but whether surveillance criteria can be expanded without compromising oncologic outcomes is a matter of debate. Whereas there is essentially uniform consensus that those with low-risk disease can be safely managed with AS, those with intermediate-risk disease, younger men and African-American men are often excluded., Recent Findings: Outcome data for intermediate-risk patients managed by active surveillance demonstrate acceptable oncologic outcomes, but there is also evidence that such patients have higher rates of progression, adverse disease and metastatic disease. Studies evaluating the utility of quantitative Gleason grade, the use of biomarkers and multiparametric MRI are emerging and are likely to refine risk assessment. Literature describing the effects of young age on outcomes is lacking, but early data appear promising. Data on African-American men show varied results that are sometimes contradictory and further investigation is needed to elucidate the impact of race, independent of socioeconomic status., Summary: Patients with intermediate-risk PCa should not be excluded from active surveillance based on any single, borderline criterion; rather, treatment decisions should be based on the full clinical picture, and may be further refined by patient characteristics and adjunctive tools.

- Abstract
Purpose of Review: In 2012, the United States Preventive Services Task Force (USPSTF) issued a grade 'D' recommendation against the use of routine prostate-specific antigen (PSA)-based screening for any men. This recommendation reflects critical misinterpretations of the available evidence base regarding benefits and harms of PSA screening and has influenced the nationwide landscape of prostate cancer screening, diagnosis, and treatment., Recent Findings: Following the USPSTF recommendation, a substantial decline in PSA screening was noted for all age groups. Similarly, overall rates of prostate biopsy and prostate cancer incidence have significantly decreased with a shift toward higher grade and stage disease upon diagnosis. Concurrently, the incidence of metastatic prostate cancer has significantly risen in the United States. These trends are concerning particularly for the younger men with occult high-grade disease who are expected to benefit the most from early detection and definitive prostate cancer treatment., Summary: These emerging trends in PSA screening and prostate cancer incidence following the USPSTF recommendation may have significant public health implications. Due to the long natural history of the disease, a long-term follow-up is needed to provide a better understanding on the implications of such recommendations on disease progression and mortality rates in prostate cancer patients. The future of US screening policy should reflect a targeted 'smarter' screening strategy rather than dichotomizing the decision between 'screen all' or 'screen none'.

76. Ultrasound-Guided Renal Access and Tract Dilation.

- Abstract
Introduction: Ultrasound guidance is a unique alternative to fluoroscopy for percutaneous renal access. Besides being free of ionizing radiation exposure to the patient and intraoperative personnel, it offers several advantages including easier identification of the posterior renal calix and surrounding visceral structures. In this video, we demonstrate how ultrasound can be used to guide percutaneous nephrolithotomy (PCNL) in a step-by-step manner. Materials and Methods: From March to June 2016, 16 consecutive patients of age 18 and more with kidney or proximal ureteral stones underwent completely X-ray-free ultrasound-guided PCNL. No patients were excluded during the study period. Under general anesthesia, we place an externalized ureteral catheter through a flexible cystoscope with the patient in a frog-leg position. Retrograde saline injection is used to distend the collecting system only when needed. Then the patient is placed in a prone position. An ultrasound machine with a 3.5-MHz convex abdominal probe (Hitachi Aloka Medical America) is used to guide all steps of PCNL. For renal access, a longitudinal approach for needle insertion is usually chosen.
1 An 18-gauge Echotip needle (Cook Medical) is slowly advanced through the skin either in front of or behind the probe. On the ultrasound screen, the entire needle should be fully seen from skin to kidney and into the targeted calix. Entry into the collecting system is confirmed with either aspiration of urine or efflux of urine through the puncture needle. Then, the needle stylet is removed and a J-tip coaxial guidewire (Bard Medical) is inserted into the renal pelvis or down the proximal ureter under ultrasound monitoring. Gently moving the wire back and forth will help identify the location of the wire tip relative to the collecting system. Subsequently, the needle is withdrawn, a 1-cm skin incision is made surrounding the wire, and a 10F fascial dilator and a safety wire introducer are then passed over the wire. Although the wire appears with a bright echogenic signal, the dilator and the safety wire introducer are not echogenic. Their advancement over the wire can be observed ultrasonographically as they obscure the echogenic appearance of the wire. A second wire is subsequently advanced into the collecting system through the safety wire introducer. A high-pressure balloon dilator (BARD X-Force, Bard Medical) is then advanced into the collecting system over one of the wires. Because the deflated balloon tip can be difficult to identify on the ultrasound screen, the wire should be moved back and forth while passing the balloon and the operative surgeon should look for a change in the wire contour to judge where the balloon tip is relative to the wire. The placement of the tip of this balloon dilator is crucial, as ideally, it should be just within the collecting system of the target calix.2 A working tract is then dilated and the access sheath is carefully advanced until the back end of the balloon is seen. Then the balloon is withdrawn, an offset rigid nephroscope is inserted, and the stone is treated. Results: The mean age of patients was 48.8 ± 19.9 years. Forty-four percent of patients were male with a mean body mass index of 29.9 ± 7.9 kg/m2 and a mean stone size of 33.7 ± 15.0 mm. All procedures were effectively performed with ultrasound guidance with a mean operative time of 101.3 ± 32.2 minutes. Patients and intraoperative personnel were not exposed to any ionizing radiation during the surgery. No patients experienced any significant immediate postoperative complication. All patients were stone free (no visible stone fragments) based on intraoperative visual inspection using a flexible nephroscope and a renal ultrasound and KUB at 30 days after surgery, and no secondary procedures were required. Conclusions: Ultrasound guidance for renal access and tract dilation in prone PCNL is feasible and efficient. Although some situations such as obese patients or nondilated collecting system may present a challenge, the benefits of adopting this technique-namely eliminating ionizing radiation exposure and live imaging of anatomy surrounding the collecting system-provide value during PCNL.

- Abstract
Purpose: The high costs of fertility care may deter couples from seeking care. Urologists often are asked about the costs of these treatments. To our knowledge previous studies have not addressed the direct out-of-pocket costs to couples. We characterized these expenses in patients seeking fertility care., Materials and Methods: Couples were prospectively recruited from 8 community and academic reproductive endocrinology clinics. Each participating couple completed face-to-face or telephone interviews and cost diaries at study enrollment, and 4, 10 and 18 months of care. We determined overall out-of-pocket costs, in addition to relationships between out-of-pocket costs and treatment type, clinical outcomes and socioeconomic characteristics on multivariate linear regression analysis., Results: A total of 332 couples completed cost diaries and had data available on treatment and outcomes. Average age was 36.8 and 35.6 years in men and women, respectively. Of this cohort 19% received noncycle based therapy, 4% used ovulation induction medication only, 22% underwent intrauterine insemination and 55% underwent in vitro fertilization. The median overall out-of-pocket expense was $5,338 (IQR 1,197-19,840). Couples using medication only had the lowest median out-of-pocket expenses at $912 while those using in vitro fertilization had the highest at $19,234. After multivariate adjustment the out-of-pocket expense was not significantly associated with successful pregnancy. On multivariate analysis couples treated with in vitro fertilization spent an average of $15,435 more than those treated with intrauterine insemination. Couples spent about $6,955 for each additional in vitro fertilization cycle., Conclusions: These data provide real-world estimates of out-of-pocket costs, which can be used to help couples plan for expenses that they may incur with treatment., (Copyright © 2014 American Urological Association Education and Research, Inc.

- Abstract
Objective: To determine whether the presence of benign glandular tissue at the radical prostatectomy surgical margin is associated with technique (open radical prostatectomy [ORP] or robotic-assisted laparoscopic radical prostatectomy [RALRP]) and if benign glandular tissue increases the risk of biochemical recurrence., Methods: Surgical specimens from men with clinical T1-T2 disease who underwent radical prostatectomy (RP) between 2004 and 2010 were re-reviewed by a single uropathologist, examining all sections from the prostate apex and base for the presence of benign glandular tissue and tumor at the margin. Regression analysis was used to examine associations of benign glandular tissue with surgical approach and biochemical recurrence., Results: Of 934 cases reviewed, 431 were managed by ORP and 503 by RALRP with a median follow-up of 49 and 28 months, respectively. Overall, benign glandular tissue was found in 274 cases (29%): 98 (36%) at the apex, 138 (50%) at the base, and 38 (14%) at both. Compared with those who underwent ORP, patients who underwent RALRP had 3-fold greater odds of benign glandular tissue at the margin (P <.01), including significantly greater number of cases with benign glandular tissue at the base (P <.01). However, recurrence-free survival rates were similar between patients with and without benign glands at the surgical margin (BGM) regardless of surgical approach and across all clinical risk groups (log-rank P = .20)., Conclusion: Patients undergoing RALRP were more likely to have benign glandular tissue at the surgical margin. However, the presence of benign glandular tissue was not an independent risk factor for biochemical recurrence., (Published by Elsevier Inc.)

- Abstract
Selective phosphodiesterase type 5 inhibitors (PDE5Is) have revolutionized the treatment of erectile dysfunction (ED) in men. As an on-demand treatment, PDE5Is have excellent efficacy and safety in the treatment of ED due to a broad spectrum of etiologies. Nevertheless, these drugs do have side-effect profiles that are troublesome to some patients, eg, headache, dyspepsia, myalgia, etc. Furthermore, many patients and their partners dislike the necessity of on-demand treatment for ED, citing a desire for greater spontaneity with sexual interactions. In 2008, approximately 10 years after the release of the first commercially available PDE5I, a paradigm shift in the management of ED occurred with the approval of once-daily dose of tadalafil by the US Food and Drug Administration for the management of ED. The prolonged half-life of tadalafil lends itself well to this dosing regimen and conveys the advantage of separating medication from sexual interactions; lower dose therapy also carries the theoretical benefit of lower incidence of side effects. In this study, we review the current state of the art with respect to this new management strategy for ED, highlighting published reports of the efficacy and tolerability of the daily dose tadalafil regimen.
