PurposeOveractive bladder (OAB) syndrome significantly impairs quality of life, often necessitating pharmacological interventions with associated risks. The fragility of OAB trial outcomes, as measured by the fragility index (FI: smallest number of event changes to reverse statistical significance) and quotient (FQ: FI divided by total sample size expressed as a percentage), is critical yet unstudied.Materials and methodsWe conducted a systematic search for randomized controlled trials on OAB medications published between January 2000 and August 2023. Inclusion criteria were trials with two parallel arms reporting binary outcomes related to OAB medications. We extracted trial details, outcomes, and statistical tests employed. We calculated FI and FQ, analyzing associations with trial characteristics through linear regression.ResultsWe included 57 trials with a median sample size of 211 participants and a 12% median lost to follow-up. Most studies investigated anticholinergics (37/57, 65%). The median FI/FQ was 5/3.5%. Larger trials were less fragile (median FI 8; FQ 1.0%) compared to medium (FI: 4; FQ 2.5%) and small trials (FI: 4; FQ 8.3%). Double-blinded studies exhibited higher FQs (median 2.9%) than unblinded trials (6.7%). Primary and secondary outcomes had higher FIs (median 5 and 6, respectively) than adverse events (FI: 4). Each increase in 10 participants was associated with a +0.19 increase in FI (p

PurposeWe evaluate the efficacy and safety profiles of currently available conservative management options for penile and urethral lichen sclerosus.Materials and methodsA systematic review of existing literature on lichen sclerosus was conducted utilizing the PubMed, Embase, and Web of Science databases. References were assessed for relevance to nonsurgical management of male genital lichen sclerosus by title and abstract by 3 independent reviewers, then reviewed in full and in duplicate by 5 independent reviewers.ResultsSeventeen studies describing conservative management of histologically confirmed penile and urethral lichen sclerosus in male patients were included in the final review. We present available evidence supporting the use of 4 major treatment modalities represented in the existing literature: topical corticosteroids, tacrolimus, platelet-rich plasma, and CO2 laser. We also briefly discuss the limited studies on the use of oral acitretin and polydeoxyribonucleotide injections. Outcomes assessed include symptoms, clinical appearance, quality of life, sexual satisfaction, adverse effects, and long-term efficacy of treatment.ConclusionsTopical corticosteroids remain the mainstay of conservative management of penile and urethral lichen sclerosus, with current literature supporting the use of other therapies such as tacrolimus and platelet-rich plasma as alternatives or adjuvant treatments when escalation of treatment is necessary. Future research should further explore the efficacy and safety of newer therapies through additional controlled clinical trials in the targeted population.

ObjectiveTo characterize adverse events related to use of the perirectal spacing agent SpaceOAR, we examined the Manufacturer and User Facility Device Experience (MAUDE) database.MethodsThe MAUDE database was queried for "SpaceOAR" and "Augmenix" from June 2015 (when SpaceOAR was approved by the Food and Drug Administration) to October 2022. Reports were reviewed for adverse events (AEs), operative procedures performed because of the AE, and changes to the radiation plan. AEs were categorized using Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.ResultsSix hundred fifty-four reports were reviewed. Eighty-four were excluded and 4 reports reviewed 2 separate cases of SpaceOAR administration. Five hundred seventy-four cases were ultimately included. Three deaths were reported (0.5% of all AEs). One point six percent of cases represented CTCAE grade 4 injuries (life-threatening consequences; urgent intervention indicated), 15.9% grade 3 (severe but not immediately life-threatening; hospitalization), 24.2% grade 2 (moderate; local/noninvasive intervention), and 57% of events were CTCAE grade 1 (mild; asymptomatic or mild symptoms). Bowel diversion occurred in 29 cases (9%).ConclusionBoth asymptomatic (n = 311) and debilitating (n = 12) complications of SpaceOAR hydrogel use were identified. Death, gel embolization, anaphylaxis, rectal ulcerations, and infections requiring bowel or urinary diversions were among the complications reviewed. Providers should consider these potential complications before perirectal spacer administration and during patient counseling.

PurposeTo explore the differences of priapism events among a diverse cohort taking erectogenic medicines (i.e., phosphodiesterase type 5 inhibitors [PDE5i] and intracavernousal drugs).MethodsWe queried the World Health Organization global database of individual case safety reports (VigiBase) for records of the adverse drug reactions (ADR) with sildenafil, tadalafil, avanafil, vardenafil, papaverine, and alprostadil. Disproportionality analyses (case/non-case approach) were performed to assess the reporting odds ratio (ROR) of priapism reporting in PDE5i consumers compared to intracavernousal drug recipients.ResultsFrom a total of 133 819 ADR events for erectogenic medications, 632 were priapism (PDE5is: n = 550, 0.41%; intracavernousal drugs: n = 82, 9.92%). Priapism disproportionality signals from intracavernousal drugs were 25 times stronger than PDE5is (ROR = 34.7; confidence interval [CI] 95%: 27.12-43.94 vs. ROR = 1.38; 95% CI: 1.24-1.54). For all PDE5i agents, the 12-17 years age group had the highest ROR (9.49, 95% CI: 3.76-19.93) followed by 2-11 years (4.31, 95% CI: 1.57-9.4). Disproportionality signals for consumers under 18 for both all PDE5is as a whole (ROR = 4.57, 95% CI: 2.48-7.73) and sildenafil (ROR = 4.89, 95% CI: 2.51-8.62) were stronger than individuals 18 or older (ROR = 1.06, 95% CI: 0.93-1.21 and ROR = 1.08, 95% CI: 0.91-1.26, respectively).ConclusionsPDE5i use shows disproportionate priapism signals which are higher in young patients.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic made it necessary to practice social distancing and limited in-person encounters in health care. These restrictions created alternative opportunities to enhance patient access to care in the ambulatory setting. We hypothesized that by transforming clinics into centers that prioritize procedures and transitioning ambulatory appointments to telehealth, we could establish a secure, streamlined, and productive method for providing patient care. Methods: Clinic templates were restructured to allow the use of the physical space to perform procedure-based clinics exclusively, while switching to virtual telemedicine for all nonprocedural encounters. Staff members were given specific roles to support one of the patient care modalities for a given day (Procedures vs. Telehealth). Performance and patient satisfaction metrics were collected between two periods of time defined as P1 (February-June 2019) and P2 Post-COVID (February-June 2020) and compared. These served as proxies of periods when the clinic workflow and templates were structured in the traditional versus the emerging way. Statistical analysis was performed using bivariate analyses. Results: The percentage of procedures performed among all in-person visits were higher in P2 compared to P1 (45% vs. 29%, p < 0.001). Although total charges and relative value units were lower in P2, the overall revenue generated was higher compared to P1 ($4,597,846 vs. $4,517,427$, respectively). This increase in revenue was mainly driven by the higher relative income generated by procedures. Patient experience, reflected through patient-reported outcomes, was more favorable in P2 where patients seemed more likely to "Recommend this provider office" (90% vs. 85.7%, p = 0.01), report improved "Access overall" (56% vs. 49%, p = 0.02), and felt they were "Moving through your visit overall" (59% vs. 51%, p = 0.007). Conclusions: Our data suggest that reorganizing urology clinics into a space that is centered around outpatient procedures can represent a model that improves the patient's access to care and clinical experience, while simultaneously improving operational financial strength. This efficient care model could be considered for many practice settings and drive high-value outpatient care.

ObjectiveTo understand the effect of bicycle saddle shape and size on the pressure transmitted to the perineum, as prolonged perineal pressure and microtrauma amongst avid cyclists may increase the risk for complications following lower genitourinary surgery.MethodsWe tested five seats (Bontrager, Waterloo, WI) with varying levels of padding and morphology (comfort, fitness, fitness gel, race, and performance) for two different riders. The seats were installed on a Peloton stationary exercise bike (New York City, NY). Force measurements were performed using a 9833E-50 Large F-Socket Sensor (Tekscan, South Boston, MA). We measured total and perineal forces in three conditions at the same resistance: (a) at rest (not pedaling); (b) at 8mph; (c) at 15mph.ResultsSignificant differences across the bicycle seats were observed with fitness gel seats providing the lowest perineal pressure. In all measurements, perineal forces were significantly lower at 15mph compared to 8mph (P

Clinical Sciences ,Urology & Nephrology - Abstract
Haemorrhagic cystitis (HC) is characterised by persistent haematuria and lower urinary tract symptoms following radiotherapy or chemotherapy. Its pathogenesis is poorly understood but thought to be related to acrolein toxicity following chemotherapy or fibrosis/vascular remodelling after radiotherapy. There is no standard of care for patients with HC, although existing strategies including fulguration, hyperbaric oxygen therapy, botulinum toxin A, and other intravesical therapies have demonstrated short-term efficacy in cohort studies. Novel agents including liposomal tacrolimus are promising targets for further research. This review summarises the incidence and pathogenesis of HC as well as current evidence supporting its different management strategies.

PurposeTo investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management.MethodsWe used prospectively collected data as part of the Multi-institutional Genito-Urinary Trauma Study (MiGUTS). We included patients with grade V renal trauma according to the AAST Injury Scoring Scale 2018 update. All cases submitted by participating centers with radiology images available were independently reviewed to confirm renal trauma grade. Management was classified as expectant, conservative (minimally invasive, endoscopic or percutaneous procedures), or operative (renal-related surgery).ResultsEighty patients were included, 25 of whom had complete imaging and had independent confirmation of AAST grade V renal trauma. Median age was 35 years (Interquartile range (IQR) 25-50) and 23 (92%) had blunt trauma. Ten patients (40%) were managed operatively with nephrectomy. Conservative management was used in nine patients (36%) of which six received angioembolization and three had a stent or drainage tube placed. Expectant management was followed in six (24%) patients. Transfusion requirements were progressively higher with groups requiring more aggressive treatment, and injury characteristics differed significantly across management groups in terms of hematoma size and laceration size. Vascular contrast extravasation was more likely in operatively managed patients though a statistically significant association was not found.ConclusionSuccessful use of nonoperative management for grade V injuries is used for a substantial subset of patients. Lower transfusion requirement and less severe injury radiologic phenotype appear to be important characteristics delineating this group.

INTRODUCTION: To evaluate the clinical characteristics as well as the postoperative course of urolithiasis patients undergoing a ureteroscopy (URS) without stent placement. MATERIALS AND METHODS: This was a prospective case cohort study utilizing data collected in the Registry for Stones of the Kidney and Ureter (ReSKU) from a single institution between October 2015 and December 2020. We identified all consecutive patients undergoing URS for stone disease and analyzed data encompassing demographics, medical history, intra and postoperative characteristics, including complications and postoperative symptoms. Univariate and multivariate logistic regression analyses were performed based on the presence or absence of an indwelling ureteral stent. RESULTS: A total of 470 patients were included for analysis, 92 patients in the stentless group (19.5%). Factors associated with stentless ureteroscopy were a lower stone burden (p < 0.001), the pre-existence of a ureteral stent (37.4% vs. 27.9% p = 0.011), absence of an access sheath (14.6% vs. 69.5% p < 0.001), and a shorter operative time (31 vs. 58 min p < 0.001). Postoperative gross hematuria and lower urinary tract symptoms (LUTS) were reported less frequently in stentless patients (p = 0.02, p = 0.01, respectively). There was no difference in postoperative complications between both groups (15.2% vs. 12.0%, p = 0.385). On multivariate analysis, the risk of postoperative complications was associated with obesity, stone burden ≥ 1 cm, and positive preoperative urine culture. There was no patient who required emergent stent placement in the stentless group. CONCLUSION: Our data show that, in well selected patients, omitting ureteral stent placement after URS can decrease postoperative gross hematuria and LUTS without increasing postoperative complications.

Introduction: Outcomes after ultrasound-only percutaneous nephrolithotomy (PCNL), in which no fluoroscopy is used, are not well known. The goal of this study was to compare outcomes of ultrasound-only and fluoroscopy-directed PCNL. Materials and Methods: Prospectively collected data from the Registry for Stones of the Kidney and Ureter database were reviewed for all patients who underwent PCNL at one academic center from 2015 to 2021. Primary outcomes were complications and stone-free rates (no residual fragments ≥3 mm). Results: Of the 141 patients who underwent ultrasound-only PCNL and 147 who underwent fluoroscopy-directed PCNL, there was no difference in complication rates (15% vs 16%, p = 0.87) or stone-free status (71% vs 65%, p = 0.72), respectively. After adjusting for body mass index, American Society of Anesthesiologists (ASA), stone size, and stone complexity by Guy score, ultrasound-only PCNL was not associated with any increased odds of complications (odds ratio [OR] 0.7, 95% confidence interval [CI] 0.3-1.6, p = 0.41) or residual stone fragments ≥3 mm (OR 1.0, 95% CI 0.5-1.9, p = 0.972) compared with fluoroscopy-directed PCNL. Ultrasound-only PCNL was associated with shorter operative time (median 99.5 vs 126 minutes, p

ObjectiveTo systematically aggregate and summarize existing data on fistula prevalence among patients with a history of pelvic radiotherapy for prostate cancer.Materials and methodsWe queried PubMed, Embase, and Web of Science on October 7, 2020 for peer-reviewed publications pertaining to radiation-induced fistulas in the pelvis. For meta-analysis, we used the random-effects model. We used the I2 statistic to quantify heterogeneity and the Newcastle-Ottawa Scale to assess risk of bias.ResultsOur final meta-analysis included 6 cohort studies with a total of 7665 patients exposed to pelvic radiotherapy between 1967 and 2013. Median follow-up time was 35.5 months (IQR 33.5-57.5). Pooled prevalence of radiation-induced fistula across all 6 cohort studies was 0.2% (95% CI: 0.1-0.4, I2 = 0.000%, P < .608). In subgroup analysis, we did not detect significant heterogeneity in fistula prevalence in patients who were re-irradiated (0.3%, 95% CI: 0.1-0.4; P = .762) or patients on concurrent chemotherapy (0.4%, 95% CI: -0.3 -1.2; P = .664) compared to those receiving their first course of radiotherapy alone. No randomized controlled trials met inclusion criteria due to ambiguous and inconsistent reporting language for fistula occurrence.ConclusionThere is limited published literature reporting fistula as an adverse event of prostate cancer radiotherapy, especially in the medium and long-term period. Patients undergoing pelvic radiotherapy for prostate cancer appear at low short-term risk for developing fistulas. Adverse event reporting in randomized controlled trials merits greater granularity where fistulas should be reported with specificity rather than aggregating into broad categories of genitourinary or gastrointestinal adverse events.

Purpose: To explore the differences among erectile aids (i.e.,phosphodiesterase type 5 inhibitors [PDE5i] and intracavernousaldrugs) of the relative risk of priapism and identify age groups at risk.Methods: We queried the World Health Organization globaldatabase of individual case safety reports (VigiBase) for records of theADR with sildenafil, tadalafil, avanafil, vardenafil, papaverine, andalprostadil. Disproportionality analyses (case/non-case approach) wereperformed to assess the relative risk of priapism reporting in PDE5iconsumers compared to intracavernousal drug recipients.Results: From a total of 133,819 ADR events for erectogenicmedications, 632 were priapism (PDE5is: n=550, 0.41%; intracavernousaldrugs: n=82, 9.92%). We observed a strong signal for priapism inductionfor intracavernousal drugs than PDE5is (reporting odds ratio[ROR]=34.7; confidence interval [CI] 95%: 27.12 - 43.94vs. ROR= 1.38; CI 95%: 1.24 - 1.54). For all PDE5i agents, the12-17 years age group had the highest highest ROR (ROR=9.49, CI 95%:3.76 - 19.93) followed by 2-11 years (ROR=4.31, CI 95%: 1.57 - 9.4).Disproportionality signals for consumers under eighteen for both allPDE5is as a whole (ROR=4.57, CI 95%: 2.48 - 7.73) and sildenafil(ROR=4.89, CI 95%: 2.51 - 8.62) were significantly stronger thanindividuals eighteen or older (ROR=1.06, CI 95%: 0.93 - 1.21 andROR=1.08, CI 95%: 0.91 - 1.26, respectively). Conclusions:While the overall risk of priapism following the oral administration ofPDE5is is extremely low compared with intracavernousal remedies,adolescents are at a higher risk of priapism than older men.

BackgroundDespite their efficacy and general safety, rare but devastating adverse drug reactions have been associated with phosphodiesterase type 5 inhibitors.ObjectivesTo determine the safety profile of oral phosphodiesterase type 5 inhibitors with a particular focus on priapism and malignant melanoma.Materials and methodsIn this case-non-case study, we queried the individual case safety reports for phosphodiesterase type 5 inhibitors within the World Health Organization global database of individual case safety reports (VigiBase) between 1983 and 2021. We included all individual case safety reports for sildenafil, tadalafil, vardenafil, and avanafil in men. For comparison, we also extracted the safety data from the Food and Drug Administration trials for these drugs. We assessed the safety profile of phosphodiesterase type 5 inhibitors by disproportionality analysis by measuring reporting odds ratio for their most commonly reported adverse drug reactions, once for all phosphodiesterase type 5 inhibitor reports and once for reports of oral phosphodiesterase type 5 inhibitor use in adult men (≥18 years old) with sexual dysfunction.ResultsA total of 94,713 individual case safety reports for phosphodiesterase type 5 inhibitors were extracted. A total of 31,827 individual case safety reports were identified relating to adult men taking oral sildenafil, tadalafil, vardenafil, or avanafil for sexual dysfunction. The most common adverse drug reactions included poor drug efficacy (42.5%), headache (10.4% vs. 8.5%-27.6% [Food and Drug Administration]), abnormal vision (8.4% vs. ≤4.6% [Food and Drug Administration]), flushing (5.2% vs. 5.1%-16.5% [Food and Drug Administration]), and dyspepsia (4.2% vs. 3.4%-11.1% [Food and Drug Administration]). Priapism showed significant signals for sildenafil (reporting odds ratio = 13.81, 95% confidence interval: 11.75-16.24), tadalafil (reporting odds ratio = 14.54, 95% confidence interval: 11.56-18.06), and vardenafil (reporting odds ratio = 14.12, 95% confidence interval: 8.36-22.35). Comparing with other medications in VigiBase, sildenafil (reporting odds ratio = 8.73, 95% confidence interval: 7.63-9.99) and tadalafil (reporting odds ratio = 4.25, 95% confidence interval: 3.19-5.55) had significantly higher reporting odds ratios for malignant melanoma.ConclusionPhosphodiesterase type 5 inhibitors show significant signals correlating with priapism among a large international cohort. Further clinical study is needed to elucidate whether this is from proper or inappropriate use or other confounding conditions, as analysis of pharmacovigilance data does not allow for quantifying the clinical risk. Also, there appears to be a relationship between phosphodiesterase type 5 inhibitor use and malignant melanoma, which warrants additional study to better understand causation.

PurposeWe assessed the use of conservative management for American Association for the Surgery of Trauma grade V renal trauma in the National Trauma Databank.Materials and methodsWe used data of grade V renal trauma patients in the 2017-2019 National Trauma Databank. Conservative management was defined by the absence of surgical or procedural intervention except for ureteral stent or percutaneous drain placement. We initially analyzed patients who survived to final hospital discharge and reported the percent utilization of conservative management. We then repeated our analysis in the overall grade V population and in all those who did not die in the emergency department.ResultsOf 1,474 who survived to discharge, 557 (37.8%) patients were managed conservatively. In the adjusted analysis, penetrating trauma mechanism (OR 0.13, 95% CI 0.09-0.19, P < .001) and receiving transfusion (OR 0.22, 95% CI 0.17-0.29, P < .001) were associated with decreased odds of receiving conservative management. Overall, there were 1,919 patients with grade V injury, of whom 731 (38.1%) were managed conservatively. Mortality rate was 22.8% in those managed conservatively vs 23.8% in those who had intervention. After excluding 110 patients who died in the emergency department, there were 1,809 patients, of whom 625 (34.6%) were managed conservatively. Mortality rate was 22.6% in the operatively managed group and 10.9% in the conservatively managed group.ConclusionsA substantial portion of grade V renal trauma cases were managed successfully without intervention in the National Trauma Databank. Further research is needed to identify radiological phenotypes suitable for nonoperative management and to overcome possible renal trauma grade misclassification.

ObjectivesTo explore the association between perirenal fat thickness (PFT) and renal trauma grade. We hypothesise this association is related to a shock-absorbing effect of adiposity around the kidney.Patients and methodsWe identified all patients with renal trauma who arrived at the emergency department of a single trauma centre between 2014 and 2020. Radiology images were reviewed to measure the PFT around the uninjured kidney due to disrupted PFT around the traumatised kidney. Patients with no available images or penetrating trauma mechanism were excluded. Logistic regression was used to assess the relation between PFT and high-grade renal trauma (HGRT; defined as American Association for the Surgery of Trauma Renal Grade IV-V), adjusting for age, sex, and Injury Severity Scale (ISS).ResultsA total of 150 patients with renal trauma were included. The median (interquartile range) age was 38.5 (26-52) years and 106 (70.7%) were males. The PFT ranged between 2.1 and 50.1 mm, and 31 (20.7%) had HGRT. Interestingly, PFT only mildly correlated with body mass index (BMI; Pearson correlation coefficient 0.42, P

This cross-sectional analysis examined online US crowdfunding campaigns from 2010–2018. Campaigns including prostate, breast, bladder, kidney, cervical, uterine, ovarian, testicular, oral, and thyroid cancers were included. Multivariable modeling was utilized to examine predictive factors for successful campaigns. A total of 1830 online cancer campaigns were included in the final analysis. Breast cancer was estimated to be the most frequent online campaign type (n = 3682), followed by cervical (n = 492), kidney (n = 475), ovarian (n = 460), and prostate cancers (n = 382). Breast cancer campaigns generated the most total funding ($15.3 million). In adjusted models, breast cancers generated significantly more donations per campaign than any other cancer. There was no difference in the average amount of funds raised per campaign by most cancer types, except for thyroid (19.4% less than breast, p < 0.001). Friend-authored campaigns generated more funding than self- and family-authored. Male cancers are under-represented, and breast cancer campaigns are disproportionately over-represented in online medical crowdfunding and generate more donations than many other cancers. Gendered differences in cancer crowdfunding are likely multifactorial and may be influenced by social networks and public health campaigns.

IntroductionThe mean number of emergency department visits for all-cause traumas has declined significantly during the COVID-19 pandemic. We aim to identify how a global pandemic and social distancing could affect the trends and pattern of genitourinary traumas.MethodsWe queried the National Electronic Injury Surveillance System to obtain consumer product-related genitourinary injuries leading to emergency department visits. Using three key events in 2020, we divided the study period to three intervals: January 20, when the first COVID-19 case was confirmed in the United States; March 13, when a national state of emergency was declared; April 20, when Texas became the first state to start a phased reopening of economy. We compared the injury characteristics in 2020 to their identical intervals in 2019.ResultsDaily emergency department visits dropped significantly during the national lockdown (mean 131.5 vs. 78; Δ-40.7%; p

PurposeAlcohol intoxication is a known risk factor for motor vehicle collisions. We hypothesize ethanol intoxication increases the risk of bladder injury and surgical repair, especially at higher blood alcohol content levels.Materials and methodsWe identified all patients involved in motor vehicle collisions from the National Trauma Data Bank from 2017-2019. Patients were categorized into an intoxication and intoxication negative group. Variables collected included age, sex, blood alcohol content level, driver status, seat belt restraint use, nonalcoholic intoxication, pelvic fracture, and Injury Severity Scale. Primary outcome measures of bladder injury and bladder surgical repair were assessed and interaction with pelvic fracture and restraint use were measured.ResultsWe identified 594,484 patients and 97,831 (16.5%) had a positive alcohol screen. Patients in the intoxication group were more likely to be intoxicated with other substances (32.8% vs 14.6%, P < .001), have a bladder injury (1% vs 0.4%, P < .001) and receive bladder surgical repair (0.7% vs 0.15%, P < .001). Injury Severity Scale and pelvic fracture were statistically significant predictors of bladder injury. In adjusted analysis, higher blood alcohol content was associated with both outcomes. Above the legal limit, alcohol intoxication was more predictive of bladder surgical repair than pelvic fracture. The association of alcohol intoxication with both outcomes did not differ by pelvic fracture, but strengthened with seat belt use at higher intoxication levels.ConclusionsAlcohol intoxication is independently associated with increased risk of bladder injury and subsequent bladder surgical repair following motor vehicle collisions. Trauma providers should have a high index of suspicion for bladder injuries in alcohol intoxicated patients, particularly those using seat belt restraints.

PurposeWe aimed to provide a thorough comparative review of the available guidelines on the diagnosis, management, and follow-up for patients with posterior urethral stenosis by the American Urologic Association (2016), Société Internationale d'Urologie (2010), and European Urologic Association (2022).MethodsThe AUA, SIU, and EAU guidelines were evaluated for recommendations on the diagnosis, evaluation, and treatment of posterior urethral stenosis. We also included the EAU and AUA urologic trauma guidelines for the trauma-related stenosis. The level or strength of recommendations is included in case of disparity between the guidelines.ResultsThe three guidelines align considerably in recommendations provided for the diagnosis, management, and follow-up of patients with posterior urethral stenosis. SIU and EAU emphasize the role of repeat endoscopic treatment in guidelines compared to AUA.ConclusionThe preferred method to repair bulbo-membranous stricture/stenosis following radiation therapy remains an area of active interest, focusing on continence preservation. Additionally, there may be a role for advanced endoscopic treatments with or without adjunct therapies to manage even obliterated stenoses.

PurposeWe aimed to provide a detailed comparison between the American Urologic Association (AUA), Société Internationale d'Urologie (SIU), and the European Association of Urology (EAU) guidelines on the evaluation, management, and follow-up of the patients with anterior urethral stricture disease (USD).MethodsThe urethral stricture guidelines from SUI, AUA, and EAU were collected and evaluated regarding the recommendations on diagnosis, evaluation, and treatment of anterior USD. The strength of evidence for each statement was included and discussed when guidelines differed.ResultsWhile the guidelines remarkably align in terms of the diagnostic workup and follow-up, there is discordance in the management of anterior urethral strictures, specifically for the use of endoscopic treatment and stenting. Further, the EAU offers more comprehensive recommendations regarding urethroplasty techniques and patient follow-up. The EAU guidelines are the most recent and first to offer guidance for USD in transgender people and women.ConclusionReconstructive urology is a rapidly adapting field, and best practices change accordingly. Guideline statements have become more inclusive and expansive but will require further research to improve the level of evidence and continue to provide patients and providers with the best treatment plans.

PurposeWe describe the lived experience of adults with acquired buried penis (AABP) through thematic analysis of patient interviews. We examine the challenges that patients face and the impacts of surgery.Materials and methodsThis mixed-methods study utilized validated instruments and semi-structured interviews to capture pre- and postsurgical outcomes. Semi-structured interviews were conducted with open-ended questions to elicit the impact of AABP on a patient's quality of life in several domains including urinary function, sexual function, interpersonal relationships and mental health. Recruitment was completed once we achieved thematic saturation.ResultsTwenty patients participated in the study; 11 underwent surgical treatment for AABP. Semi-structured interviewee responses were coded into 12 different themes and 39 subthemes. The most common themes were problems with urinary (19/20, 95%) and sexual function (19/20, 95%). Most participants (16/20, 80%) reported negative impacts of AABP on social life. Interviewees struggled with relationships (8/20, 40%) and mental health (11/20, 55%), often avoiding romantic relationships and reporting fear of rejection with concomitant depression and/or anxiety. The majority (70%, 14/20) experienced difficulties accessing care. Among patients who underwent surgery, the majority discussed improvement in urinary and sexual function (82% [9/11] and 73% [8/11], respectively). Though weight gain was a precipitating factor, weight loss did not result in symptom improvement. Rather, in 4/20 (20%), weight loss made their condition worse.ConclusionsPatients living with AABP experience profound negative impacts on quality of life including their urinary and sexual function, social life and mental health. Many patients face issues with access to care.

IntroductionOur primary aim was to characterize eventual publication of presented American Urological Association (AUA) Annual Meeting oncology abstracts from 1997 to 2017. We hypothesized that the percentage of abstracts presented at the AUA Annual Meeting that became published peer-reviewed manuscripts increased over time.MethodsAUA Annual Meeting abstracts in "oncology" categories from 1997 to 2017 were identified. A random sample of 100 abstracts per year were assessed for publication. An abstract was considered "published" if 1) first and last author of the abstract were included on publication, 2) abstract and publication shared 1 conclusion, and 3) publication occurred from 1 year prior to the AUA Annual Meeting up to 10 years after. The search was conducted on PubMed® utilizing the MEDLINE® database.ResultsOver the 20-year observation period, 2,100 abstracts were reviewed and 56.3% were published.

PurposeTo evaluate the rate of perioperative venous thromboembolism (VTE) among patients undergoing common benign urologic reconstructive cases. We hypothesize that this rate will be lower than previously described.MethodsWe utilized the American College of Surgeons National Surgical Quality Improvement Project database from 2015 to 2019 to evaluate 30-day perioperative risk of VTE. Patients ≥ 18 years old undergoing benign urologic reconstructive cases were selected using Current Procedural Terminology (CPT) codes. Demographic, comorbidity, and operative variables were captured. The primary outcome was VTE within the 30-day postoperative period.ResultsWe identified 8467 patients who met inclusion criteria. The majority of patients were male (> 95%) with an average age of 65 and BMI of 29.6. There were 23 VTE events (0.27%) within the 30-day perioperative period. Fourteen (14/59) procedures had a perioperative VTE. Many of the traditional factors for VTE including operative time and obesity significantly increased risk of VTE in univariate analysis. In multivariate analysis, only BMI (OR 1.09; 95% CI 1.01-1.12) and inpatient status (OR 4.42; 95% CI 1.9-10.2) were correlated with increased perioperative VTE.ConclusionThe rate of VTE among patients undergoing benign urologic reconstructive cases is low. Providers should continue to have high index of suspicion particularly for inpatients with high BMI in addition to other known risk factors for VTE.

BackgroundCrowdfunding is increasingly used to offset the financial burdens of illness and health care. In the era of the COVID-19 pandemic and associated infodemic, the role of crowdfunding to support controversial COVID-19 stances is unknown.ObjectiveWe sought to examine COVID-19-related crowdfunding focusing on the funding of alternative treatments not endorsed by major medical entities, including campaigns with an explicit antivaccine, antimask, or antihealth care stances.MethodsWe performed a cross-sectional analysis of GoFundMe campaigns for individuals requesting donations for COVID-19 relief. Campaigns were identified by key word and manual review to categorize campaigns into "Traditional treatments," "Alternative treatments," "Business-related," "Mandate," "First Response," and "General." For each campaign, we extracted basic narrative, engagement, and financial variables. Among those that were manually reviewed, the additional variables of "mandate type," "mandate stance," and presence of COVID-19 misinformation within the campaign narrative were also included. COVID-19 misinformation was defined as "false or misleading statements," where cited evidence could be provided to refute the claim. Descriptive statistics were used to characterize the study cohort.ResultsA total of 30,368 campaigns met the criteria for final analysis. After manual review, we identified 53 campaigns (0.17%) seeking funding for alternative medical treatment for COVID-19, including popularized treatments such as ivermectin (n=14, 26%), hydroxychloroquine (n=6, 11%), and vitamin D (n=4, 7.5%). Moreover, 23 (43%) of the 53 campaigns seeking support for alternative treatments contained COVID-19 misinformation. There were 80 campaigns that opposed mandating masks or vaccination, 48 (60%) of which contained COVID-19 misinformation. Alternative treatment campaigns had a lower median amount raised (US $1135) compared to traditional (US $2828) treatments (P

PurposeAlthough circumcision is the most commonly performed surgery in males, less is known about the incidence and indications of adult circumcision. In this study, we aim to present the incidence of adult circumcision across the United States.MethodsUsing IBM MarketScan® Commercial Database from 2015 to 2018, we obtained claims for circumcision in men between 18 and 64 years of age. We calculated the incidence of adult circumcision over the study period and across the United States. We also collected data on indications for surgery using International Classification of Diseases codes.ResultsWe identified a total of 12,298 claims for adult circumcisions. The mean age was 39 (±12.9) years. The average incidence rates remained relatively constant from 98.1 per 100,000 person-years in 2015 to 98.2 per 100,000 person-years in 2018 (Δ+0.1%). The age-standardized incidence rates varied significantly across the United States (from 0 to 194.8 per 100,000 person-years) with South Dakota having the highest rate. The most common indications for adult circumcision were phimosis (52.5%), routine/ritual circumcision (28.7%), phimosis + balanitis/balanoposthitis (6.8%), balanitis (3.8%) and balanoposthitis (2.6%), and significantly varied by age groups.ConclusionThis study suggested a wide geographic variation in rates of adult circumcision between states with highest incidences in the Northeast United States. Future studies can identify the underlying causes for the observed variations.

BackgroundThe obesity paradox has been recently demonstrated in trauma patients, where improved survival was associated with overweight and obese patients compared to patients with normal weight, despite increased morbidity. Little is known whether this effect is mediated by lower injury severity. We aim to explore the association between body mass index (BMI) and renal trauma injury grade, morbidity, and in-hospital mortality.MethodsA retrospective cohort of adults with renal trauma was conducted using 2013-2016 National Trauma Data Bank. Multiple regression analyses were used to assess outcomes of interest across BMI categories with normal weight as reference, while adjusting for relevant covariates including kidney injury grade.ResultsWe analyzed 15181 renal injuries. Increasing BMI above normal progressively decreased the risk of high-grade renal trauma (HGRT). Subgroup analysis showed that this relationship was maintained in blunt injury, but there was no association in penetrating injury. Overweight (OR 1.02, CI 0.83-1.25, p = 0.841), class I (OR 0.92, CI 0.71-1.19, p = 0.524), and class II (OR 1.38, CI 0.99-1.91, p = 0.053) obesity were not protective against mortality, whereas class III obesity (OR 1.46, CI 1.03-2.06, p = 0.034) increased mortality odds. Increasing BMI by category was associated with a stepwise increase in odds of acute kidney injury, cardiovascular events, total hospital length of stay (LOS), intensive care unit LOS, and ventilator days.ConclusionsIncreasing BMI was associated with decreased risk of HGRT in blunt trauma. Overweight and obesity were associated with increased morbidity but not with a protective effect on mortality. The obesity paradox does not exist in kidney trauma when injury grade is accounted for.

ObjectiveTo assess provider and practice characteristics that drive opioid prescription behavior using the American Urological Association census data.MethodsStratified weighted analysis using 1,157 census samples was performed to represent 12,660 urologists who practiced in the United States in 2018. We compared urologists according to their opioid prescription patterns to evaluate factors and motivations behind opioid use in the post-operative setting.ResultsOverall, 11,205 (88.5%) urologists prescribe opioids in the post-operative setting. The presence of procedure-specific institutional prescribing guidelines was associated with a greater tendency to prescribe ≤10 pills, and lesser tendency to prescribe 11 to 49 and ≥50 tablets following open abdominal (P = .003), laparoscopic (P < .001), scrotal (P < .001), and endoscopic surgeries (P < .001). The presence of institutional prescribing guidelines was associated with decreasing opioid prescriptions over a three-year period whereas not having guidelines was associated with an unchanged prescription practice over time. Basing current prescriptions on what was given to prior patients was reported by 85% and was more likely to result in an unchanged amount of prescriptions over time (29.2% vs 13.3%, P = .007). Motivations to avoid patient phone calls were reported by 23.8% and were more likely to increase the opioids provided within the next 3 years (3.2% vs 0.1%, P < .001).ConclusionPractitioners who endorsed using institutional guidelines prescribed fewer opioids following all types of surgery and were more likely to decrease their prescription behavior over time. This data supports continued efforts to provide urologists with more evidence-based guidance on best practice opioid prescribing in the future.

AimsTreatment for urinary incontinence (UI) includes pelvic floor muscle training (PFMT). There is limited data appraising the characteristics of PFMT devices. We aimed to ascertain the primary use, strengths and weaknesses of PFMT devices available online, through evaluation of consumer reviews.MethodsWe performed an analysis of PFMT devices on Amazon.com. Four key device categories were recognized. Reviews from the five most frequently-reviewed products per category were analyzed (n = 20). W characterized device use, strengths and weaknesses using thematic analysis.ResultsWe evaluated 2574 PFMT device reviews including 1168 vibrating Kegel balls, 750 non-vibrating Kegel balls, 411 pelvic floor or thigh exercisers, and 245 electric probes. Non-vibrating Kegel balls were rated highest (4.6/5 stars), followed by vibrating Kegel balls, electric probes and pelvic floor or thigh exercisers (4.4/5, 4.1/5, and 3.8/5 stars, respectively). Most reviews were positive (77%) or negative (16%) with few neutral (7%). While all were marketed to treat UI, most reviews did not mention the intended use. Vibrating and non-vibrating Kegel balls and electric probes were most likely to be used for UI, and pelvic floor or thigh exercisers for toning. Some used non-vibrating and vibrating Kegel balls for sexual function. Electric probes were the most beneficial device for incontinence control (27%, 67/245). Twenty-five percent of all product reviews praised device ease of use and good quality or design. A minority of reviewers found products difficult to use, of poor quality or design and uncomfortable.ConclusionConsumers utilized online PFMT devices for multiple purposes, including UI, toning and sexual function. Reviewers generally praised PFMT products, particularly electric probes for UI.

Purpose: We compare Fournier gangrene in female and male patients and identify mortality-associated characteristics in both. Materials and Methods: We used National Inpatient Sample data (2016-2020) to identify Fournier gangrene cases and extracted demographic, comorbidity, and procedural variables. Multivariable regression models were used to identify mortality risk factors for both cohorts. Results: We identified 2875 female (31%) and 6451 male patients (69%) with Fournier gangrene corresponding to an estimated 14,375 (95% CI, 13,784-14,966) and 32,255 (95% CI, 31,390-33,120) cases, respectively. Female patients were more likely to die than male patients (7.1% vs 5.7%, P <.0001, respectively). The median incidence rates were 1.7 (interquartile range, 1.5-1.8) and 4 (interquartile range, 3.6-4.3) cases per 100,000 person-years for female and male patients, respectively. Female patients had higher median age, longer hospital stays, more charges, procedures, and fecal diversion rates, but lower routine discharges than male patients (P <.05). Non-White female patients had increased mortality odds compared with White female patients (odds ratio [OR], 1.49; 95% CI, 1.07-2.07; P =.019). Prolonged interval until initial perineal debridement correlated with higher mortality odds in both female and male patients (OR, 1.02; 95% CI, 1-1.04; P =.034 vs OR, 1.03; 95% CI, 1.01-1.05; P <.0001). Diabetes lowered mortality odds in female and male patients (OR, 0.68; 95% CI, 0.47-0.99; P =.046 vs OR, 0.54; 95% CI, 0.41-0.7; P <.0001). Conclusions: In female patients, Fournier gangrene incidence surpasses previous reports, with slightly worse outcomes compared with male patients, emphasizing the need for precise clinical assessment and early intensive interventions.
