Revisiting Fournier's Gangrene: A Contemporary Epidemiological Perspective vs. Perineal Cellulitis.

INTRODUCTION: We conducted a population-based analysis of Fournier's gangrene to compare risk factors and mortality with perineal cellulitis. METHODS: We analyzed National Inpatient Sample data (2016-2020) to identify Fournier's gangrene and perineal cellulitis cases. Demographic, comorbidity, and procedural data were extracted. Logistic models assessed risk factors for Fournier's gangrene diagnosis and mortality. RESULTS: A total of 73,472 cellulitis and 9,326 Fournier's gangrene cases were identified corresponding to 74,905 (range 63,050-79,165) and 9,115 (range 7,925-11,080) median yearly weighted cases, respectively. Fournier's gangrene diagnosis vs cellulitis was positively associated with Native American race (OR 1.46, 95% CI 1.19-1.79), weekend (OR 1.12, 95% CI 1.06-1.18) or December (OR 1.33, 95% CI 1.22-1.44) admissions, diabetes mellitus (OR 2.51, 95% CI 2.38-2.64), and malignancy (OR 2.29, 95% CI 2.07-2.54). Conversely, Hispanic (OR 0.79, 95% CI 0.74-0.85), Asian/Pacific Islander races (OR 0.83, 95% CI 0.69-0.99), and the highest household income quartile (OR 0.84, 95% CI 0.78-0.90) were linked to a reduced likelihood of Fournier's gangrene diagnosis. Elevated mortality risks were observed with female gender (OR 1.33, 95% CI 1.08-1.63), Native American ethnicity (OR 2.29, 95% CI 1.14-4.57), and procedural frequency (OR 1.27, 95% CI 1.24-1.3) among Fournier's gangrene cases. CONCLUSIONS: Various patient and clinical factors are linked to the development and mortality of Fournier's gangrene compared to perineal cellulitis. Improved access to care and understanding of Fournier's gangrene can enhance patient outcomes.

Higher Morbidity and Mortality in Females With Fournier's Gangrene Compared to Males: Insights From National Inpatient Sample Data.

PURPOSE: To compare Fournier's gangrene in female and male patients, and identify mortality-associated characteristics in both. MATERIALS AND METHODS: We employed National Inpatient Sample data (2016-2020) to identify Fournier's gangrene cases and extracted demographic, comorbidity, and procedural variables. Multivariable regression models were utilized to identify mortality risk factors for both cohorts. RESULTS: We identified 2875 females (31%) and 6451 males (69%) with Fournier's gangrene corresponding to an estimated 14,375 (95% CI 13,784-14,966) and 32,255 (95% CI 31,390-33,120) cases, respectively. Females were more likely to die than males (7.1% vs 5.7%, P < .0001, respectively). Median incidence rates were 1.7 (IQR 1.5-1.8) and 4 (IQR 3.6-4.3) cases per 100,000 person-years for females and males, respectively. Females had higher median age, longer hospital stays, more charges, procedures, and fecal diversion rates, but lower routine discharges than males (P < .05). Non-White females had increased mortality odds compared to White females (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 females and males (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 females and males (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 females, Fournier's gangrene incidence surpasses previous reports, with slightly worse outcomes compared to males, emphasizing the need for precise clinical assessment and early intensive interventions.

The Epidemiology of Genitourinary Self-Inflicted Injuries: Analysis of the National Trauma Databank.

OBJECTIVES: To provide insight into the epidemiologic characteristics and trends of genitourinary (GU) self-inflicted injury (SII). METHODS: We used data from the National Trauma Databank between 2017-2020. We described the characteristics of GU SII cases based on injured organ and then compared male and female injuries. RESULTS: We identified 56,463 patients with SII, of which 1,508 (2.7%) had GU involvement. Most cases were male patients (77.3%) and white (70.6%). Median age was 35 years (IQR 26 - 50). The most commonly injured GU organs was kidney (43.4%), followed by scrotum / testes (22.5%), and penis (18.2%). Most cases (89.9%) represented a single-organ injury whereas 10.1% had two or more GU organs injured. Seventy-three of those with kidney injuries (11.2%) underwent nephrectomy. Only one patient performing GU SII had a diagnosis code for transsexualism but the majority (82.2%) suffered from pre-existing conditions of which 20.5% had three or more comorbidities. More than half the population (54.9%) had preexisting diagnosed mental or personality disorder. A non-GU co-injury was present in most cases (70.8%), most commonly affecting another abdominal organ (44.3%) or fractures (41.3%). A positive drug screen was found in 30.7% of cases. Most patients survived though 15.4% died. 94% of fatal cases had a concomitant non-GU injury. CONCLUSIONS: GU injuries account for 2.6% of all SII. These patients are often young white males with known mental or personality disorders. Kidneys were most common injuried and mortality was highest in cases of kidney and bladder injuries with multi-organ trauma involving non-GU organs.

Ejaculatory function after radiotherapy for prostate cancer: a systematic review and meta-analysis.

BACKGROUND: Scant data exists on the impacts of prostate radiation on ejaculatory function. We performed a systematic review and meta-analysis to assess ejaculatory outcomes in men after prostate radiation. METHODS: We queried PubMed, Embase, and Web of Science to identify 17 articles assessing ejaculatory function post-radiation. The primary outcome was anejaculation rate and secondary outcomes included ejaculatory volume (EV), ejaculatory discomfort, and mean decline in ejaculatory function scores (EFS). We assessed study quality with the Newcastle-Ottawa scale. We calculated pooled proportions using inverse variance and random effects models. RESULTS: We identified 17 observational studies with 2156 patients reporting ejaculatory profiles post-radiation. Seven studies utilized external beam radiation therapy, 7 brachytherapy, 1 stereotactic RT and 2 utilized either external or brachytherapy. Ten studies reported an anejaculation rate. Pooled proportion of patients having anejaculation, decreased EV and EjD were 18% (95% CI, 11-36%), 85% (95% CI, 81-89%) and 24% (95% CI, 16-35%), respectively. Five studies reported decline in EFS post-radiation. CONCLUSIONS: Patients receiving radiation treatment may experience significant changes in their ejaculation, such as the absence of ejaculation, reduced EV, and EjD. It is important to counsel them about these potential side effects.

The Impact of Social Deprivation on Anterior Urethral Stricture Recurrence After Urethroplasty - A Trauma and Urologic Reconstructive Network of Surgeons (TURNS) Analysis.

INTRODUCTION AND OBJECTIVES: Several factors influence recurrence after urethral stricture repair. The impact of socioeconomic factors on stricture recurrence after urethroplasty is poorly understood. This study aims to assess the impact that social deprivation, an area-level measure of disadvantage, has on urethral stricture recurrence after urethroplasty. METHODS: We performed a retrospective review of patients undergoing urethral reconstruction by surgeons participating in a collaborative research group. Home zip code was used to calculate Social Deprivation Indices (SDI; 0-100), which quantifies the level of disadvantage across several sociodemographic domains collected in the American Community Survey. Patients without zip code data were excluded from the analysis. The Cox Proportional Hazards model was used to study the association between SDI and the hazard of functional recurrence, adjusting for stricture characteristics as well as age and body mass index. RESULTS: Median age was 46.0 years with a median follow up of 367 days for the 1452 men included in the study. Patients in the fourth SDI quartile (worst social deprivation) were more likely to be active smokers with traumatic and infectious strictures compared to the first SDI quartile. Patients in the fourth SDI quartile had 1.64 times the unadjusted hazard of functional stricture recurrence vs patients in the first SDI quartile (95% CI 1.04-2.59). Compared to anastomotic ± excision, substitution only repair had 1.90 times the unadjusted hazard of recurrence. The adjusted hazard of recurrence was 1.08 per 10-point increase in SDI (95% CI 1.01-1.15, P = .027). CONCLUSIONS: Patient social deprivation identifies those at higher risk for functional recurrence after anterior urethral stricture repair, offering an opportunity for preoperative counseling and postoperative surveillance. Addressing these social determinants of health can potentially improve outcomes in reconstructive surgery.

Injuries With Electric vs Conventional Scooters and Bicycles.

Importance: Micromobility, the use of small vehicles (primarily scooters and bicycles), has become a standard transportation method in the US. Despite broad adoption of electric micromobility vehicles, there is a paucity of data regarding the injury profiles of these vehicles, particularly in the US. Objective: To characterize micromobility injury trends in the US, identify demographic characteristic differences in users of electric and conventional vehicles, and identify factors associated with hospitalization. Design, Setting, and Participants: This cross-sectional study queried the National Electronic Injury Surveillance System, a comprehensive database that collates injury data associated with consumer products from emergency departments across the US to provide national estimates, from calendar year 2017 to 2022. Data on micromobility vehicle injuries (bicycles, scooters, electric bicycles [e-bicycles], and electric scooters [e-scooters]) were obtained. Main Outcomes and Measures: Trends in injury and hospitalization counts, injury characteristics, and factors associated with hospitalization. Results: From 2017 to 2022, the US recorded 2 499 843 bicycle (95% CI, 1 948 539-3 051 147), 304 783 scooter (95% CI, 232 466-377 099), 45 586 e-bicycle (95% CI, 17 684-73 488), and 189 517 e-scooter (95% CI, 126 101-252 932) injuries. The median age of the riders was 28 (IQR, 12-51) years; 72% were male, 1.5% Asian, 13% Black, 12% Hispanic, and 49% White. Annual e-bicycle and e-scooter injuries increased from 751 (95% CI, 0-1586) to 23 493 (95% CI, 11 043-35 944) and injuries increased from 8566 (95% CI, 5522-11 611) to 56 847 (95% CI, 39 673-74 022). Compared with conventional vehicles, electric vehicle accidents involved older individuals (median age, 31 vs 27 years; P < .001) and a higher proportion of Black riders (25% vs 12%; P < .001). Helmet use was less in electric vehicle incidents compared with conventional vehicles (43% vs 52%; P = .02), and injuries were more common in urban settings (83% vs 71%; P = .008). Age-adjusted odds of hospitalization among all Black individuals compared with White individuals was 0.76 (95% CI, 0.59-0.98; P = .04). Conclusions and Relevance: In this cross-sectional study of micromobility vehicles, an increased number of injuries and hospitalizations was observed with electric vehicles compared with conventional vehicles from 2017 to 2022. These findings suggest the need for change in educational policies, infrastructure, and law to recenter on safety with the use of micromobility vehicles.

Renal Autotransplantation: Association Between Preoperative Disease Duration and Surgical Outcomes.

OBJECTIVE: To determine whether early versus delayed autotransplantation are associated with adverse outcomes in patients undergoing renal autotransplantation. METHODS: Patients who underwent renal autotransplantation from June 2012 to September 2022 were divided into 2 groups based on timing of autotransplant in relation to initial intervention or diagnosis (early cohort: ≤1-year; delayed cohort: >1-year). Primary outcomes were perioperative complications, aborted surgery, renal function (glomerular filtration rate [GFR]), and postoperative complications at most recent follow-up. RESULTS: Autotransplantation patients (N = 72) were predominantly female (68%) and White (54%), with a median age of 49 years. Ninety percentage of patients had undergone previous interventions, including stenting (40%) and nephrostomy tubes (49%), primarily for obstruction (64%). Early versus delayed cohorts had median preoperative disease durations of 143 (IQR 83-222) versus 673 days (IQR 529-1703, P <.001), with similar median follow-up times (879 vs 818 days, P = .8). Groups were similar in demographics and comorbidities. There were no significant differences in rates of aborted surgery (15% vs 4.2%, P = .3), perioperative complications (15% vs 17%, P > .9), long-term complications (49% vs 48%, P > .9), or changes in GFR (median change +3 vs +4, P = .7). Outcomes were comparable across preoperative disease durations ranging from 6 to 24 months. These findings were confirmed following adjustments for sex, body mass index, American Society of Anesthesiologists classification, race, preoperative creatinine levels, laterality, gastroesophageal reflux disease, diabetes, hypertension, nephrolithiasis, hyperlipidemia, history of colon surgery, urologic surgery, abdominal surgery, and prior interventions in separate logistic models. CONCLUSION: Disease duration before autotransplantation does not influence outcomes, offering reassurance for clinical decision-making in complex cases.

Patient Perception of Physician Reimbursement by Medicare for Artificial Urinary Sphincter Placement.

INTRODUCTION: Patient perceptions of physician reimbursement commonly differ from actual reimbursement. This study aims to improve health care cost transparency and trust between patients, physicians, and the health care system by evaluating patient perceptions of Medicare reimbursement for artificial urinary sphincter (AUS) placement. METHODS: We identified patients who underwent AUS placement at a single institution from 2014 to 2023. After obtaining informed consent, we administered a telephone survey to ask patients about their perceptions of Medicare reimbursement for AUS surgery and the amount they felt the physician should be compensated. RESULTS: Sixty-four patients were enrolled and completed the survey. On average, patients estimated Medicare physician reimbursement to be $18,920, 25 times the actual average procedure reimbursement. Once informed that the actual amount was $757.52, 97% of respondents felt that the reimbursement was "somewhat lower" (13%) or "much lower" (84%) than what they considered fair. The average amount that patients felt the physician should be paid was $8,844, 12 times the actual average procedure reimbursement. Fifty-four percent of patients estimated their physician's reimbursement to be higher than what they later reported as being "fair," representing a presurvey belief that their physician was overpaid. CONCLUSIONS: Patient perceptions of physician reimbursement for AUS are vastly different than the actual amount paid. The discordance between patient perception and actual reimbursement could impact how patients view health care costs and the relationship with their provider.

Case presentation and review of renal autotransplantation for nutcracker syndrome.

Nutcracker Syndrome (NCS) is characterized by entrapment of the left renal vein, leading hematuria, flank pain, and proteinuria. We evaluated the efficacy of renal autotransplantation as a curative treatment for NCS through a review and case report. 55 patients from 18 studies were analyzed, with a combined 91% success rate of symptom resolution or improvement post-autotransplantation. In our case report, a 25-year-old man with severe NCS received laparoscopic nephrectomy and autotransplant, resulting in symptom resolution at 3.1 years follow up. Further research should confirm these findings and refine patient selection criteria and surgical techniques.

Fragility of overactive bladder medication clinical trials: A systematic review.

PURPOSE: Overactive 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 METHODS: We 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. RESULTS: We 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 < 0.001). CONCLUSIONS: A change in outcome for a median of five participants, or 3.5% of the total sample size, could reverse the direction of statistical significance in OAB trials. Studies with larger sample sizes and efficacy outcomes from blinded trials were less fragile.

Electric Bicycle Injuries and Hospitalizations.

This cross-sectional study investigates injury trends associated with electric bicycles in the US from 2017 to 2022.

Real-World Complications of the SpaceOAR Hydrogel Spacer: A Review of the Manufacturer and User Facility Device Experience Database.

OBJECTIVE: To characterize adverse events related to use of the perirectal spacing agent SpaceOAR, we examined the Manufacturer and User Facility Device Experience (MAUDE) database. METHODS: The 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. RESULTS: Six 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%). CONCLUSION: Both 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.

Haemorrhagic cystitis: a review of management strategies and emerging treatments.

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.

Cxbladder Monitor testing to reduce cystoscopy frequency in patients with bladder cancer.

PURPOSE: Bladder cancer surveillance is associated with high costs and patient burden. CxMonitor (CxM), a home urine test, allows patients to skip their scheduled surveillance cystoscopy if CxM-negative indicating a low probability of cancer presence. We present outcomes from a prospective multi-institutional study of CxM to reduce surveillance frequency during the coronavirus pandemic. MATERIALS AND METHODS: Eligible patients due for cystoscopy from March-June 2020 were offered CxM and skipped their scheduled cystoscopy if CxM-negative. CxM-positive patients came for immediate cystoscopy. The primary outcome was safety of CxM-based management, assessed by frequency of skipped cystoscopies and detection of cancer at immediate or next cystoscopy. Patients were surveyed on satisfaction and costs. RESULTS: During the study period, 92 patients received CxM and did not differ in demographics nor history of smoking/radiation between sites. 9 of 24 (37.5%) CxM-positive patients had 1 T0, 2 Ta, 2 Tis, 2 T2, and 1 Upper tract urothelial carcinoma (UTUC) on immediate cystoscopy and subsequent evaluation. 66 CxM-negative patients skipped cystoscopy, and none had findings on follow-up cystoscopy requiring biopsy. Six of these patients did not attend follow-up, 4 elected to undergo additional CxM instead of cystoscopy, 2 stopped surveillance, and 2 died of unrelated causes. CxM-negative and positive patients did not differ in demographics, cancer history, initial tumor grade/stage, AUA risk group, or number of prior recurrences. Median satisfaction (5/5, IQR 4-5) and costs (26/33, 78.8% no out-of-pocket costs) were favorable. CONCLUSIONS: CxM safely reduces frequency of surveillance cystoscopy in real-world settings and appears acceptable to patients as an at-home test.

Radiation-induced Fistulas in Patients With Prior Pelvic Radiotherapy for Prostate Cancer: A Systematic Review and Meta-analysis.

OBJECTIVE: To systematically aggregate and summarize existing data on fistula prevalence among patients with a history of pelvic radiotherapy for prostate cancer. MATERIALS AND METHODS: We 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. RESULTS: Our 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. CONCLUSION: There 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.

Thematic analysis of the psycho-sexual symptoms in patients with Peyronie's disease present on online forums.

Peyronie's disease (PD) is a fibrotic disorder of the tunica albuginea that may result in penile deformity, pain, a palpable plaque, and erectile dysfunction. In order to understand the psycho-sexual impacts of PD on patients and their partners, we selected three online forums containing the largest number of threads on PD. Threads focusing on the psycho-sexual impacts posted from January 1, 2011 to January 1, 2021 were compiled, and thematic analysis was performed on Dedoose. There were 277 unique posters, including 225 patients and 52 partners. Eighty-four categories and five themes were developed including information and social support, physical symptoms, psycho-sexual symptoms, treatment and effect, and impacts on partners and relationship. Emotional distress including depressed mood (n = 75, 33.3%) and feelings of isolation (n = 41, 18.2%) was prevalent. Partners developed sexual dysfunction including sexual dissatisfaction (n = 11, 21.2%) and dyspareunia (n = 4, 7.7%). Relationships experienced disruption (n = 14, 5.1%) or termination (n = 10, 3.6%). Posters received psychological treatment including psychotherapy (n = 20, 8.9%) and antidepressants (n = 17, 7.6%). Of these, 12 reported improvement and 11 stated no improvement. On these forums, psychological burden affecting individuals with PD and their partners is reported. Few seek help from a psychologist or therapist, and psychological distress may persist even after successful PD treatment. Further research is needed to identify strategies for effective psychological management.

Incidence of circumcision among insured adults in the United States.

PURPOSE: Although 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. METHODS: Using 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. RESULTS: We 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. CONCLUSION: This 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.

Posterior urethral stenosis: a comparative review of the guidelines.

PURPOSE: We 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). METHODS: The 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. RESULTS: The 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. CONCLUSION: The 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.

Implementation and value of a student-run volunteer clinical research program at an academic medical center.

Clinical research output in the emergency department (ED) continues to be constrained by limitations in funding for researchers, demands of patient care on ED providers, and difficulties in obtaining high-quality data. In response, several institutions have established programs in which student volunteers are integrated into department workflows to increase clinical research output and introduce pre-health students to careers in medicine. One such program, the student volunteer clinical research program, presently consists of over 40 undergraduate and post-baccalaureate student volunteers who screen, consent, and enroll patients into prospective studies in the ED of the University of California, Los Angeles (UCLA) Ronald Reagan Medical Center. The program is led by student coordinators who collaborate with departmental research staff and faculty. Our program is unique in that it is primarily run by the students themselves. Experienced student research associates facilitate recruitment through a competitive biannual application process, train new volunteers to perform on-shift research duties, and monitor participants for compliance with both hospital and program policies. Participation in the program provides students with exposure to frontline medical research, opportunities to observe clinical medicine, and access to a variety of program-specific resources including student-led committees, career development resources, and mentorship from peers, alumni, and faculty. This concept piece serves as a structural model for other institutions seeking to implement volunteer clinical research or bolster existing programs through increased student-led initiatives.

Incidence of venous thromboembolism in benign urologic reconstructive cases.

PURPOSE: To 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. METHODS: We 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. RESULTS: We 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. CONCLUSION: The 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.
