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

OBJECTIVE: 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 and 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 1508 (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 were 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 2 or more GU organs injured. Seventy-three of those with kidney injuries (11.2%) underwent nephrectomy. Only 1 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 3 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. Ninety-four percentage of fatal cases had a concomitant non-GU injury. CONCLUSION: GU injuries account for 2.6% of all SII. These patients are often young white males with known mental or personality disorders. Kidneys were the most common injured and mortality was highest in cases of kidney and bladder injuries with multi-organ trauma involving non-GU organs.

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.

Consumer product-related female genital injuries in the USA from 2013 to 2022.

BACKGROUND: Consumer product-related genital injuries in females across all age groups are understudied. Existing research focuses primarily on paediatric populations. We aimed to determine characteristics, trends and predictors of hospitalisation. METHODS: The National Electronic Injury Surveillance System database was queried for female genital injuries from 2013 to 2022. We stratified our population into four age groups (<18, 18-34, 35-54, >54 years). Automated text matching and manual reviews were employed for variable extraction. χ2 tests and logistic regression were conducted, accounting for survey design and weights. RESULTS: 9054 cases representing a national estimate of 252 329 injuries (95% CI 188 059 to 316 599) were identified. Paediatric injuries were most common (61%) and seniors had the highest hospitalisation rates (28%). Falls were common in paediatric (51%) and senior (48%) groups, whereas self-induced and topical application injuries were more frequent among adults aged 18-34 and 35-54. Injuries predominantly involved playground equipment and bicycles in children, razors and massage devices in adults aged 18-34 and 35-54 and household structures in seniors. Hospitalisation increased over the decade from 7% to 9%; significant predictors of hospitalisation were Asian race (OR=3.39, 95% CI 1.83 to 6.30), fractures (OR=7.98, 95% CI 4.85 to 13.1) and urethral injury (OR=3.15, 95% CI 1.30 to 7.63). CONCLUSIONS: Our study identifies distinct patterns in female genital injuries across ages. In the paediatric cohort, injuries are often linked to playgrounds and bicycles. For adults, grooming products are frequently implicated. Seniors commonly suffer injuries from household structures such as bathtubs. These patterns may inform discussions on tailored preventive strategies.

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.

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.

Oral phosphodiesterase type 5 inhibitors and priapism: A VigiBase analysis.

PURPOSE: To explore the differences of priapism events among a diverse cohort taking erectogenic medicines (i.e., phosphodiesterase type 5 inhibitors [PDE5i] and intracavernousal drugs). METHODS: We 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. RESULTS: From 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). CONCLUSIONS: PDE5i use shows disproportionate priapism signals which are higher in young patients.

Conservative Management of Penile and Urethral Lichen Sclerosus: A Systematic Review.

PURPOSE: We evaluate the efficacy and safety profiles of currently available conservative management options for penile and urethral lichen sclerosus. MATERIALS AND METHODS: A 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. RESULTS: Seventeen 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. CONCLUSIONS: Topical 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.

Urethral Slings for Irradiated Patients With Male Stress Urinary Incontinence: A Meta-analysis.

OBJECTIVE: To systematically compare success, cure and complication rates of urethral sling surgeries in stress urinary incontinence patients with and without a history of pelvic radiotherapy (RT). MATERIALS AND METHODS: We searched PUBMED, EMBASE, and Web of Science to identify relevant articles. The primary outcomes were the success and cure rates. The secondary outcomes included the rates of infection, urethral erosion, total complications, explantation, and satisfaction. Outcomes were analyzed using a random-effects model to calculate the unadjusted odds ratio (OR) in patients with a history of RT compared with those without prior RT. RESULTS: On pooled analysis, we found significantly lower odds of success (OR 0.68; 95% confidence interval [CI] 0.53-0.87, P < .001) and cure (OR 0.67; 95% CI 0.55-0.82, P < .001) in radiated patients than in nonirradiated patients. Subgroup analysis by type of sling showed significantly lower odds of success in Advance subgroup (OR 0.66; 95% CI 0.45-0.95, P < .001) and significantly lower odds of cure in Advance (OR 0.59; 95% CI 0.36-0.95, P < .001) and Atoms subgroups (OR 0.70; 95% CI 0.54-0.93, P < .001). We also found significantly greater odds of sling explantation (OR 2.93; 95% CI 1.62-5.29, P < .001) and infection (OR 3.06, 95% CI 1.03-9.07, P < .001) in radiated patients than in nonradiated patients. CONCLUSION: Patients with a history of pelvic RT have lower odds of success and cure and higher odds of infection and sling explantation than those without a history of pelvic RT.

Grade V renal trauma management: results from the multi-institutional genito-urinary trauma study.

PURPOSE: To investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management. METHODS: We 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). RESULTS: Eighty 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. CONCLUSION: Successful 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.

The Impact of Patient Travel Distance on Outpatient Visit Satisfaction: Comparison of Telehealth and Traditional In-Person Visits.

Introduction: Patient satisfaction has been shown to changes based on the distance a patient to see their physician. We sought to examine the effects of telehealth on patient satisfaction. Methods: We examined patient satisfaction survey scores from outpatient clinics at University of California, San Francisco. Patient home and clinic addresses were used to calculate distance in kilometers (km). Outcomes were "top scores (9-10)" and "low scores (<9)." Results: Of 103,124 evaluations that met inclusion criteria, those where patient traveled >100 km for in-person visits had more top scores (84%) than those traveled <10 km (80.2%). Relative to in-person visits, telehealth was associated with an increased odds (odds ratio [OR]: 1.48) of receiving a top score at all distances. Those traveling >100 km had the highest odds of top score for telehealth (OR: 1.86). Conclusions: Patients receiving care through telehealth, particularly those far from the outpatient clinic, are more likely to provide high patient satisfaction scores for the visit provider.

Adverse reactions of PDE5 inhibitors: An analysis of the World Health Organization pharmacovigilance database.

BACKGROUND: Despite their efficacy and general safety, rare but devastating adverse drug reactions have been associated with phosphodiesterase type 5 inhibitors. OBJECTIVES: To determine the safety profile of oral phosphodiesterase type 5 inhibitors with a particular focus on priapism and malignant melanoma. MATERIALS AND METHODS: In 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. RESULTS: A 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. CONCLUSION: Phosphodiesterase 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.

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.

Alpha-Lipoic Acid Supplementation for Male Partner of Couples with Recurrent Pregnancy Loss: A Post hoc analysis in Clinical Trial.

BACKGROUND: Increased sperm DNA damage is known as one of the causes of recurrent pregnancy loss (RPL) which can be due to increased levels of oxidative stress. Therefore, the aim of this study was to assess the effect of alpha-lipoic acid (ALA) on sperm parameters and sperm functions in couples with a history of RPL. MATERIALS AND METHODS: In this post hoc analysis in clinical trial study, a total of 37 couples with RPL (n=12 and n=25 for placebo and ALA groups, respectively) were considered. Men were treated with ALA (600 mg/day) or placebo for 80 days. Semen samples were acquired from the participants before initiation and after completion of the medication course and assessed regarding conventional sperm parameters, chromatin damage/integrity, intracellular oxidative stress, lipid peroxidation, and seminal antioxidant characteristics. Individuals were further followed up for twelve months for pregnancy occurrence and outcomes. Finally, after excluding patients with no history of RPL, the data was analyzed. RESULTS: No significant differences were observed between the baseline measures of the aforementioned parameters except for seminal volume. After the intervention, the mean sperm DNA damage, protamine deficiency, and persisted histones were significantly lower in the ALA group than in placebo receivers (P<0.05). A decrease in the mean of seminal total antioxidant capacity (P=0.03), malondialdehyde (P=0.02), and sperm DNA damage (P=0.004) as well as an increase in sperm total motility (P=0.04) after treatment with ALA was noticed. In addition, the mean of protamine deficiency and persisted histones were declined post-ALA therapy (P=0.003 and 0.002, respectively). The percentage of spontaneous pregnancy in the ALA group (4 of 25 cases; 16%) was higher than in the placebo group (1 of 12, 8.3%). CONCLUSION: ALA-therapy attenuates sperm DNA damage and lipid peroxidation while enhancing sperm total motility and chromatin compaction in the male partner of couples with PRL (registration number: IRCT20190406043177N1).

Role for Conservative Management in Grade V Renal Trauma.

PURPOSE: We 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 METHODS: We 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. RESULTS: Of 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. CONCLUSIONS: A 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.

Alpha-Lipoic Acid Ameliorates Sperm DNA Damage and Chromatin Integrity in Men with High DNA Damage: A Triple Blind Randomized Clinical Trial.

OBJECTIVE: Evidence suggests the contributory role of oxidative stress (OS) to sperm DNA damage and eventually, male infertility. Antioxidant supplementation has exhibited favorable results regarding seminal OS, sperm DNA damage, and chromatin integrity. We aimed to evaluate the effect of alpha-lipoic acid (ALA) supplementation on semen analysis, sperm DNA damage, chromatin integrity, and seminal/intracellular OS in infertile men with high sperm DNA damage. MATERIALS AND METHODS: In this randomized triple-blind placebo-controlled clinical trial study, we opted for a triple-blind controlled clinical trial design. Considering the study's inclusion criteria for the level of sperm DNA fragmentation (higher than the threshold of 30 and 15%), 70% of participants were selected for this clinical research study. Subjects were divided into case and control groups receiving oral ALA (600 mg/day) and placebo for eighty days, respectively. Sperm parameters and functional tests were examined and compared before and after treatment. The final sample size was 34 and 29 for ALA and placebo receivers, respectively. RESULTS: No significant differences were observed about anthropometrics and baseline measures of semen analysis, DNA damage, OS, and chromatin integrity between the two groups. Conventional semen parameters were enhanced insignificantly in both groups (P>0.05). DNA damage decreased significantly in the ALA group, as per sperm chromatin structure assay (SCSA, P<0.001). Moreover, chromomycin A3 (CMA3) staining results indicated a decrease in nuclear protamine deficiency post-ALA therapy (P=0.004). Lipid peroxidation decreased significantly after treatment with ALA (P=0.003). Further, seminal antioxidant capacity/activity did not differ significantly in either of the groups (registration number: IRCT20190406043177N1). CONCLUSION: An 80-day course of oral ALA supplementation (600 mg/day) alleviates sperm OS, DNA damage, and chromatin integrity in men with high sperm DNA damage.

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.

Alcohol Intoxication Is Associated With Bladder Injury and Bladder Surgical Repair in Patients Sustaining Motor Vehicle Collisions.

PURPOSE: Alcohol 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 METHODS: We 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. RESULTS: We 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. CONCLUSIONS: Alcohol 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.
