Bladder cancer (BC) remains the most common malignancy of urinary tract. Sex-related differences in BC epidemiology, diagnosis, therapy, and outcomes have been reported. Throughout the recent years, extensive research has been devoted to genetic and molecular alterations in BC. Apart from the molecular background, another related concept which has been speculated to contribute to gender diversities in BC is the role of urinary pathogens in bladder carcinogenesis. Microbiome studies, fueled by the availability of high-throughput DNA-based techniques, have shown that perturbation in the microbiome is associated with various human diseases. The aim of this review is to comprehensively analyze the current literature according to sex-related differences in the microbiome composition in BC.

In the era of antibiotic overuse and increasing antibiotic resistance, there is a gap in evidence regarding antibiotic stewardship, and in particular, perioperative antibiotic prophylaxis after urethral reconstruction. The aim of this systematic review was to evaluate the effectiveness and relevance of postoperative antibiotic prophylaxis after male pediatric and adult urethral reconstruction. An online search of MEDLINE database via PubMed was performed. The systematic review was registered in PROSPERO (CRD42022348555) and was conducted according to the PRISMA guidelines and AMSTAR 2 checklist. A narrative synthesis of included studies was performed. After the screening of 1176 publications, six studies regarding antibiotic prophylaxis after hypospadias reconstruction and two studies regarding antibiotic prophylaxis after urethroplasty in adults were eligible to be included in the systematic review. All but one of the studies on hypospadias repair showed no benefit from postoperative antibiotic prophylaxis. The level of evidence on postoperative antibiotic prophylaxis after urethroplasty in adults is low. Neither of the two studies included in the review showed a benefit from antibiotic use. Postoperative prophylaxis after hypospadias repair is not effective in preventing urinary tract infections and wound infections. It seems that the use of postoperative prophylaxis after urethroplasty in adults is also not beneficial, but there is a high need for high-quality scientific data.

In some patients submitted to transurethral resection of the prostatic (TURP) or prostatectomy (OAE) due to benign prostate hyperplasia (BPH), pathological evaluations (PE) revealed coexistence of prostate cancer (PCa) and BPH. The aim of the study is to evaluate the incidence of PCa diagnosed incidentally in prostate specimens taken during BPH surgery, to assess the need of routine PE and to define the group of patients in whom PE could be abandoned without the risk of omitting clinically significant PCa. 968 consecutive men were subjected to surgical treatment due to BPH in Jan. 2004-Sep. 2010. 823 (85%) underwent TURP and 145 (15%) OAE. Incidental (Inc) PCa was diagnosed in 34(3.5%) pts. T1a and T1b stages were determined in 19 (2%) and 15 (1.5%) cases. Preoperative prostate biopsy due to abnormal prostate specific antigen (PSA) or digital rectal exam (DRE) was performed in 85 (8.8%) pts. Of PCa pts, 7 (20.58%) had undergone a cancer negative biopsy preoperatively. In BPH pts, 78 (8.35%) had undergone a prostate biopsy previously (p 6 only in 4 cases. Despite the fact of low PCa detection rate observed in our study, this condition was clinically relevant in 15 (1.5%) subjects. It is difficult to establish any cut off values of pts' age, Pv, serum PSA level suggestive of negligible risk for prostate cancer.

Sex-specific differences in outcomes of patients diagnosed with high-risk non-muscle-invasive bladder cancer (HR-NMIBC) have been reported with controversial findings. This study aims to investigate sex-specific diversities in the treatment and oncologic outcomes of primary HR-NMIBC in a multicenter setting. A multicenter retrospective analysis of 519 patients (388 men and 131 women) treated with transurethral resection (TUR) for primary HR-NMIBC was performed. Univariable and multivariable Cox regression models were used to investigate the association of clinico-pathologic features and generate hazard ratios (HRs). Second-look TUR (reTUR) was performed in 406 (78%) patients. A total of 218 (42%) of patients were subjected to an induction course of intravesical BCG (Bacillus Calmette–Guérin) plus maintenance therapy. The median follow-up was 44 months. Among the entire cohort, 238 (46%) and 86 patients (17%) had recurred and progressed to muscle-invasive disease (MIBC), respectively. Female sex was associated with increased risk of disease recurrence in the entire cohort: HR = 1.94, 95% CI = 1.48–2.55, p < 0.001 and HR = 1.91, 95% CI = 1.39–2.60, p < 0.001 in univariate and multivariate analysis, respectively. In patients subjected to reTUR and treated additionally with BCG, female sex was associated with increased risk of disease recurrence in univariate analysis (HR 1.81, 95% CI 1.07–3.06, p = 0.03), but not in multivariate analysis (HR 1.99, 95% CI 0.98–4.02, p = 0.06). There was no difference between sexes with regard to disease progression. HR-NMIBC diagnosed in females is associated with higher risk of disease recurrence when compared to males.

Background/Objectives: Urethral stricture disease, characterized by narrowing of the urethra due to scar tissue, affects urinary and sexual health. While urethroplasty is the standard treatment, its impact on erectile function is less understood. This study examines changes in International Index of Erectile Function (IIEF) scores post-urethroplasty across various stricture etiologies, identifies predictors of erectile function outcomes, and explores recovery trajectories following surgery. Methods: This multicenter retrospective study included 103 patients who underwent urethroplasty between 2017 and 2023. Preoperative and postoperative IIEF scores at 3 and 6 or 12 months were analyzed. Stricture etiologies included pelvic fracture urethral injury, transurethral resection, catheterization, idiopathic, and hypospadias. The Wilcoxon signed-rank test and multivariate regression models were used to assess changes in IIEF scores and identify significant predictors. Results: Preoperative erectile function and patient age were significant predictors of postoperative outcomes. Younger patients and those with higher baseline IIEF scores experienced better erectile function post-surgery. Long-term outcomes (6 to 12 months) were significantly worse for strictures involving both penile and bulbar regions. Multivariate analysis showed higher pre-surgery IIEF scores and younger age were associated with better outcomes both short-term (R2 = 0.562) and long-term (R2 = 0.507). Diabetes was associated with worse erectile function outcomes at 3 months post-surgery. Conclusions: Younger patients and those with higher baseline IIEF scores have better erectile function outcomes following urethroplasty. Complex strictures involving both penile and bulbar regions adversely affect long-term outcomes. Additionally, the presence of diabetes is correlated with diminished erectile function in the short-term postoperative period.
