Beyond laboratory, imaging and endoscopic procedures, new diagnostic tools are increasingly being sought for the diagnosis of upper urinary tract urothelial carcinoma (UTUC), especially those that are non-invasive. In this systematic review, we aimed to determine the effectiveness of non-invasive tests in the diagnosis of UTUC. PubMed and Embase electronic databases were searched to identify studies assessing effectiveness of non-invasive tests in the primary diagnosis of UTUC. The study protocol was registered with PROSPERO (CRD42020216480). Among 10,084 screened publications, 25 were eligible and included in the analysis. Most of them were conducted on small samples of patients and the control groups were heterogenous. The test used in the largest number of studies was voided urinary cytology, which has poor sensitivity (11–71.1%) with favorable specificity (54–100%). Fluorescence in situ hybridization in diagnostic cytology showed higher sensitivity (35–85.7%) with equally good specificity (80–100%). There were also studies on the use of tests known to diagnose bladder cancer such as NMP22, uCYT or BTA test. Other urine or blood tests have been the subject of only isolated studies, with varying results. To conclude, currently there is a lack of high-quality data that could confirm good effectiveness of non-invasive tests used in the diagnosis of UTUC.

Indications for restaging transurethral resection of the bladder tumor (reTURBT) in patients with non-muscle-invasive bladder cancer (NMIBC) remain controversial. This study was aimed at evaluation of clinical value and safety of reTURBT in different clinical indications. This is a retrospective analysis of consecutive 141 patients who underwent TURBT followed by reTURBT in years 2011–2015 in a single department. Pathological results and surgical complications were analyzed in the whole study cohort and stratified by clinical stage (Ta, T1, Tx (no muscle in the specimen)) and grade (low-grade (LG), high-grade (HG)) of bladder cancer diagnosed at primary TURBT. Full data was available for 132 patients. Residual disease was found in 53 patients (40.2%) with highest rate for Ta-HG cases (57.1%) followed by T1-HG (51.4%), Tx-HG (45.2%), T1-LG (32.1%), and Tx-LG (25.8%). In the multivariate analysis, high grade (p = 0.02) was the only independent predictor of residual disease. Upstaging to muscle-invasive bladder cancer was noticed in 9 patients (6.8%). The rate of grade ≥ 2 Clavien-Dindo complications (1.5 vs. 5.3%) did not differ significantly between TURBT and reTURBT cases. ReTURBT is a safe procedure that remains crucial for therapeutic and staging purposes in patients with T1, Tx, or high-grade bladder cancer found in the primary resection.

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.

Objective: To analyze the frequency of performing bimanual palpation (BP) during transurethral resection of the bladder tumor (TURBT) and to identify its predictors. Material and methods: This retrospective analysis enrolled 568 consecutive patients, who underwent TURBT due to primary bladder cancer. There were thirty surgeons involved in the analysis, each performed a mean of 18.9 TURBTs (range 1-43). Univariate and multivariate logistic regression analyses were performed to identify factors predicting the BP use. Results: Two hundred and sixty-five patients (46.7%) underwent BP. BP was performed in 36.1% of Ta tumors, 49.1% of T1 tumors and 76.6% of ≥T2 tumors (p3 cm and in 33.3% of tumors

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.

Urethral complications following urethral lengthening in transgender men, such as strictures and fistulas, are common and frequently necessitate secondary surgical interventions. These surgeries vary significantly in their techniques and are evaluated with considerable heterogeneity, making a synthesized presentation of their outcomes valuable for guiding clinical management. This systematic review included 14 studies selected through a database search (Medline, Embase, Web of Science) that reported urethral complications after urethral lengthening. Among the 595 patients considered, 76% underwent phalloplasty and 24% underwent metoidioplasty. Our findings highlight that staged urethroplasty techniques demonstrated the lowest recurrence rates (0–25%), particularly in the management of long strictures in the pendulous urethra. In contrast, one-stage urethroplasties—especially those performed without augmentation—were associated with high recurrence rates, reaching approximately 50%, even when buccal mucosa grafts were used for augmentation. Patient-reported outcomes were documented in only one-third of the included studies, underscoring the limited functional evaluation of urethroplasty outcomes following phalloplasty. The considerable variability in urethroplasty techniques, types of genital reconstruction, and reporting standards highlights the need for more comprehensive and standardized outcome assessments. Future studies will be essential in advancing our understanding and optimizing the management of these complex cases.
