Objective: To compile and evaluate the heritability and inheritance patterns of lower urinary tract symptoms (LUTS) in adult cohorts.

Methods: Searches of five databases (PubMed, Embase, APA PsycInfo, Global Health, and OVID Medline) commenced on 6 July 2024, resulting in 736 articles retrieved after deduplication. Studies evaluating heritability patterns, gene frequencies, and familial aggregation of symptoms were included for review. Screening and predefined eligibility criteria produced 34 studies for final review. A descriptive analysis of synthesised data was performed, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Cochrane Risk of Bias in Non-Randomised Studies of Interventions (ROBINS-I) tool and the Johanna Briggs Institute checklist were used to evaluate these studies.

Results: Ten of the 34 studies (29%) described general LUTS, 14 (41%) described symptoms due to benign prostatic enlargement (BPE), nine (26%) described urinary incontinence (UI; urge UI [UUI], stress UI [SUI] and mixed UI [MUI]), four (12%) described nocturia alone, two (6%) described overactive bladder (OAB), and four (13%) described other specific symptoms (frequency, postvoid residual urine volume). BPE symptoms, UI (MUI and UUI), nocturia alone, and frequency alone were associated with genetic predisposition, whilst OAB and SUI had more modest inheritance.

Conclusion: The pathogenetic and pharmacological mechanisms fundamental to LUTS manifestation are highly heterogeneous. Further work is required to evaluate the inheritance patterns of LUTS more extensively.

Objective: To evaluate the effectiveness and safety of salvage stereotactic ablative body radiotherapy (SABR) for recurrent renal cell carcinoma (RCC) after thermal ablation (TA).

Materials and methods: This study was a multi-institutional retrospective analysis of patients with recurrent RCC following TA who received SABR between 2016 and 2020. The primary study outcome was freedom from local failure, evaluated radiographically based on Response Evaluation Criteria in Solid Tumours (RECIST) v1.1. Distant failure, cancer-specific survival (CSS), overall survival (OS), treatment-related toxicity and renal function changes following SABR were the secondary outcomes. The Kaplan-Meier method was used to estimate freedom from local and distant failure, CSS and OS.

Results: Seventeen patients with 18 biopsy-confirmed RCCs were included, with a median (interquartile range [IQR]) age at time of SABR of 75.2 (72.6-68.7) years, a median (IQR) tumour size of 3.5 (1.9-4.1) cm and follow-up (reverse Kaplan-Meier method) of 3.36 (95% confidence interval [CI] 1.6-4.1) years. Six of the 17 patients had a solitary kidney. Five patients had failed repeat TA prior to SABR. The median (IQR) time from TA procedure to SABR was 3.03 (1.5-5.1) years. No patient experienced local progression, with a local control rate of 100%. Four patients, two with baseline metastatic disease, experienced distant progression. The distant progression-free survival, CSS and OS at 3 years were 72.1% (95% CI 51.9%-100%), 92.3% (95% CI 78.9%-100%) and 82.1% (95% CI 62.1%-100%), respectively. The median (IQR) glomerular filtration rate before SABR was 58 (40-71) mL/min, and at last follow-up, it was 48 (33-57) mL/min. No patient experienced grade 3+ toxicity or went on to develop end-stage renal disease.

Conclusion: The results showed that SABR appears to be an effective and safe salvage strategy in patients with recurrent RCC following TA.

Objectives: To report the clinical outcomes of the Victo™ (Promedon, Cordoba, Argentina) adjustable artificial urinary sphincter (AUS) implantation in a cohort of patients with severe urinary incontinence (UI) after prostate surgery.

Patients and methods: This study enrolled patients with UI following prostate surgery who underwent a Victo implantation between May 2018 and December 2023. Patients were prospectively evaluated at baseline, and at 3 and 12 months after device activation, and thereafter annually. The 24-h pad-weight test (24hPWT) was used to assess severity of UI, while the Patient Global Impression of Improvement (PGI-I) and patient satisfaction according to a Likert scale were used to measure patient-reported outcomes.

Results: A total of 96 patients with a median (interquartile range [IQR]) age of 68 (65-72) years were included in the final analysis. The median (IQR) follow-up was 3 (1-4) years. In all, 10 patients completed the 5-year follow-up. After the treatment, we observed a significant reduction in 24hPWT by the median of 83% (P < 0.001) at 3 months and by a median of 79% (P < 0.001) at 3 years. According to the PGI-I, a total of 87%, 92%, 87%, 81%, 83%, and 50% (five of 10) of patients rated their condition/incontinence as 'very much improved', 'much improved' or 'little improved' at 3 months, 1-, 2-, 3-, 4-, and 5-year follow-up visits, respectively. The proportion of patients, who were 'very satisfied' or 'satisfied' with the treatment outcome was 79%, 80%, 75%, 69%, 80%, and 60% (six of 10) at 3 months, 1-, 2-, 3-, 4-, and 5-years, respectively. There were a total of 13 (14%) device failures during the follow-up period.

Conclusion: In conclusion, our data suggest that Victo AUS significantly reduces the severity of UI after prostate surgery and provides a reasonably high patient-reported satisfaction with treatment outcomes at mid-term follow-up.

Objective: To quantify the oncological risks of bladder-sparing therapy (BST) in patients with Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC) compared to upfront radical cystectomy (RC).

Patients and methods: Pre-specified data elements were collected from retrospective cohorts of patients with BCG-unresponsive NMIBC from 10 international sites. After Institutional Review Board approval, patients were included if they had BCG-unresponsive NMIBC meeting United States Food and Drug Administration criteria. Oncological outcomes were collected following upfront RC or BST. BST regimens included re-resection or surveillance only, repeat BCG, intravesical chemotherapy, systemic immunotherapy, and clinical trials.

Results: Among 578 patients, 28% underwent upfront RC and 72% received BST. The median (interquartile range) follow-up was 50 (20-69) months. There were no statistically significant differences in metastasis-free survival, cancer-specific survival, or overall survival between treatment groups. In the BST group, high-grade recurrence rates were 37% and 52% at 12 and 24 months and progression to MIBC was observed in 7% and 13% at 12 and 24 months, respectively. RC was performed in 31.7% in the BST group and nodal disease was found in 13% compared with 4% in upfront RC (P = 0.030).

Conclusion: In a selected cohort of patients, initial BST offers comparable survival outcomes to upfront RC in the intermediate term. Rates of recurrence and progression increase over time especially in patients treated with additional lines of BST.
