ABSTRACT
PURPOSE: To summarize the current state of knowledge on bladder cancer diagnosis and screening in neurogenic bladder patients, and to explore the potential contribution of biomarkers in this context. METHODS: A scoping review was performed to retrieve cystoscopy and urinary cytology performance for bladder cancer detection in neurogenic bladder patients. We also retrieved information of certified urinary biomarkers in bladder cancer detection and their potential application for this specific population. RESULTS: A total of 1092 articles were identified; 19 of them were included in the scoping review regarding cytology and cystoscopy performance in patients with neurogenic bladder and 33 were included as related to biomarkers in bladder cancer. No significant study stood out to recommend bladder cancer screening in this specific population using cytology and cystoscopy because of the scarcity of results, low level-of-evidence studies, and lack of studies specifically designed to assess the test performance in this population. Two biomarkers were retained as potential future diagnostic tools: FISH analysis to detect chromosomal changes, and PCR for TERT and FGFR3 promoter mutation detection, associated or not with KRAS mutation detection. CONCLUSION: There is no sufficient quality data to support cystoscopy and urinary cytology as effective tools for the diagnostic and surveillance of bladder cancer in neurogenic bladder patients. FISH analysis to detect chromosomal changes, and PCR for TERT and FGFR3 promoter mutation detection, associated or not with KRAS mutation detection, stand out as candidates of interest for bladder cancer detection in this specific population and should be prospectively tested.

BACKGROUND: Transperineal repair of rectourethral fistula (RUF) following prostate cancer treatment with gracilis muscle flap interposition (GMFI) leads to favourable outcomes, but published data are still lacking, notably concerning functional aspects. OBJECTIVE: To assess surgical and functional outcomes of this treatment of RUF. DESIGN, SETTING, AND PARTICIPANTS: A retrospective study was conducted in two referral hospitals including 21 patients who underwent RUF transperineal repair with GMFI between 2008 and 2020. SURGICAL PROCEDURE: The standard vertical perineal approach is performed for fistula dissection. Bladder and rectal defects are closed separately. After dissection from its facia, the flap is harvested, preserving its pedicle; it is brought to the perineum and placed between the urethra and the rectum to fully cover the sutures. MEASUREMENTS: Fistula closure (clinical data and postoperative cystography), digestive stoma closure, and complications graded according to the Clavien-Dindo classification were reviewed. Functional results were assessed using the Urinary Symptom Profile (USP) questionnaire, anal incontinence St Mark's score, Patient Observer Scar Assessment Scale (POSAS) score, and a nonvalidated Likert scale questionnaire assessing issues with lower extremity functionality. RESULTS AND LIMITATIONS: The median (interquartile range) follow-up was 27 (8-47) mo. Fistula closure was successful for 20 patients (95% success). Digestive stoma was closed in 10/12 shunted patients (83%). Two (9%) Clavien-Dindo grade ≥3b complications were reported (one urinoma in a kidney transplant patient and one thigh haematoma evacuation). Eighteen patients (86%) completed the postoperative questionnaire; 11/18 (61%) had significant urinary incontinence. The mean (standard deviation) USP dysuria score was 1/9 (1.2), mean St Mark's score was 5/24 (5), mean POSAS score was 19/70 (11), mean lower extremity functionality score was 2/20 (4), and mean procedure patient satisfaction score was 9/10 (2). The retrospective design and limited number of patients are the main limitations. CONCLUSIONS: The present study found an excellent success rate and low morbidity for RUF transperineal repair with GMFI. Functional outcomes were satisfactory despite a high urinary incontinence rate. PATIENT SUMMARY: We performed an analysis of the outcomes of perineal approach surgery with muscle interposition for closing abnormal communication between the bladder and the rectum after prostate cancer treatment. This surgical technique was found to be safe to perform and provides a high success rate, with patients being satisfied despite poor urinary continence outcomes.

Laubry-Pezzi syndrome is a rare congenital heart disease (CHD) combining a ventricular septal defect (VSD) and an aortic regurgitation (AR) due to a prolapse of the right coronary or, less frequently, non-coronary cusp. In the literature there are very few reports of long-term complications after surgical correction of this syndrome. We present the late occurrence of an aortic root pseudoaneurysm and a residual VSD in a patient with Laubry-Pezzi syndrome operated during childhood.
