abstract
OBJECTIVE: To determine surgical outcomes in a large of cohort men undergoing robotic-assisted posterior urethroplasty (RPU), which has been described in small series as a viable option. MATERIALS AND METHODS: We performed a retrospective review of all 105 men who underwent RPU from October 2014 to August 2022 at a single institution. We evaluated postoperative outcomes, including complications; surgical success defined as no need for reintervention; and incontinence requiring artificial urinary sphincter placement. We performed descriptive statistics and Chi-square testing to determine if outcomes were associated with certain posterior urethral disease etiologies. RESULTS: Mean follow-up time was 18.7 months. Over half of patients (57.1%) received prior pelvic radiation. The most common reconstructive techniques were excision and primary anastomosis (n=45, 30.0%), re-sitting of the bladder neck (n=26, 24.8%), Y-V plasty (n=21, 20.0%), and buccal mucosal graft urethroplasty (n=14, 13.3%). Forty-one patients (39.0%) required a combined abdomino-perineal approach. Seven patients (6.7%) had ≥ CD grade 3 complications within 30 days. Thirty patients (28.6%) developed incontinence with subsequent AUS placement. One-quarter (24.8%) of patients required at least one subsequent surgical reintervention. CONCLUSIONS: In the largest RPU cohort to date, surgical success rates were similar and continence rates were improved compared to open surgery and align with existing robotic series, adding to the growing body of evidence demonstrating advantages of RPU.
