Description
Summary:To describe the use of the robotic platform for proximal suture placement during perineal urethroplasty in the posterior and proximal anterior urethra. Repair of posterior urethral and proximal bulbar strictures requires deep perineal dissection, making visualization and accurate placement of sutures challenging. The robotic platform has demonstrated benefits in these characteristics in deep pelvic surgery. We report a retrospective review of 10 patients who underwent robotic-assisted urethroplasty at a single institution by a single surgeon in a 1 year period. All patients underwent a standard perineal dissection with robotic-assisted placement of proximal sutures. Postoperative outcomes include urethroplasty leak rate as determined by voiding cystourethrograms, urethroplasty success rate, and perioperative complications. The mean age of this cohort was 43 years old (14-68). Average stricture length was 2.2 cm (1.5-3.0 cm) and most frequently in the bulbar urethra (5/10). Seven patients underwent nontransecting urethroplasties while 3 underwent transecting anastomotic repair. At postoperative voiding cystourethrograms, no patient had urinary extravasation. Average set-up time for the robotic portion of the surgery was 15 minutes with 30-45 minutes needed for suture placement. Robotic-assisted urethroplasty provides excellent visualization and ergonomics for posterior and proximal bulbar urethral reconstruction. This is particularly helpful in patients with narrow pelvic anatomy and long distances from the perineal skin to the proximal urethral edge. Operative and postoperative outcomes are comparable to the standard approach with improved surgeon comfort and visualization. Additional follow-up is required to assess long-term outcomes in comparison to a standard approach.
