    Abstract:
    OBJECTIVE: To prospectively review our experience with extravesical robotic-assisted laparoscopic ureteral reimplantation to determine whether postoperative voiding dysfunction can be avoided with pelvic plexus visualization and to assess the efficacy of this approach for the treatment of vesicoureteral reflux (VUR). METHODS: We prospectively followed 150 patients who underwent bilateral extravesical robotic-assisted laparoscopic ureteral reimplantation by a single surgeon at an academic institution. Each patient was followed for a 2-year period. All 150 patients had primary VUR of grade 3 or greater bilaterally, with 127 having parenchymal defects found on renal scans. All patients were toilet trained before surgical intervention. The operation was performed with an extravesical transperitoneal approach with robotic assistance using the daVinci Surgical System. All patients underwent voiding cystourethrography at 3 months postoperatively to document the resolution of VUR. Voiding dysfunction was assessed in each patient by uroflow, postvoid residual urine volume, and a validated questionnaire. RESULTS: The operative success rate was 99.3% for VUR resolution on voiding cystourethrography. One patient with bilateral grade 5 VUR that was downgraded to unilateral grade 2 VUR was considered to have treatment failure. This patient ultimately underwent subsequent subureteral injection therapy after an episode of pyelonephritis. No patient experienced de novo voiding dysfunction. CONCLUSION: Bilateral nerve-sparing robotic-assisted extravesical reimplantation has the same success rate as the traditional open approaches, with minimal morbidity and no voiding complications in our series.
