BACKGROUND: To describe the surgical technique of robotic-assisted appendiceal onlay flap ureteroplasty combined with ureteral reimplantation to repair unilateral multifocal ureteral strictures in one stage and report 9-month follow-up outcomes.
METHOD: A longitudinal ventral incision of proximal ureter strictures No. 1 and 2 was performed, and the appendix was detubularised along its antimesenteric border. Then, the appendiceal onlay flap was anastomosed with the spatulated ureter in an onlay fashion. To manage the distal ureteral stricture No. 3, ureteral reimplantation was performed in a tension-free manner.
RESULTS: Voiding cystourethrography and antegrade urography showed urine regurgitation into the ureter without dilation and no obstruction of the reconstructed ureteral segment 7 weeks after surgery. No postoperative complications occurred during the 9-month follow-up.
CONCLUSIONS: Robotic-assisted appendiceal onlay flap ureteroplasty combined with ureteral reimplantation appears to be a safe and effective surgical method for repairing the unilateral multifocal ureteral strictures.
