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.
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.
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.
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.
描述机器人辅助阑尾补片输尿管成形术联合输尿管再植术一期修复单侧多灶性输尿管狭窄的手术技术，并报告9个月的随访结果。
在近端输尿管第1和第2处狭窄处做纵向腹侧切口，沿阑尾系膜对侧缘将阑尾去管化。然后，将阑尾补片以补片方式与切开的输尿管吻合。为处理远端输尿管第3处狭窄，以无张力方式行输尿管再植术。
术后7周膀胱尿道造影和顺行尿路造影显示无尿液反流至输尿管且无扩张，重建的输尿管段无梗阻。9个月随访期间未发生术后并发症。
机器人辅助阑尾补片输尿管成形术联合输尿管再植术似乎是修复单侧多灶性输尿管狭窄的一种安全有效的手术方法。
