Laparoscopic and Robot-Assisted Laparoscopic Management of Iatrogenic Ureteral Strictures: Preliminary Experience.

Iatrogenic ureteral strictures are uncommon but challenging to manage. We present our expertise in laparoscopic and robot-assisted laparoscopic ureteroureterostomy (LUU and RAUU) for lumbar and iliac strictures and laparoscopic ureteral reimplantation for pelvic strictures. A descriptive study was conducted on nine adult patients who underwent minimally invasive procedures. Six had lumbar or iliac ureteral strictures-five due to ureterorenoscopy and one following pancreaticoduodenectomy for pancreatic cancer. Three developed pelvic strictures after ureterorenoscopy. Preoperative evaluation included a medical history review, abdominal ultrasound, and CT scan. Success was characterized by the absence of symptoms and the lack of obstruction on follow-up imaging at one year. All procedures were technically feasible, with a median operating time of 105 min and a median hospital stay of four days. No major complications occurred. One patient experienced ureteral stricture recurrence following a laparoscopic approach for a lumbar stricture, and required a permanent double-J stent. At a median follow-up of 38 months, 88.88% of patients remained asymptomatic with preserved renal function. Our findings suggest that robotic and laparoscopic ureteral reconstruction performed by experienced surgeons at a tertiary center is a safe and effective option with a low complication rate.
