We aimed to study the safety and efficacy of the cystoscopy-assisted nonrefluxing ureteral reimplantation technique using submucosal tunneling during laparoscopic ureteroneocystostomy (UNC) with a psoas hitch in patients with distal ureter stricture after gynecologic surgery. We reviewed six female patients who underwent gynecological surgeries. All patients showed persistent postoperative distal ureter stricture or obstruction. These patients underwent laparoscopic nonrefluxing UNC with a psoas hitch using a submucosal tunneling technique combined with cystoscopy at our institute. They had corrective surgery at an average of 13.3 weeks after ureteral injury. The short-term success was confirmed either by voiding cystourethrography (VCU) or by diuretic isotope renal scan (MAG-3) conducted 3 months after the operation. None of the patients showed evidence of postoperative stricture at the reimplanted site and reflux on either MAG-3 renal scan or VCU. None of the patients showed major or minor complications during follow-up. It is safe and feasible to perform the laparoscopic nonrefluxing UNC with a psoas hitch using a submucosal tunneling technique combined with cystoscopy for ureteral stricture.
