Abstract：Objective： To explore the feasibility and effectiveness of laparoscopic ureteroplasty with Boari flap. Methods： A retrospective analysis was performed on the clinical data and perioperative results of 11 patients with middle and lower ureteral stenosis treated by laparoscopic ureteroplasty with Boari flap from November 2017 to August 2019 in our department. The key surgical steps were summarized and all patients were followed up for at least 6 months to record hydronephrosis alleviation. Results： All operations of 11 cases were successfully done, and no one was converted to open surgery. The median operation time and intraoperative blood loss were 160 （145, 240） min and 60 （50, 85） mL, respectively. No urinary leakage occurred after operation, the pelvic drainage tube and catheter were removed 3-5 days and 2 weeks after operation respectively, and the median hospital stay was 8 （7, 10） days. The double J tubes were removed 3 months after operation, and during 6-18 months of post-operation follow-up, CT scanning showed that hydronephrosis degree was significantly reduced. Conclusion： Laparoscopic ureteral replacement by Boari flap is safe and feasible for the treatment of middle and lower ureteral stricture. It has the advantages of small trauma, satisfactory effect and fast recovery, so it is worth popularizing in units with mature laparoscopic technology.
