Abstract：Objective:To evaluate the feasibility, efficacy and safety of the retroperitoneal laparoscopic pyeloplasty combined with flexible cystoscope in the treatment of ureteropelvic junction obstruction with coexistent stone disease.Methods:We reviewed data on 5 patients undergoing laparoscopic pyeloplasty through retroperitoneal approach and pyelolithotomy with flexible cystoscope between January 2012 and March 2013. The clinic parameter involves operational time, blood loss, postoperative hospital stay, the status of stone-free, perioperative complications, conversion to open procedure, the follow-up of radiology.Results:No procedure converted to open surgery. The mean operational time is 126 mins(ranged from 90 to 170 mins). One patient had one residual calculi encrusted in a calyx with obstructive neck indicated by the postoperative radiological image. The blood loss ranged from 10 to 30 mins. The urinary leak happened in one patient who got recovered after 6 days conservative treatment. The mean postoperative hospitality is 8 days (ranged 6-12 days). The mean period of follow-up is 6 months (ranged 1-9 months).Conclusions:The retroperitoneal laparoscopic pyeloplasty combined with flexible cystoscope is a feasible, efficient and safe minimally invasive technique in the treatment of ureteropelvic junction obstruction with coexistent stone disease.
