Abstract Objective To compare the application effects of flexible ureteroscopic lithothripsy（FURL）and Shuotong ureteroscopic lithotripsy（STL）on patients with failure of extracorporeal shock wave lithotripsy（ESWL）treatment of upper ureteral calculi. Methods A retrospective analysis was performed on 76 patients with upper ureteral calculi who failed ESWL treatment.According to different treatment methods,the patients were divided into group A（STL,40 cases）and group B（FURL,36 cases）.The intraoperative surgical time and postoperative hospital stay,postoperative infection rate,stone clearance rate at 1 d and 1 month after surgery and clearance rates of stones with diameters larger than or less than 2 cm at 1 d and 1 month after surgery were compared between the two groups,and the causes were analyzed. Results The surgical time of group B was significantly shorter than that of group A（P<0.05）.The postoperative hospital stay of group B was slightly shorter than that of group A（P>0.05）.There was no significant difference in the total clearance rate at 1 month after surgery（P>0.05）,but the stone clearance rate in group A was significantly better than that in group B at 1 d after surgery（P<0.05）.The clearance rate of stones with diameter larger than 2cm in group A was significantly better than that in group B（P<0.05）,but there was no significant difference in the total clearance rate of stones with diameter less than 2cm（P>0.05）. Conclusion Both FURL and STL are significantly effective in treating upper ureteral calculi with failure of ESWL treatment.STL is better than FURL in treating stones with diameter larger than 2 cm.
