Abstract
Objective To assess the efficacy and safety of Ho: YAG laser lithotripsy during retrograde ureterscopic management of ureteral calculi after extracorporeal shock wave lithotripsy (ESWL) failed. Methods A total of 92 patients who failed ESWL from January 2013 to March 2015 were treated by ureteroscpic Ho: YAG laser lithotripsy. Results The ureteroscopic Ho: YAG laser lithotripsy success rate was 92.39%(85/92), four cases of ureteroscopy placement failed and three cases of calculi translocation. Among the 92 cases, there were 66 cases of polypi and granulation, 15 cases of distal ureteral stricture, seven cases of embed ureteral calculi and four cases of ureteral distortion. Conclusions Ureteroscopic Ho: YAG laser lithotripsy after ESWL failed is an effective treatment modality for ureteral calculus, with high fragmentation rates and minimal tissue damage. Key words: Ureteral calculi; Extracorpreal shock wave lithotripsy; Ureteroscopy; Holmium laser lithotripsy
