[Compare the outcome of ureteroscopic lithotripsy with ureteroscopic management after failed extracorporeal shock wave lithotripsy for ureteral calculi].

OBJECTIVE: To compare the efficacy and complication of ureteroscopic lithotripsy and ureteroscopic management for ureteral calculi after failed extracorporeal shock wave lithotripsy (ESWL). METHODS: One hundred and thirty-six cases with ureteral calculi after failed ESWL and 189 cases with ureteral calculi were treated with ureteroscopic lithotripsy (URSL). Clinical data of two groups were analyzed retrospectively. RESULTS: The mean operating time and therapeutic time in ESWL-URSL group was longer than that in URSL group, while the rate of polypi hyperplasia and open-surgery in ESWL-URSL group was 34.6%, 5.88% versus 28.3%, 1.59% in URSL group. There is no significant statistical difference in stone-free rate between two groups. CONCLUSION: Ureteroscopic management can be preferred for the patients with disadvantage of ESWL in some condition.
