Evaluation of efficacy between emergency ureteroscopy lithotripsy and extracorporeal shock wave lithotripsy in management of middle or lower ureteral calculi with acute renal colic

Objectives To compare the efficacy and complication of emergency ureteroscopy lithotripsy(URSL) and extracorporeal shock wave lithotripsy(ESWL) in management of middle or lower ureteral calculi with a-cute renal colic.Methods 45 cases with middle or lower ureteral calculi were treated with emergency URSL(URSL group) and 51 cases with middle or lower ureteral calculi were treated with ESWL (ESWL group).Clinicaldata of two groups,which came from our hospital the last three years,were analyzed retrospectively.To compare thesuccess rate of lithotripsy,pain release,clearance rate of stones after two weeks and complication incidence of the twogroups.Results The success rates of postoperative pain release,disposable lithotripsy,clearance of stones aftertwo weeks in URSL group were higher than that in ESWL group (95.56％ vs 78.43％,93.33％ vs 78.43％,97.78％ vs 82.35％,respectively,P ＜ 0.05).2 urinary tract infections were encountered in URSL group whereas 4 ca-ses in ESWL group suffered from macroscopic haematuria.There is no significant statistical difference between twogroups in complication,such asmacroscopic haematuria,ureter perforation,ureter tear,fever,urinary tract infectionand so on(P ＞ 0.05).Conclusions URSL is the better choice than ESWL for middle or lower ureteral calculiwith acute renal colic.so preferred ureteroscopy surgery has a certain clinical value of popularization in managementof those stones,which are longer than 10 mm in their diameter.
