Comparison of Two Kinds of Extracorporeal Shock Wave Lithotripsy in Treatment of 108 Cases of Ureteral Calculi

Objective To evaluate of the clinical efficacy of two kinds of methods extracorporeal shock wave lithotripsy in treatment of ureteral calculi.Methods A retrospective analysis was conducted on the data of 108 patients with acute renal colic and ureteral stones(calculi diameter2 cm) from March 2011 to April 2013.The patients were divided into two groups.69 cases in A group underwent emergency positioning urography ureteral catheterization combined extracorporeal shock wave lithotripsy,39 cases in B group underwent emergency extracorporeal shock wave lithotripsy.Results A group:lithotripsy was successful in 63 cases among 69 cases at the first time,the first success rate was 91.33%(63/69),the second success rate was 94.2%(65/69),2 cases of retrograde ureteroscopy failed,2 cases of self-discharge after intubation stones,the recurrent renal colic rate was 14.3%(9/63),the use of analgesic drugs rate was 11.1%(7/63).B group:the first success rate of stone clearance rate was 74.4%(25/39),the second success rate of stone clearance rate was 87.2%(34/39),5 cases underwent ureteroscopy lithotripsy,the renal colic recurrence rate was 20.5%(8/39),the use rate of analgesic drugs was 15.4%(6/39).Conclusion Extracorporeal shock wave lithotripsy assisted by urography through retrograde ureteral catheterization has satisfying therapeutic effect in treatment of patients with ureteral calculi.
