Comparative Study of Retroperitoneoscopy and Ureteroscope in the Treatment of Upper Ureteral Calculi

Abstract：Objective:To compare and analyze the clinical effects of retroperitoneoscopy and ureteroscope in the treatment of upper ureteral calculi. Method:100 cases with upper ureteral calculi treated by ureteroscope were selected as the control group,and another 86 patients treated by retroperitoneoscopy were selected as the experimental group,by method of random number table,calculus successfully removed rate,rate of calculus slidding into kidney which couldn’t remove,residual ratio of calculus after operation of two groups were compared.Result:The successful calculus removal rate of experimental group(100%) was significantly higher than control group(75.00%) after observation,rate of calculus slidding into kidney which couldn’t remove and residual calculus of experimental group(0,0) were significantly lower than control group(15.00%,10.00%),and disposable clearance rate of experimental group(100%) was significantly higher than control group(75.00%),differences between two groups were statistically significant(P<0.05).Conclusion:Retroperitoneoscopy has advantages of higher calculi removal rate,with no calculus slidding into kidney which couldn’t remove and without calculus residual,clearing the calculus more completely over ureteroscope,safe and reliable,it has better advantages that applying retroperitoneoscopy in upper ureteral calculi when it’s hard to use ureteroscope or the calculus is bigger.
