ABSTRACT

Objective To evaluate the effect of pneumatic ureteroscopic lithotripsy(URSL) for ureteral calculi.MethodsA total of 378 cases of ureteral calculi received URSL in our hospital by using F8/9.8 Wolf rigid ureteroscope and EMS Ⅱ pneumatic lithotripter(Switzerland).Among the cases,213 had calculi at the left side,158 at the right side,and 7 at the both sides;81 had the stones in the upper ureter,146 in the middle segment,and 158 in the lower part.Results In the cases,313 patients(320 sides) were cured after the first operation with a success rate of 82.8%(313/378).The success rates for the upper,middle,and lower ureteral calculi were 60.5%(49/81),84.2%(123/146),and 93.7%(148/158),respectively.The stones were removed completed in 1 to 8 weeks after the procedure.Fifteen patients were converted to an open surgery.In 3 patients,the URSL were stopped due to failure in placing the ureteroscope.The main postoperative complications in our series included perforation of the ureter(8 cases) and fever(13).Conclusions USRL is a safe,minimally invasive,and effective treatment.It should be the first choice for middle and lower ureteral calculi.
