The Efficacy and Safety of Simultaneous Use of Wire Stone Basket and Pneumatic Lithotripter Probe in the Treatment of Ureteral Stones: Randomized Control Trial

Abstract

Introduction:  A routine treatment of ureteral stones is using ureteroscopic lithotripsy, a common problem of which is retropulsion of the stone to the renal pelvis and calyces that reduces the rate of lithotripsy’s success. In this study, we aim to investigate the safety and success of using wire basket to hold the stones along with pneumatic lithotripstic probe in endoscopic lithotripsy of ureteral stones. Methods: Patients with ureteral stone were randomly divided to groups A and B. Group A (control) undergone lithotripsy without basket and group B (case) with wire basket along with pneumatic lithotripsy. In addition to demographic and clinical data, rate of success, retropulsion and residual stone with a size of greater than 3 mm were collected, before, during and after lithotripsy. Additionally, the total duration of lithotripsy and ureteral traumatic side effects was also recorded in both groups. All the patients were followed up until their discharge. Data was analyzed using SPPSS ve. 20.  Results: There was no significant difference between groups by the point of demographic data. When compared together, there was no significant difference between the location, side and size of the stone and duration of the lithotripsy in both groups. The rate of lithotripsy success was significantly higher in the case group. The incidence of retropulsion and need for a secondary intervention was significantly higher in the control group.  We didn’t have any ureteral trauma in neither control nor case group. Conclusion: Based on the results of this study, using wire basked as an anti retropulsion device increases the stone free rate in addition to it’s easy applicability, So it can be useful in treatment of ureteral stone.
