Incidence of ureteral stricture after ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi.

Abstract

The results of our study have demonstrated that the success rate was not related to the stone dimension, but the time of operation was found to be increased with larger stones. Main risk factors for formation of ureteral stricture were impacted ureteral calculi and reasons which merits double-J catheter placement like mucosal damage, perforation, impacted calculi and high stone burden.
