Experience of Ureteroscopic Removal of Ureteral Stone in 35 Cases

Park, Tae Sik; Kim, Dong Han

Abstract

Ureteroscopic removal of stone is now an established technique for the management of ureteral stones and can be done under direct vision using flexible grasping forceps or stone baskets with increased safety and efficacy. A clinical study of our 35 cases of ureteroscopic removal of ureteral calculi was performed. Only one among 4 cases of mid and upper ureteral calculi and 27 among 31 cases of lower ureteral calculi were removed successfully. Therefore the overall success rate was 80 %(28 among 35 cases). Complications occurred in 6 cases : a case of ureteral avulsion, a case of ureteral separation, 2 cases of uncomplicated urinary tract infection and 2 cases of ureteral perforations. We conclude that ureteroscopic removal of ureteral stone under direct vision can be done safely and be the first choice of management for the lower ureteral surgical calculi, but the antegrade removal of stone through percutaneous nephrostomy tract may be preferable for the upper and mid ureteral calculi.
