Clinical Experience of the Endoscopic Removal of Ureteral Stone without Anesthesia / 대한비뇨기과학회지

ABSTRACT

Use of the rigid ureteroscope has become widely accepted for the removal of ureteral calculi. We evaluated retrospectively the experience with rigid ureteroscopy from March 1992 to February 1993. We performed 68 ureteroscopies for the removal of stone in 67 patients, overall success rate was 86,8%. 52 stones were treated with sedatives only and l6 stones under the anesthesia. The success rates were 86.5% ( 45/52) and 87.5% (l4/l6) each. We failed to remove ureteral stones in 9 case, the failure of ureteroscope introduction was the most common cause of failure. The most common complication was the ureteral mucosal trauma, that was treated by indwelling of ureteral stent. We conclude that ureteroscopy may be an effective and useful procedure for the treatment of 1ower ureter stone (smaller than 10mm in size) under non-anesthesia.
