Abstract

Rigid ureteroscopy is now an established technique for the management of ureteral stones and the diagnostic procedure of ureteral lesions. The results of ureteroscopic stone removal were reviewed in 153 patients (1 patient ; bilateral). From October 1989 to August 1990, 163 patients underwent ureteroscopic removal of ureter stones. There were 53 female and 100 male patients between 17 and 72 years old. In all patients with ureteral stones surgical intervention was indicated for the obstruction with deteriorating kidney function, infection or severe and prolonged pain. All procedures were performed under epidural anesthesia. Stones were extracted, using grasping forceps or stone baskets with or without electrohydraulic lithotriptor (EHL) under direct visual control. Success of ureteroscopic removal was related to the location of the calculus : 98.2% in the distal, 88.2% in mid and 79.2% in the proximal ureter (overall success rate was 94.2% ). The associated number of complications was low, with most patients being treated conservatively. We conclude that ureteroscopic removal of ureteral stone under direct vision can be done safely and be the first choice of management for the ureteral calculi.
