[Treatment of ureteral calculi with rigid ureteroscopy. Report of 67 cases]

To evaluate the results obtained by rigid ureteroscopy to treat ureteral calculi.Between May 1998 and September 2000, 63 patients underwent 67 rigid ureteroscopies (URS) with three endoscopic retreatments and one bilateral URS, for 48 distal, ten mid and nine proximal ureteral calculi.After URS 77.6% of the patients were free of the stones. Success rate was respectively 85.4%, 60% and 55.5% in distal, mid and proximal uretero. Morbidity was 10.4% and there have been one stricture treated by endoscopy.Our series demonstrates that rigid URS is safe and effective procedure to treat distal, ureteral calculi. Thus, it should be considered a treatment of choice for distal ureteral calculi.
