[Experience in transurethral ureterolithotripsy using a rigid ureteroscope].

We report our experience of transurethral ureterolithotripsy using a rigid ureteroscope on 18 ureteral calculus patients between November, 1985 and July, 1986. The stones could be successfully removed in 3 of the 10 cases of upper ureteral calculi and in all 8 cases of lower ureteral calculi. In this series, transurethral ureterolithotripsy proved to be valuable for the lower ureteral calculus. However, the device still needs to be improved for upper ureteral calculi.
