Objective: To elevate the clinical use of urteroscope pneumatic lithotrity on the trement of ureteral stones. Methods: From Mary 1996 to March 2004 298 patients with uretericlithias were treated with lithotripsy of ureteroscopy. Results: 283 cases(94.93%)got success in orthotopic lithotriptics,success rate of upper segment calculi in ureter was 87.04%, middle segment was 95.58%, lower segment was 97.71% mean lithotriptic time was (15.7±2.8) min. Conclusions: With minimal invasion and pain, this procedure is safe and effective for ureteral calculi,being probably the treatment of first choice.
