Objective To evaluate ureteroscopy for the treatment of ureteral stones.Method 56 cases of ureteral stones were treated by transureteroscopic frequency-doubled u-100 laser lithotripsy.Result: Among 56 cases of ureteral stones,52 cases had a statisfactory therapeutic effect with a successful rate of 92.8%.Ureter perforation occurred in 2 cases;stone free rate was 92.6% 2 weeks after;mean operating times was 22.7 minutes,no serious complications.Conclusion Transureteros copic u-100 laser lithotripsy is safe and effective,having less pain and rapid recovery.
