Objective:To observe clinical effect and complications of treating ureterolith through aerodynamic trajectory lithotrity by ureterorenoscope(URS).

观察经输管肾镜行道碎石治输管结石的临床并发症。

Conclusion: Under ureter mirror barometric pressure trajectory lithotrity security.Damages slightly.The effect is obvious.

结论输管镜下道碎石术安全,损伤小,果确切。
