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

观察经输管肾镜行气压弹道疗输管结床疗效及并发症。

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

结论输管镜下气压弹道术安全,损伤小,效果确切。
