低压灌注输尿管镜碎石术治疗输尿管结石

目的探讨低压灌注经尿道输尿管镜碎石术的可行性，分析其疗效和手术早期并发症的发生率。方法对2008年8月至2009年7月在我院行输尿管镜碎石术的224例患者随机分为低压灌注组和高压灌注组．分别在低压灌注和高压灌注下行输尿管镜碎石术。比较两组手术时间、疗效和术后早期并发症的发生率。结果低压灌注组和高压灌注组手术时间无明显差异，低压灌注组结石上移肾盂的发生率以及术后肾区严重疼痛、一过性肾功能减退、菌血症等早期并发症的发生率明显低于高压灌注组。结论低压灌注下行输尿管镜碎石取石术在临床上是可行的。避免高压灌注可减少结石上移至肾盂的机会，有效预防术后早期并发症。

Ureteroscope under Low Pressure Irrigation to Treat for Ureteral Calculus

Objective To approach the feasibility ofureteroscope under low pressure irrigation to treat for ureteral calculus, and to analyze its curative effect and the incidence rate of its early complications. Methods The study included 224 patients treated with uretero- scope between August 2007 and July 2008, 112 patients under low pressure irrigation, and other 112 ones under high pressure irrigation. We compared the differences between two sets. Result The operation time of two sests was approximately alike, and curative effect and incidence rate of early complications was different. Conclusion Ureteroscope under low pressure irrigation to treat for ureteral calculus is feasi- ble. Low pressure irrigation can decrease the chance of calculus shifting and the incidence rate of early complications.
