输尿管镜下气压弹道碎石术治疗输尿管结石305例临床分析

Clinical analysis of ureteroscopic minimally invasive technique in the treatment of ureteral calculi 305 cases

目的探讨输尿管镜下气压弹道碎石术(ureteroscopy swiss lithoclast,URSL)治疗输尿管结石的临床疗效。方法对应用输尿管肾镜行气压弹道碎石治疗输尿管结石305例临床资料进行分析。结果305例一次性原位碎石取石成功率为95.4%(291/305),其中上段结石87.5%(49/56),中下段结石97.1%(242/249),平均手术时间(20±10)min,平均术后住院时间(3±1)d。结论输尿管镜技术治疗输尿管结石效果确切、安全性高、创伤小、恢复快,是治疗输尿管中下段结石的首选方法。

[Objective] To evaluate the clinical effect of ureteroscopic ballistic lithoclast in the treatment of ureteral calculi. [Methods] 305 cases of ureteral calculi were treated with ureroscopic ballistic lithoclast. [Results] 305 cases were treated successfully in site with the cure rate of 95.5% at one time （87% in upper ureter, 97.4% in middle-lower ureter）. The mean time of operation was （20＋10） minutes. The mean time of in hospital after operation was （3＋1） days. [Conclusions] Treatment of ureteral calculi with ureteroscopic ballistic lithoclast is effective, safe, less invasive and recover soon. This method should be the first choice of treatment for middle and lower ureteral calculus.
