输尿管镜下钬激光治疗梗阻性急性肾功能衰竭

Holmium∶YAG laser lithotripsy under ureterscopy for treating urinary caluli combined with acute renal failure

目的:探讨输尿管镜下钬激光治疗上尿路结石梗阻并发急性肾功能衰竭的有效性和安全性。方法:应用输尿管镜直视下钬激光碎石术治疗输尿管结石梗阻并发急性肾功能衰竭患者12例。结果:术后患者血清尿素氮(BUN)、肌酐(Cr)均恢复正常或接近正常,尿量恢复正常,结石排净率92%(11/12)。结论:输尿管镜下钬激光治疗上尿路结石性梗阻并发急性肾功能衰竭具有安全、疗效可靠、损伤小、能同时处理双侧输尿管病变的优点,是急性梗阻性肾功能衰竭的有效治疗方法。

Objective：To study the therapeutic safety and effect of holmium：YAG laser lithotripsy for treating ureteral calculi combined with acute renal failure. Methods： Ureteroscopic holmium： YAG laser lithotripsy was used in 12 cases of ureteral calculi. Results： After the operation the serum BUN and Gr levels in the patients decreased to different degrees or returned to mormal and the stone free rate was up to 92% （11/12）. Conclusions： The ureteroscopic holmium：YAG laser lithotripsy can be the effective treatment for the upper urinary tract obstruction combined with acute renal failure, due to its safety and efficiency. It can also deal with the double sites of ureteral diseases.
