经皮肾镜气压弹道超声碎石术治疗复杂性肾结石

Treatment of complicated renal calculi under percutaneous nephrolithotomy with ultrasonic and pneumatic lithotripter

目的探讨经皮肾镜经皮肾镜气压弹道超声碎石术治疗复杂性。肾结石的方法及疗效。方法采用瑞士EMS第三代气压弹道联合超声碎石机治疗512例复杂性肾结石患者，对其临床资料进行回顾性分析。结果所有患者均Ⅰ期建立F24皮肾通道Ⅰ期碎石，肾结石清除率87．5％。平均手术时间120min。本组中无输血及术后迟发型大出血、液气胸、肠道损伤等并发症。结论经皮肾镜下气压弹道联合超声碎石术处理复杂性肾结石是高效安全的，明显提高结石的清除率，具有对患者创伤小、恢复快、缩短住院时间等优点，并在对残留结石的再次治疗方面有较大的优越性。

Objectives To evaluate the methods and efficacy of percutaneous nephrolithotomy with ultrasonic and pneumatic lithotripter （ EMS Ⅳ） in the treating of complicated renal caleali. Methods 512 renal unites with complicated renal calcali received percutaneous nephrolithotomy performed by ultrasonic and pneumatic litho- lripter. Results 89.5 % stone - free rate wan achieved one - stage minimally invasive percutaneous nephrolithotomy. Average operative time was 115 minutes. Neither the pheumothorax nor the bowel hurts complications were noted in the patients. Conclusions Invasive percutaneous nephrolithotomy is safe and effective in the treatment of major renal calcalli. High stone free rate, less invasion easy recovery and shot hospitalization stay are its merits. It also has advantages of treating the patients with residual calculi.
