彩超引导下经皮肾镜碎石术治疗不积水肾结石

Color doppler ultrasound guided percutaneous nephrolithotomy for treatment of renal calculi in non-dilated collecting system

目的:探讨彩超引导下经皮肾镜术治疗不积水肾结石的应用价值,总结技术要点。方法:55例不积水肾结石患者,在彩超引导下建立标准经皮肾通道,采用EMS第四代碎石清石系统清除结石。结果:全部患者均成功建立通道,一期完成手术,一期结石清除率90.9%(50/55),2例残石较多者行二期PCNL,3例术后ESWL治疗。所有患者均未输血以及介入栓塞治疗。结论:彩超引导下行经皮肾镜术治疗不积水肾结石,可以有效降低术中、术后严重出血,安全可靠。

Objective：To evaluate the clinic application value of color doppler ultrasound-guided percutaneous nephrolithotomy for treatment of renal calculi in non-dilated collecting system, and summarize the main points of colour doppler ultrasound-guided technology. Method：Fifty-five cases of renal calculi in non-dilated collecting sys- tem were performed by percutaneous nephrolithotripsy. The standard renal channel was estabilished under the guidance of colour doppler ultrasound. Result..Percutaneous renal access was successfully established and immediate phase I Lithotripsy was performed in all patients. Stones were cleared in 50 out of 55 cases（90.9 % ）during immedi- ate phase I lithotripsy. 2cases with some residual stone fragments received second PCNL,others（3 cases）received extracorporeal shock wave lithotripsy. No patient received blood transfusion or interventional emholization. Conclu- sion：Color ultrasound guided percutaneous nephrolithotomy is an effective and safe treatment for renal calculi in non-dilated collecting system. This technology can effectively reduce heavy blood loss during and after operation.
