经皮肾镜下气压弹道碎石加超声碎石取石术治疗复杂性肾结石

目的探讨经皮肾镜下气压弹道碎石加超声碎石取石术处理复杂性肾结石的疗效。方法2004年10月至2005年3月,采用经皮肾镜下气压弹道碎石联合超声碎石取石术I期治疗复杂性肾结石28例34侧。结果手术时间平均80 min,结石处理时间60 min,结石清除率91.1%;4例多发性结石或铸形结石患者远处肾盏内有直径小于1 cm残留小结石,辅助施行体外冲击波碎石治疗。所有病例随访1~3个月,均无严重手术并发症。结论经皮肾镜下气压弹道碎石加超声碎石取石术治疗较大的复杂性肾结石安全、高效、容易操作,且结石清除率高,值得临床推广应用。

Clinical efficacy of a combined pneumatic and ultrasound lithotripsy during percutaneous nephrolithotomy

Objective To define the safety and efficacy of a combined pneumatic and ultrasound lithotripsy during percutaneous nephrolithotomy.Methods From Oct 2004 to Mar 2005,34 renal units in 28 patients underwent percutaneous nephrolithotomy using a combined pneumatic and ultrasound lithotrite.Clinical data were analyzed retrospectively.Results The average time for whole surgery was 85 min and the time for complete stone clearance was 60 min,the rate of stone clearance was(91.1%),and 4 cases had a residual stone smaller than 1 cm due to an inaccessible location,and accessory therapy of ESWL was performed for the above 4 patients.No surgical complications occurred during lithotripsy after 1 to 3 month follow-up.Conclusion The lithotripsy of combining pneumatic and ultrasound is a safe and effective,easy and invasive operation for managing large and complex renal calculi.
