目的评价经皮肾镜气压弹道联合超声碎石清石术(PCNL)治疗肾结石的疗效。方法2007年9月至2009年11月,B超引导下经皮肾镜下气压弹道联合超声碎石清石术治疗1019例肾结石患者。结果1019例患者均Ⅰ期成功建立经皮肾通道,手术时间20~130 min,平均85 min;结石处理时间16~140 min,平均63 min。结论经皮肾镜气压弹道联合超声碎石清石术治疗肾结石具有高效、耗时短、安全等特点,值得临床推广应用。
Objective To evaluate the efficacy of percutaneous nephrolithotomy combined with ultrasonic lithotripsy (PCNL) in the treatment of kidney stones. Methods From September 2007 to November 2009, 1019 cases of kidney stones were treated with B-ultrasonography guided pneumatic ballistic lithotripsy and ultrasound lithotripsy. Results All 1019 patients underwent stage Ⅰ successful percutaneous nephrectomy. The operation time ranged from 20 to 130 minutes with an average of 85 minutes. The stone treatment time ranged from 16 to 140 minutes (63 minutes on average). Conclusion Percutaneous nephrolithotomy combined with ultrasonic lithotripsy lithotripsy is characterized by high efficiency, short time-consuming and safety. It deserves clinical application.
