目的评价经皮肾镜气压弹道联合超声碎石术治疗肾结石的临床疗效。方法36例复杂性肾结石患者,在B超引导下行经皮肾镜气压弹道联合超声碎石清石术,观察临床治疗效果。结果患者均成功建立皮肾通道,进行Ⅰ期碎石清石。手术时间平均86min,结石处理时间55min。术后1周KUB检查,结石清除率达88.88%,4例结石残留小于1.0cm,辅以体外冲击波碎石治疗。结论经皮肾镜气压弹道联合超声碎石清石术是治疗肾结石的有效方法。
Objective To evaluate the clinical effect of percutaneous nephrolithotomy combined with ultrasonic lithotripsy on renal calculus. Methods Thirty - six patients with complicated renal calculi underwent percutaneous nephrolithotomy combined with ultrasonic lithotripsy and lithotripsy under B - guided ultrasound to observe the clinical effect. Results All patients had successfully established the renal access to stage Ⅰ gravel stone. The average operation time 86min, stone processing time 55min. KUB examination 1 week after operation, stone clearance rate of 88.88%, 4 cases of residual stones less than 1.0cm, supplemented by extracorporeal shock wave lithotripsy. Conclusion Percutaneous nephrolithotomy combined with ultrasonic lithotripsy is an effective method for the treatment of renal calculus.
