目的探讨应用B超引导,经皮肾穿刺造瘘,弹道联合超声碎石清石治疗复杂性肾结石的临床效果。方法回顾性分析2006年7月至2008年4月应用超声引导对41例肾结石患者进行经皮肾镜碎石术(PCNL)治疗的临床资料。结果41例中4例穿刺失败的3例改开放手术,1例放弃并自动出院,37例患者成功建立皮肾通道,32例行Ⅰ期碎石,5例Ⅱ期碎石。结石直经1.5~6.9cm,平均手术时间104min,结石处理时间为15~150min。完全清除结石22例,15例有残余结石,清石率59.5%。结论B超引导经皮肾穿刺造瘘弹道联合超声碎石清石治疗复杂性肾结石具有高效、安全的特点,值得临床进一步推广应用。
Objective To investigate the clinical effect of B-guided, percutaneous nephrolithotomy and ballistic lithotripsy in the treatment of complicated renal calculus. Methods The clinical data of 41 patients with renal calculus underwent percutaneous nephrolithotomy (PCNL) guided by ultrasound guided from July 2006 to April 2008 were retrospectively analyzed. Results In 4 of 41 cases, 3 cases failed to be punctured and changed to open surgery. One case was abandoned and discharged automatically. Thirty-seven cases were successfully established skin nephropathy, 32 cases were stage Ⅰ gravel and 5 cases were stage Ⅱ gravel. Stone straight through 1.5 ~ 6.9cm, the average operation time 104min, stone processing time is 15 ~ 150min. Complete removal of stones in 22 cases, 15 cases of residual stones, clear stone rate of 59.5%. Conclusion B-guided percutaneous nephrostomy and fistula combined with ultrasonic lithotripsy stone complex treatment of renal stones with high efficiency and safety characteristics, it is worth further clinical application.
