目的探讨B超定位下微创经皮肾镜气压弹道碎石术(MPCNL)治疗肾结石的疗效。方法采用B超定位下微创经皮肾镜气压弹道碎石术治疗肾结石35例。结果 35例患者均成功建立工作通道,手术过程顺利,无一例改开放手术。一次性结石取净31例(88.6%),4例术后残石行ESWL及中药排石治疗。手术时间45~110min,平均76 min。术中出血50~200 ml。结论 B超定位下微创经皮肾镜气压弹道碎石术治疗肾结石是一种安全、疗效确切的微创治疗方法 。
Objective To investigate the curative effect of minimally invasive percutaneous nephrolithotopic pneumatic lithotripsy (MPCNL) in the treatment of renal calculi under B-ultrasound. Methods 35 cases of renal calculus were treated with minimally invasive percutaneous nephroscopic pneumatic lithotripsy under B-ultrasound. Results All the 35 patients successfully established the working channel, and the operation procedure went smoothly without any change of open surgery. Thirty-one cases (88.6%) were treated with one-off stones, and ESWL was performed in 4 cases with postoperative stone residue. Operation time 45 ~ 110min, an average of 76 min. Intraoperative bleeding 50 ~ 200 ml. Conclusion The minimally invasive percutaneous nephrolithotrude pneumatic lithotripsy for the treatment of kidney stones with B-ultrasound is a safe and effective minimally invasive treatment.
