微创经皮肾镜技术在肾结石开放手术中的应用

Application of minimally invasive nephrolithotomy in the open surgery for patients with renal calculi

目的:评价微创经皮肾镜取石(minimally invasive Percutaneous nephrolithotomy,MPCNL)技术在特殊肾结石患者开放手术中的应用价值。方法:开放手术中经肾穿刺、扩张,利用输尿管镜碎石、取石治疗8例患者。结果:穿刺均一次成功,一次取尽结石7例,1例残留结石再次经造瘘管取尽,术后恢复理想,无严重并发症发生。结论:肾结石开放手术中配合使用MPCNL技术具有创伤小、提高结石取尽率等优点,特别是在术前估计不足,应急的状况下,术中使用MPCNL技术不失为一种行之有效的补救措施。

Objective：To evaluate the application of minimally invasive percutaneous nephrolithotomy（MPC-NL）in the open surgery for patients with renal calculi Methods：Kidney were punctured and distended successfully, then, calculis were treated by ureteroscope tithotripsy in 8 cases. Results： All cases were stabbed successfully in one time, seven patients had complete clearance of the stone on postoperative imaging, one patient＇s remnant calculls were cleaned through renal stoma later. All patients recovered well without any serious complications. Con- clusions： It is an effective remedy measure combining with MPCNL in the open operation, which causes less trauma and improves stone-free rates, especially under the condition of emergency and insufficient preoperative evaluation.
