微创经皮肾穿刺取石术治疗复杂性肾结石的术后并发症危险因素研究

Study on the risk factors of postoperative complications of minimally invasive percutaneous nephrolithotomy in the treatment of complex renal calculi

目的:对微创经皮肾穿刺取石术治疗复杂性肾结石的术后并发症危险因素进行研究、分析。方法:收治实施微创经皮肾穿刺取石术治疗复杂性肾结石患者170例,在术后2个月对其发生的并发症的相关危险因素进行分析。结果:发生术后并发症19例。术后并发症的发生与体重指数、体外冲击波碎石术史、结石大小、术前尿路感染及手术时间有直接关系(P<0.05);与性别、年龄无直接关系(P>0.05)。结论:手术时间、术前中段尿细菌培养和结石大小是术后发生并发症的重要危险因素。

Objective：To study the risk factors of postoperative complications of minimally invasive percutaneous nephrolithotomy in the treatment of complex renal calculi.Methods：170 patients with complex renal calculi treated by minimally invasive percutaneous nephrolithotomy were selected.The risk factors for the complications were analyzed at two months postoperatively.Results：19 patients had postoperative complications.The incidence of postoperative complications was directly related to body mass index,extracorporeal shock wave lithotripsy history,stone size,preoperative urinary tract infection and operation time（P〈0.05）.And sex,age was not directly related（P〈0.05）.Conclusion：The operation time,preoperative urinary bacterial culture and stone size are important risk factors for postoperative complications.
