Objective To investigate incidence of urinary tract infection and relative risk factors of postoperative fever after percutaneous nephrolithotomy.Methods Clinical data of patients undergone percutaneous nephrolithotomy at our department from Jan-uary 2007 to January 2017 were collected and the relative factors for postoperative fever were analyzed.Results Of 535 patients,87 (16.2%) had positive urinary cultures in which 16(18.2%) had fever.In patients with negative urinary culture,39(8.8%) had fe-ver.Multivariate analysis showed that positive urinary culture,staghorn calculus,diabetes,and pre-operative nephrostomy increased the risk of postoperative fever.Conclusion The study shows that approximately 10% of patients developed fever post-PCNL despite re-ceiving antibiotic prophylaxis in our hospital.At the same time,if the existence of positive urinary culture,staghorn calculus,diabetes, pre-operative nephrostomy,etc.the risk of postoperative fever will be greatly increased.%目的 探讨经皮肾碎石术后尿路感染的发生率及术后发热的相关风险因素.方法 收集我科2007年1月至2017年1月经皮肾镜碎石术患者的临床资料,分析经皮肾碎石术后发热的相关因素.结果 535例患者中87例(16.2%)尿培养呈阳性,其中16例(18.2%)出现发热;尿培养呈阴性的患者中有39例(8.8%)出现术后发热.多因素分析显示阳性尿培养、鹿角形结石、糖尿病、术前肾造瘘等均增加术后发热的风险.结论 我院术前接受抗生素预防的经皮肾碎石的患者,术后发热的发生率在10%左右;若患者存在术前尿培养阳性、鹿角形结石、糖尿病、术前肾造瘘等情况时,其术后出现发热的风险将大大增加.
