经皮肾镜碎石术后发热的综合分析

Comprehensive analysis of postoperative fever after percutaneous nephrolithotomy

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。

To investigate incidence of urinary tract infection and relative risk factors of postoperative fever after percutaneous nephrolithotomy.Clinical data of patients undergone percutaneous nephrolithotomy at our department from January 2007 to January 2017 were collected and the relative factors for postoperative fever were analyzed.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 fever.Multivariate analysis showed that positive urinary culture,staghorn calculus,diabetes,and pre-operative nephrostomy increased the risk of postoperative fever.The study shows that approximately 10%of patients developed fever post-PCNL despite receiving 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.
