摘　　要：目的:总结上尿路结石合并尿细菌培养碳青霉烯类耐药肠杆菌科细菌(CRE)阳性患者行内镜手术后控制感染并发症的经验。方法:回顾性分析清华大学附属北京清华长庚医院2015年1月至2019年12月行内镜手术治疗的14例上尿路结石合并尿CRE阳性患者的临床资料。男7例,女7例。平均年龄58.2(34~71)岁。泌尿系B超、CT、KUB检查确诊为上尿路结石。肾结石13例,输尿管上段结石1例;结石位于左侧8例,右侧6例;单发结石3例,多发结石4例,鹿角形结石7例。14例术前尿细菌培养CRE均为阳性,其中大肠埃希菌7例,肺炎克雷伯菌6例,阴沟肠杆菌1例。术前共有3例发热患者,均行血细菌培养,其中阴性1例,CRE阳性1例(肺炎克雷伯菌),弗劳地柠檬酸杆菌阳性1例。术前经验性应用广谱抗菌药物(喹诺酮类和β内酰胺类)单药10例,联合用药1例;3例发热患者和1例既往有经皮肾镜取石术(PCNL)术后发热病史患者应用CRE目标性抗菌药物(替加环素、多黏菌素、磷霉素和氨基糖苷类)单药2例,联合用药2例。术前抗菌药物平均用药时间7.1(1~24)d,至体温正常,血白细胞、降钙素原(PCT)和C反应蛋白(CRP)正常,尿常规检查结果明显好转后行内镜手术。14例分别行PCNL和输尿管软镜碎石术(RIRS),2组的结石最大径分别为(31.5±10.2)mm和(10.8±2.6)mm。14例共行15次手术,RIRS 4次,PCNL11次,其中1例间隔1周先后行两次PCNL,1例行肾穿刺造瘘术后16 d行PCNL。PCNL均采用F24标准通道,负压超声碎石系统碎石;RIRS均采用外径F13~14的输尿管软镜鞘,采用200μm钬激光光纤碎石。术后2 h内和第1天复查血常规、血生化、PCT和CRP,术后第1~2天复查KUB,术后4周拔除双J管。结果:本组14例手术均顺利完成。PCNL和RIRS平均手术时间分别为(81.6±25.3)mins和(38.7±13.1)mins。术后经验性应用广谱抗菌药物单药7例;应用CRE目标性抗菌药物单药4例,联合用药4例。术后抗菌药物应用�Objective To evaluate the risk of infectious complication after endoscopic surgery for the treatment of upper urinary tract calculi combined with carbapenem-resistant Enterobacteriaceae(CRE)bacteriuria.Methods The clinical data of 14 patients who were diagnosed with upper urinary tract calculi combined with CRE bacteriuria and treated in Tsinghua University affiliated Beijing Tsinghua Changgung Hospital from January 2015 to December 2019 were analyzed retrospectively.There were 7 males and 7 females,aged from 34 to 71 years old(mean 58.2 years old).The diagnosis was confirmed by ultrasonography,CT or abdominal X-ray.Fourteen cases underwent 15 procedures,including 4 RIRS and 11 PCNL.One patient underwent 2 PCNL procedures at an interval of 1 week,and 1 patient underwent PCNL 16 days after nephrostomy.There were 13 cases of renal calculi and 1 case of upper ureteral calculi.Stones were found on the left side in 8 cases and the right side in 6 cases.There were 3 cases of solitary stone,4 cases of multiple stones and 7 cases of staghorn stone.The maximum diameter of stones was(31.5±10.2)mm in patients who underwent PCNL,and(10.8±2.6)mm in patients undergoing RIRS.The complete blood count,blood biochemistry,procalcitonin and C-reactive protein were tested postoperatively on the same day of the procedure and 1 day after the procedure.Abdominal X-ray was performed 1-2 days postoperatively,and the ureteral stent(double J)was removed 4 weeks after the procedure.Fourteen patients with CRE bacteriuria underwent 15 endoscopic procedures.Urine culture identified 7 cases of Escherichia coli,6 cases of Klebsiella pneumoniae and 1 case of Enterobacter cloacae.Preoperative blood culture was performed in 3 cases,of which 1 case was negative and 1 case was Klebsiella pneumoniae positive.Before operation,11 cases were empirical treated with broad-spectrum antibiotics,including monotherapy in 10 cases and drug combination therapy in 1 case.Sensitive antibiotics against CRE were prescribed in 4 cases preoperatively,including monoth
