逆行上尿路腔内碎石术后并发急性尿源性感染的相关危险因素分析

目的探讨上尿路腔内碎石术后并发急性尿源性感染的危险因素。方法选取2013年2月至2014年11月在本院进行逆行上尿路腔内碎石术患者843例,按照术后是否发生急性尿源性感染进行分组,不发生感染的为A组(747例),发生感染的为B组(96例),收集并整理两组患者临床资料,采用单因素分析和logistic回归分析法分析逆行腔内碎石术后并发急性尿源性感染的危险因素。结果单因素结果显示年龄、性别、结石直径、手术时间、糖尿病、手术方式选择、术前是否应用抗生素为术后发生急性尿源性感染影响因素。Logistic回归分析结果显示女性、结石直径>2 cm、手术时间>90 min、糖尿病、尿白细胞>10个/HP、尿培养阳性为术后发生急性尿源性感染独立危险因素(P<0.05)。结论女性患者、结石直径>2 cm、手术时间>90 min、糖尿病、尿白细胞>10个/HP、尿培养阳性为患者术后并发急性尿源性感染的危险因素,此类患者术后应警惕急性尿源性感染的发生。

Analysis the risk factors of acute urinary infections after ureteroscopy lithotripsy

Objective To investigate the risk factors of acute urinary infections after ureteroscopy lithotripsy.Methods From February 2013 to November 2014,843 patients who underwent retrograde cavity lithotripsy in Guizhou medical university affiliated hospital were selected.All patients were divided into two gropus according to whether or not acute urinary infection occurred postoperativel,group A without infection(747 cases),group B with infection(96 cases).Two groups of patients with clinical data were collected,and the analysis of retrograde cavity gravel postoperative concurrent risk factor for acute urinary infection source was proformed by using single factor analysis and logistic regression analysis.Results Univariate results showed that age,sex,stone diameter,operation time,diabetes,surgical mode selection and preoperative antibiotics were the influencing factors for postoperative urinary infection.Logistic regression analysis showed that the independent risk factors for postoperative acute urinary infection were female,stone diameter>2 cm,operation time>90 min,diabetes,10>/HP of urinary leukocytes,and positive urine culture(P<0.05).Conclusions Female patients,>2 cm in stone diameter,>90 min in operation time,diabetes,10>/HP of urinary leukocyte,and positive urine culture are risk factors for postoperative acute urinary tract infection in these patients.Postoperative vigilance should be paid attention to the occurrence of urinary tract infection in these patients.
