摘　　要：目的探讨引起泌尿外科住院患者尿路感染的危险因素。方法回顾性分析880例泌尿外科住院病历,将合并尿路感染者作为观察组,按1∶1选择同期无尿路感染泌尿外科患者作为对照组,对可能影响因素先进行单因素χ2t、检验;然后将单因素分析差异有统计学意义的变量进行多元逐步logistic回归分析。结果 880例患者中合并尿路感染60例,发生率为6.82%;单因素分析9个变量是影响尿路感染危险因素(P<0.05),采用lo-gistic回归分析,筛选出独立危险因素,按OR值的大小,依次为年龄大、有创诊治措施、合并其他疾病、预防使用抗菌药物。结论泌尿外科住院患者尿路感染发生率较高,影响因素较多,应针对上述因素予针对性预防措施。OBJECTIVE To investigate the high risk factors of urinary tract infection among inpatients in department of Urology.METHODS A total of 880 cases of urological medical records were analysised retrospectively.Patients with urinary tract infection were observed as a group,and the same number of urology patients without urinary tract infection were selected as the control group.Chi-square test and test were used to analysis possible single factors,and variables which had significant differences in univariate analysis were analysised by multivariable logistic regression.RESULTS Totally 60 cases were urinary tract infection,and the rate was 6.82%.Nine variables were risk factors effecting urinary tract infection in univariate analysis（P0.05）.Using logistic regression analysis,independent risk factors were selected according to the value of OR,which were older,invasive treatment measures,combined with other diseases,the prophylactic use of antibiotics.CONCLUSION Urinary tract infection had a higher incidence,and influenced by many factors among inpatients of department of urology.So,preventive measures should be taken by focusing on these factors.
