摘　　要：目的了解住院妇科恶性肿瘤患者术后尿路感染病原菌分布情况和影响因素,旨在为有效干预提供依据。方法通过感染监测和病原菌分离鉴定技术,对某医院住院妇科恶性肿瘤患者术后尿路感染情况和病原菌分布及相关危险因素进行统计分析。结果共分析恶性肿瘤患者238例,发生术后尿路感染56例,尿路感染的发生率为23. 53%。从尿路感染患者的尿标本中共分离培养出病原菌81株,其中大肠埃希菌所占分离菌株总数的50. 62%。多因素分析结果显示,年龄> 60岁、尿管插管次数> 2次、留置尿管时间> 7 d以及膀胱冲洗是导致妇科恶性肿瘤患者术后尿路感染的独立危险因素。结论妇科恶性肿瘤术后尿路感染的发生率较高,大肠埃希菌是最常见的病原菌,可针对感染危险因素制定有效干预措施。Objective To understand the distribution and influencing factors of pathogens of postoperation urinary tract infection in hospitalized patients with gynecological malignant tumors in order to provide evidence for effective intervention.Methods Statistical analysis was performed on the postoperative urinary tract infection status and pathogen distribution and related risk factors of patients with gynecological malignant tumors in a hospital by infection monitoring and pathogen isolation and identification techniques. Results A total of 238 patients with malignant tumors were analyzed. 56 cases of postoperative urinary tract infection occurred. The incidence of urinary tract infection was 23. 53%. A total of 81 pathogens were isolated and cultured from urinary specimens of patients with urinary tract infection,of which Escherichia coli accounted for50. 62% of the total isolates. Multivariate analysis showed that age > 60 years,frequency of urinary intubation > 2,time of indwelling urinary catheter > 7 d,and bladder irrigation were independent risk factors for postoperative urinary tract infection in patients with gynecological malignant tumors. Conclusion The incidence of urinary tract infection after operation of gynecological malignancy is high. Escherichia coli is the most common pathogenic bacteria,and effective intervention measures can be formulated according to the risk factors of infection.
