宫颈癌根治术后留置尿管伴随尿路感染的临床分析

Urinary infection caused by post-operative urinary catheter reservation in crevice cancer

目的:探讨宫颈癌根治术后留置尿管伴随尿路感染的发生规律和病原菌分布。方法:将183例宫颈癌根治术后的患者作回顾性调查,将其分为留置尿管7～9d(Ⅰ组)56例,10～13d(Ⅱ组)61例和14d以上(Ⅲ组)66例,采用尿液细菌定量培养方法检测尿路感染的发生率,并分析其病原菌分布。结果:Ⅰ组、Ⅱ组、Ⅲ组尿路感染发生率分别为30.35%、49.18%、66.67%,平均为49.73%;大肠埃希菌(55.05%)、粪肠球菌(10.09%)和真菌(9.17%)是被检出的常见病原微生物;术后伴有尿路感染的91例患者膀胱功能恢复正常时间为7～68d(中位数14d),无尿路感染的92例患者为7～21d(中位数10d),两者差异具有显著意义(P<0.05)。结论:宫颈癌根治术后留置尿管伴随尿路感染平均发生率为49.73%,随着留置尿管时间的延长尿路感染发生率逐步升高,大肠埃希菌是最常见的病原菌,尿路感染是影响术后膀胱功能恢复的重要因素之—。

Objective:To discuss urinary infection and pathogenic bacteria of indwelling catheter post-operation with cervix cancer.Methods:183 patients with cervix cancer were investigated post-operation and divided into Ⅰ group(indwelling 7～9 d) 56 cases,Ⅱ groups(indwelling 10～13 d) 61 cases and Ⅲ group(more than 14 d) 66 cases,to test occurrence rate of urinary infection by quantitative for urine bacteria and discuss pathogenic bacteria distribution.Results:The occurrence rate of urinary infection in three groups are 30.35%、49.18%、66.67%,pathogenic microorganism include:Escherichia(55.05%),fecal bacillus(10.09%) and fungi(9.17%),the bladder return to normal function time for 91 patients with urinary infection post-operation were 7～68 d,the rest were 7～21 s,there was remarkable sense(P<0.05).Conclusion:The occurrence rate of urinary infection was 49.73%,Escherichia was the common pathogenic bacteria and urinary infection was the one of important factors to effect bladder return normal function.
