气囊尿管外固定囊对预防男性导尿患者泌尿道感染的临床研究

目的探讨气囊尿管外固定囊对减少男性留置导尿患者泌尿道感染的作用。方法将肿瘤内科男性导尿患者按导尿先后顺序随机分为观察组（100例）和对照组（100例）。对照组患者导尿成功后只应用导尿管的气囊进行导尿管膀胱内固定，不行尿管外固定；观察组患者在使用导尿管气囊进行膀胱内固定的同时，再应用气囊尿管外固定囊进行导尿管外固定，观察并比较两组患者留置尿管后第3、5、7天泌尿道感染发生情况。结果留置尿管后第3、5、7天，观察组患者的无症状菌尿症和泌尿道感染发生率分别为1.00%、0.00%，4.00%、2.00%，9.00%、3.00%；而对照组无症状菌尿症和泌尿道感染发生率分别为7.00%、3.00%，13.00%、7.00%，21.00%、13.00%，观察组的无症状菌尿症和泌尿道感染发生率均显著低于对照组（均P＜0.01）。结论气囊尿管外固定囊用于男性留置导尿患者，可以避免导尿管移动，有效降低泌尿道感染的发生，值得临床推广。

Effect of external fixation of balloon urethral catheter on preventing urinary tract infection in male patients

ObjectiveTo evaluate the effect of external fixation of balloon urethral catheter on preventing urinary tract infection in male patients. MethodsTwo hundred tumor male patients were randomly divided into observation group (100 cases) and control group (100 cases). Control group only applied balloon catheter to perform fixation of catheter inside bladder after the success of catheterization; observation group applied the external fixation of balloon catheter on the basis of inner fixation of catheter, urinary tract infection (UTI) on the 3rd, 5th and 7th day of catheterization in two groups of patients were observed and compared. ResultsOn day 3,5,and 7 in observation group, asymptomatic bacteriuria rate was 1.00%，4.00%，and 9.00% respectively, UTI rate was 0.00%，2.00%，and 3.00% respectively;in control group, asymptomatic bacteriuria rate was 7.00%, 13.00%, and 21.00% respectively, UTI rate was 3.00%，7.00%，and 13.00% respectively, asymptomatic bacteriuria rate and UTI in observation group was lower than control group respectively（P＜0.01）. ConclusionApplication of external fixation of balloon catheter for male patients with catheterization can avoid the moving of catheter, and reduce the occurrence of UTI.
