目的:探讨固定胶带+细绳固定法固定导尿管对经皮肾镜取石术患者术后导尿管相关性尿路感染（CAUTI）和舒适度的影响。方法:选取2018年1月至2019年4月郑州大学第一附属医院泌尿外科接受经皮肾镜取石术的泌尿系结石男性患者106例作为研究对象，按照随机数字表法分为试验组55例和对照组51例。对照组对导尿管采用高举平台法固定，试验组对导尿管采用固定胶带+细绳固定法固定。比较2组患者CAUTI发生率以及导尿管外露长度和导尿管相关不适症状随时间变化的情况。结果:研究过程中试验组3例，对照组1例导尿管留置时间<1周；试验组1例，对照组2例因大出血改为三腔导尿管膀胱冲冼而退出，最终试验组纳入51例，对照组纳入48例。试验组CAUTI发生率为3.9%（2/51），低于对照组的16.7%（8/48），差异有统计学意义（χn 2=4.42，n P<0.05）。插管后第3、5、7天，试验组导尿管外露长度分别为（17.76 ± 1.41）、（17.12 ± 1.28）、（16.49 ± 1.63）cm，长于对照组的（16.04 ± 1.96）、（15.81 ± 1.78）、（15.29 ± 1.96）cm，差异有统计学意义（n t = 5.00、4.17、3.32，均n P<0.05）；插管后第3、5、7天，试验组导尿管相关性不适症状评分分别为（0.82 ± 0.09）、（0.53 ± 0.07）、（0.49 ± 0.08）分，低于对照组的（1.17 ± 0.23）、（0.92 ± 0.09）、（0.77 ± 0.11）分，差异有统计学意义（n t = 2.10、2.88、2.46，均n P<0.05）。n 结论:固定胶带+细绳固定法固定导尿管可降低泌尿系结石患者CAUTI发生率，增加导尿管的稳定性，并能降低患者的不适感。“,”Objective:To probe into the influence of adhesive tape and string fixation on postoperative catheter-associated urinary tract infection(CAUTI) and comfort degree of patients undergoing percutaneous nephrolithotomy.Methods:A total of 106 cases of male urinary tract calculi patients undergoing percutaneous nephrolithotomy in Urology Department of First Affiliated Hospital of Zhengzhou University from January 2018 to April 2019 were selected. They were divided into the experimental group (55 cases) and the control group (51 cases) by random digits tbale method. The control group received platform fixation method, the experimental group implemented adhesive tape and string fixation method for catheter fixation. The incidence of CAUTI were compared between two groups, the catheter exposed length changes and catheter-related discomfort changes was also compared.Results:The incidence of CAUTI were 3.9%(2/51) in the experimental group, significantly lower than 16.7%(8/48) in the control group, the difference was statistically significant (n χ2=4.42, n P<0.05). After 3 days, 5 days and 7 days of indwelling catheter, the catheter exposed length were (17.76 ± 1.41), (17.12 ± 1.28), (16.49 ± 1.63) cm, significantly longer than those in the control group (16.04 ± 1.96), (15.81 ± 1.78), (15.29 ± 1.96) cm (n t=5.00, 4.17, 3.32, all n P<0.05); the catheter-related discomfort symptom scores at above mentioned time were 0.82 ± 0.09, 0.53 ± 0.07, 0.49 ± 0.08, significantly lower than those in the control group (1.17 ± 0.23, 0.92 ± 0.09, 0.77 ± 0.11), the differences were statistically significant (n t=2.10, 2.88, 2.46, all n P<0.05).n Conclusions:Adhesive tape and string fixation method for catheter fixation can reduce the incidence of CAUTI of patients with urinary tract calculi, improve the catheter fixed state as well as reduce the patient′s catheter-related discomfort.
