Monthly urine cultures were analyzed at the University of Alberta Department of Medical Microbiology and Infectious Diseases to determine whether single-use sterile catheters and clean technique reduced the incidence of bacterial colonization in those using long-term intermittent self-catheterization. Thirty subjects with spina bifida, ages 3 years to 16 years, entered a crossover study with random assignment to 6 months of sterile single-use catheters or clean reused catheters. Seventeen subjects were catheterized by a parent or caregiver; 13 were responsible for self-catheterization and cleaning of the catheters. Six months of descriptive data were also collected at Alberta Children's Hospital from a similar group of subjects with spina bifida who used sterile catheters only. In the crossover group, 38% of all urine cultures were positive regardless of whether sterile single-use or clean reused catheters were employed. The other group using only sterile catheters had a 36% positive culture rate. No difference in positive cultures was found between males and females or between children who catheterized themselves and children whose parents catheterized them. The authors concluded that plastic urethral catheters may be reused.
艾伯塔大学医学微生物学与传染病系对每月的尿培养进行了分析，以确定一次性无菌导尿管和清洁技术是否能降低长期间歇性自我导尿者的细菌定植发生率。30名年龄在3岁至16岁的脊柱裂患者进入了一项交叉研究，随机分配接受为期6个月的无菌一次性导尿管或清洁再利用导尿管。17名受试者由父母或护理人员进行导尿；13名负责自我导尿和导尿管清洁。艾伯塔儿童医院还从一组类似的仅使用无菌导尿管的脊柱裂受试者中收集了6个月的描述性数据。在交叉组中，无论使用无菌一次性导尿管还是清洁再利用导尿管，所有尿培养中有38%呈阳性。另一组仅使用无菌导尿管的培养阳性率为36%。在男性和女性之间，以及自我导尿的儿童和由父母导尿的儿童之间，培养阳性情况没有差异。作者得出结论，塑料尿道导尿管可以重复使用。
