The incidence of catheter-associated urinary tract infections (UTIs) becomes higher with prolongation of the indwelling period of a catheter. As to the entry of bacteria, ascending UTIs have now attracted attention. In the present study. the metal area was examined bacteriologically and the possibility to use antiseptics for blocking the route of developing infections was investigated. The subjects included 72 patients with an indwelling, urethral catheter inserted post-operatively. These patients were divided into three groups treated with once or twice daily application of povidone-iodine or once daily application of povidone-iodine cream. In these groups, the relation between changes in isolation of bacteria from the meatal area and the incidence of UTI was evaluated. It was found that reduction in bacterial count by antisepsis is effective to prevent ascending UTIs. Moreover, once daily application of povidone-iodine was proven to be effective in male patients. The effective antisepsis in females was twice daily application of povidone-iodine.
导尿管相关尿路感染（UTIs）的发生率会随着导尿管留置时间的延长而升高。关于细菌的侵入，上行性尿路感染目前已受到关注。在本研究中，对尿道口区域进行了细菌学检查，并研究了使用防腐剂阻断感染发展途径的可能性。研究对象包括72例术后留置尿道导尿管的患者。这些患者被分为三组，分别接受每日一次或两次聚维酮碘治疗，或每日一次聚维酮碘乳膏治疗。在这些组中，评估了尿道口区域细菌分离变化与UTI发生率之间的关系。结果发现，通过防腐措施减少细菌数量对预防上行性尿路感染有效。此外，已证明每日一次应用聚维酮碘对男性患者有效。对女性有效的防腐措施是每日两次应用聚维酮碘。
