Abstract: ［Abstract］ Objective To report a self-made urethral catheter application and comparison with ordinary rubber catheter. Method Fifty?two cases with urethral injury（28 cases using self?made urethral catheter and 24 cases using normal rubber urethral catheter）and 58 cases without urethral injury（26 cases using self?made urethral catheter and 32 cases using normal rubber urethral catheter）were involved in this project. At the 3th，5th，10th day after catheterization，midstream urine were collected for urobacteriology culturing. Results In the patients with urethral injury， there were no statistical differences in urinary system infection between cases using self-made urethral catheter and using normal rubber urethral catheter at 3th and 5th day（P=0.149，and 0.054），but the rate was statistical difference in patients using normal rubber urethral catheter at 10th day（P=0.031）. The patients without urethral injury， there were no differences of urinary system infection rate between cases using self?made urethral catheter and using normal rubber urethral catheter at 3th，5th，10th day（all P>0.05）. Conclusion The self-made urethral catheter not only could be better than normal rubber urethral catheter used in catheterization，but also could reduce the urinary system infection rate during catheterization.

摘要： ［摘要］ 目的 报告我院研制的新型导尿管的使用效果及与普通橡胶导尿管在长期留置导尿患者中泌尿系感染发生率的差异。方法 52 例合并尿道损伤患者（使用新型导尿管组 28 例，普通导尿管组 24 例）以及 58 例不合并尿道损伤患者（使用新型导尿管组 26 例，普通橡胶导尿管组32 例），完成留置导尿术后，在第 3 天、第 5 天、第 10 天时取中段尿进行尿细菌学培养，比较不同组患者泌尿系感染发生率情况。结果 合并尿道损伤患者中，使用新型导尿管和普通橡胶导尿管的患者在第3 天、第5 天时，泌尿系感染发生率的差异不具有显著性（P 分别为0.149、0.054），而在第10 天的时，泌尿系感染发生率的差异具有统计学意义（P=0.031），使用普通橡胶导尿管患者的泌尿系感染发生率更高。不合并尿道损伤患者中，使用新型导尿管和普通橡胶导尿管患者的患者在第3 天、第5 天、第10 天时，患者泌尿系感染发生率的差异均不具有显著性（P 均>0.05），但是选择普通橡胶导尿管的患者泌尿系感染的发生率更高。结论 新型导尿管有效及实用，不增加长期留置导尿期间泌尿系感染的发生率。
