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.
