A Comparative Study of Catheter-tip Culture with Foley Catheters of Different Materials / 대한비뇨기과학회지

ABSTRACT

In the recent 2 years, we performed 116 Foley catheter-tip(48 cases of latex, 35 cases of 100% silicone, 33 cases of Silastic) cultures from the male patients who did not have lower urinary tract infection before catheterization. The following result were obtained 1. The overall positive culture rate of rather-tip culture was 35.3%, and the positive culture rate of urine aspirated from proximal catheter wall just before removal of catheter was 20.6%. 2. The most common microorganism was E-coli in 29.3% and followed by Proteus spp. in 14.7%, Pseudomonas aeruginosa in 12.2%, Klebsiella pneumoniae in 9.8%, Staphylococcus aureus in 7.3%, Candida tropical in 7.3% in orders. 3. In comparison with duration of catheterization, the positive culture rates of catheter-tip of 3 different materials removed within one day were similarly low from 0 th 12%. However, the positive culture rate was much increased in latex-tip (70%) than silicone-tip (23%) and Silastic-tip (14.3%) which were removed between 2 to 4 days. More than 5 days of indwelling catheterization, the positive culture rates were latex-tip in 100%, silicone-tip in 47% and Silastic-tip in 57.1%.
