A comparison of the microbiologic profile of indwelling versus external urinary catheters

Am J Infect Control. 2014 Jun;42(6):682-4. doi: 10.1016/j.ajic.2014.02.028.


We studied the microbiology reports of urine cultures collected from external (condom catheters) versus indwelling (Foley) catheters. The equal prevalence of Enterobacteriaceae and Enterococci in samples from both catheter types calls into question the practice of switching from indwelling to external catheters to decrease catheter-associated bacteriuria.

Keywords: Bacteriuria; Catheter-associated UTI.
