Biofilm Formation UTI | Device: Long-term indwelling Foley catheter | Not Applicable |
A prospective, randomized, multi-center, post-market study in subjects that require a long-term indwelling Foley catheter.
A randomly assigned catheter will be inserted using standard techniques. Non-surgical subjects will rate the level of pain associated with the insertion procedure using the visual analog scale (VAS). A urine sample will be collected immediately after catheter insertion, in order to generate a baseline urinalysis and urine culture.
Follow-up visits will be performed on Day 28, or upon catheter removal, whichever occurs first. The catheter will be removed on Day 28 or earlier if clinically indicated. The removed catheter will be processed and sent to the core laboratory for analysis. Urine will be collected immediately prior to catheter removal in order to conduct urinalysis and urine culture. Subject will rate level of pain associated with the removal procedure using the VAS. The subject will also fill out a questionnaire about their experience with the catheterization immediately after catheter removal. Subjects will then be exited from the study.
