Summary

The purpose of this study is to see if there are differences in urine drainage between two types of indwelling bladder catheter systems (Foley catheter) in hospitalized patients. The difference between the two catheters is that one catheter is vented (the study catheter) and the other is a standard non-vented catheter. The vented catheter may drain urine better than a standard non-vented catheter. If a vented catheter drains the bladder better than a non-vented catheter it may lower the risk of retained urine in the bladder which could help prevent urinary tract infections.

Detailed description

During hospitalization, while in the surgical intensive care unit beginning the day after surgery, measurements of the subject's urine drainage system will be taken at daily study visits: retained urine volume, dependent loops, incidence of bacteriuria, and thigh diameter.

Conditions

• Bacteriuria

Interventions

Type	Name	Description
DEVICE	Vented urinary drainage system	This group will be catheterized with a vented urinary drainage system. Several data sets will be evaluated to compare the two arms of the study: retained urine volume, the difference (ΔH) in meniscus heights in the dependent loops, time necessary for drainage of dependent loops, and incidence of bacteriuria.
DEVICE	Non-vented urinary drainage system	This group will be catheterized with a non-vented urinary drainage system. Several data sets will be evaluated to compare the two arms of the study: retained urine volume, the difference (ΔH) in meniscus heights in the dependent loops, time necessary for drainage of dependent loops, and incidence of bacteriuria.
