Official Title: Retained Urine Volume and Bacteriuria in Traditional Versus Vented Urine Drainage Systems

Brief 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 Summary: 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.

Current Primary Outcome: Bacteriuria [ Time Frame: 7 days ]

Evidence of bacteriuria, a potential precursor to Catheter Associated Urinary Tract Infection (CAUTI), will be used to study the potential effect of the vented urinary drainage system intervention on CAUTI.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Retained Urine [ Time Frame: 7 days ]
    One potential source for the risk of developing a Urinary Tract Infection (UTI) is related to residual urine volume in the bladder
  • Presence of biofilms in catheter materials [ Time Frame: 7 days ]
    A key contributor to bacteriuria is formation of biofilms in the catheter and catheter tubing.


Original Secondary Outcome: Same as current
