Evaluation of Male and Female External Catheters for Urine Output Monitoring in the ICU

July 31, 2026 updated by: C. R. Bard

A Prospective, Observational Pilot Study Evaluating the Performance and Clinical Acceptance of PureWick® When Used in the ICU for Urine Output Monitoring

The goal of this observational pilot study is to learn about the ability of the PureWick® Flex Female External Catheter and the PureWIck® Male External Catheter to capture urine output in adult ICU patients compared to indwelling urinary catheters. The study will also gather feedback from ICU clinicians about the suitability of PureWick® urine output data to inform clinical decision-making.

Study Population

Adult ICU patients requiring urine output monitoring as part of their fluid management strategy

Description

Inclusion Criteria:

  1. Adult patients =18 years at the time of ICU admission
  2. Female and Male Patients requiring urine output monitoring
  3. Provision of a signed and dated informed consent form

Exclusion Criteria:

  1. Frequent episodes of bowel incontinence without a fecal management system in place; or
  2. Has moderate to heavy menstruation or vaginal bleeding and cannot use a tampon or menstrual cup; or
  3. Has urinary retention; or
  4. Is agitated, combative, restless, and/or uncooperative and may remove or dislodge the external catheter or indwelling catheter; or
  5. Presence of moderate to severe insensible fluid loss, including but not limited to: Diaphoresis; Anasarca; or, based on the investigator's assessment, is unlikely to provide accurate urine leakage measurements on the pad due to the presence of other fluids (e.g. blood, stool); or
  6. Any other condition that, in the opinion of the investigator, would preclude them from participating in the study

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Urine Capture Rate
Time Frame: Approximately every 4 hours for up to 72 hours
Capture rate is calculated as the weight of captured urine (post-void graduated cylinder weight - pre-void graduated cylinder weight) / total urine volume (captured urine + leaked urine (post-void absorbent pad weight - pre-void absorbent pad weight) * 100
Approximately every 4 hours for up to 72 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
ICU Clinician Acceptability
Time Frame: From start of the observation period to the end of the observation period, up to 72 hours
A survey completed by ICU clinicians to assess the suitability of using urine output measurement data to inform clinical decision making on a 4-point Likert scale with lower scores indicating a better outcome.
From start of the observation period to the end of the observation period, up to 72 hours
