Measuring Bladder Volumes With Ultrasound and Bladder Scanning in the ICU
ICU patients are at risk for catheter associated urinary tract infection. Frequently patients
can't tell clinicians if they need to void if the catheter is removed. If clinicians know
that an accurate volume measurement s of urine volume in the bladder can be obtained when the
catheter is removed, catheters could be removed earlier and more frequently and thus possibly
avoid an infection. For this study, measures with ultrasound (directly visualizing the
bladder to measure), bladder scanner (partially blind measure with placement of scanner over
the expected bladder location on the skin) and urine catheterized volume will be obtained.
The investigators also want to know if the technology is user dependent. The study will
include 2 levels of nurses RN and advanced practice RN (APRN) perform the bladder scanner. An
APRN and MD will conduct the ultrasound. Ultrasound is technology primarily used by
physicians but APRNs are using the technology technology more frequently. After these 4
measurements, the patient's nurse will perform an intermittent straight catheterization
(catheter inserted, urine drained, and catheter removed) as the gold standard comparison.

The purpose of this correlational descriptive study is to compare measured bladder volumes
with a bladder scanner (Verathon Prime), 3D ultrasound (Sono-Site II) and straight
catheterization in ICU patients with low urine output receiving dialysis and in ICU patients
unable to void.
Upon consent of patient or LAR, patient's age, gender and BMI with the assigned study code
number will be recorded on enrollment log. Study code number, patient initials and unit will
be written on bedside data collection sheet.
Sequence of 4 non-invasive (1-4) measurement will vary from day to day (see below)
1. MD performs bladder ultrasound and records volume on data collection sheet and places in
envelope
2. APRN performs bladder scanner and records volume on data collection sheet and places in
envelope.
3. APRN performs bladder ultrasound and records volume on data collection sheet and places
in envelope
4. Bedside RN performs bladder scanner and records volume on data collection sheet and
places in envelope
5. The study team will record the data from the straight catheterization that is performed
as part of clinical care.
6. APRN or research nurse will retrieve catheterization urine volume measurement from RN or
from chart and record on data collection sheet
Each enrolled patient will have these 4 measurements performed only on one day. Each
clinician research team member will record their result on a data collection form with the
study number, patient initials, day of week, clinician initials, observation of abdominal
fluid, and comment section for any other observations. The clinician research team member
will place the completed form for their measurement in an envelope with the study number on
the outside while the next clinician is in the room obtaining the next measure.
Data collection is complete after catheter volume is recorded.

- ICU patients without an indwelling urinary catheter and inability to void 6 hours post
urinary catheter removal or 6 hours after admission
