Urodynamic Testing


Urodynamics is the study of how the body
stores and releases urine. The test measures
the function of your bladder, urethra, and
pelvic floor muscles. Bladder pressure,
urine flow, and muscle movement are
assessed as your bladder fills and empties.
This test is widely used in adults and
children. It provides your doctor with
information on how to treat your bladder
symptoms.

Before the Test
The test takes place in the Urology Clinic.
Expect the test to take 1½ to 2 hours. Arrive
at the clinic ready to urinate. The nurse will
ask you to empty your bladder once you are
called back into the room. If you are on a
catheterization program, stay on your
schedule. There is no extra prep needed,
unless you have been told to do so by your
doctor or nurse. Please eat and drink
normally before this test.

During The Test
You may be asked to urinate in a special
toilet to measure the force of your urine
flow, the time it takes to pass urine and the
amount of urine in your bladder. Please
wait for the nurse to tell you when to empty
your bladder for this test.

A small soft tube (catheter) will be placed in
your bladder though your urethra. A small
pressure sensor may be put just inside your
rectum. This will not hurt. You may also
have small sticky pads placed next to your
rectum to measure the muscles of your
pelvic floor.

Once the tubes and pads are in place, they
will be connected to a computer. Your
bladder will be filled slowly with sterile
water. The nurse will ask you questions
about the sensations you are feeling as your
bladder fills. When you have a strong urge
to pass urine, you will be asked to relax and
empty your bladder with the catheter in
place. Your bladder may be filled a second
time to ensure accurate results.

If you have been scheduled for a Video
Urodynamic study, we will fill your bladder
with x-ray contrast instead of water. The
contrast allows your doctor to use x-ray
images to see your bladder while filling,
straining, coughing, and passing urine.

After the Test
When the test is complete, the catheters and
pads are removed. If you were not taking
antibiotics before the test, you will be given
one antibiotic tablet after the test to prevent
infection. You should be able to return to
normal activity immediately following this
test. Some people may see blood in their
urine or have some mild discomfort while
urinating for a short time following this test,
this is not abnormal.
