Urodynamic test (1922)

Key points below

What is a Urodynamic test?

The Urodynamic test is done on the bladder, urethra and urinary muscles (sphincters). The test shows how well the muscles and nerves in the bladder work with the nerves in the brain and spine. The muscles and nerves must work together while the bladder is filling, storing and emptying urine (pee).

Why does my child need the test?

How is the test done?

The test takes about 90 minutes.

Will the test hurt?

As the catheter is put in it may feel funny but it should not hurt. You may want to bring something that helps your child feel safe and calm.  This could be a special toy or blanket. Please bring distraction items like an iPad, movies, or other items your child enjoys. Pack snacks and a drink as your child may eat and drink during the study. You will be able to stay with your child during the test.

What about the test results?

The results are reviewed by a provider with special training. This doctor is called a urologist. The provider will explain the results to you. This test will show any bladder problems your child may have.
