Preparing for a urodynamics test

Urodynamics is a test of the lower urinary tract. It is done to find the cause of symptoms such as:

• Incontinence
• Urgency
• Trouble peeing

The test uses a small catheter in the bladder and anus. It measures pressure when you fill and empty your bladder.

• No anesthesia is used.
• You cannot pass or fail the test.
• The test is simple and has few side effects. Some patients may take antibiotics to prevent infection.
• The test may take 30 to 45 minutes.

Cystoscopy is a test that uses a camera to look in the bladder. It can be done at the same visit.

Before your urodynamics test:

• Eat the way you normally do.
• Take all routine medications.
• If you take bladder medication, check with your doctor. They will tell you if you should stop taking it before the test.
• Arrive for the test with a full bladder.
