Bladder Function (Urodynamic) Tests

Your consultant or nurse will fill your bladder with fluid using a small, soft catheter (tube), which will be put into your bladder. Another catheter will be inserted into your rectum. After connecting the catheters to a computer, your consultant or nurse will measure how well your bladder responds. They'll also measure how well your bladder works when you pass urine.

The test will take about 30 minutes and you can usually go home straight after it. You may also have an X-ray screening to look at the way your bladder expands and contracts.

You'll be asked to stop taking any bladder medication in preparation for your test. Your consultant will tell you when you should do this. You can eat and drink as usual before having a urodynamic test. And you'll normally be asked to come to your appointment with a comfortably full bladder.

You should drink plenty of fluids for the first 24 to 48 hours after your test to help reduce the risk of urine infection. You may be given antibiotics in preparation for this. A follow-up appointment will be made with your urologist to discuss the results of your test.
