What is a Urodynamics?
Urodynamics is a specialized test that will tell your doctor how your bladder functions.
This test is done at our North Island Urology office by our nurse, Jane. You may or may not see the doctor at the time of your urodynamics appointment. If you do not have an appointment with one of the urologists, a follow-up will be arranged for you to discuss the results.
When you first arrive at the office, you will meet with Jane to review the test. This investigation has several small tests which may be performed.
You do not need to do anything special to prepare for this test, but we do ask that you arrive with a comfortably full bladder. Your doctor will tell you whether you are to continue your bladder medications or not.
Urine Flow Test
- The first test you will complete is a Uroflow test.
- You will void in a special toilet that tells us your urine volume and how strong your stream is.
- After that test, Jane will place a small catheter into your bladder to see how well you emptied your bladder.
Cystometry
- A small catheter will be inserted into your urethra.
- Another small catheter will be placed in your rectum.
- These catheters measure the pressure on your bladder and your abdomen.
- Sterile fluid will then slowly be infused into your bladder. Jane will be asking you questions, such as when you feel like your bladder is full, and if you have any sensations of urgency or need to urinate.
- Once your bladder is full, you will be asked to empty your bladder. This is ideally done with the small catheters still inside your bladder.
- Once the procedure is complete, all catheters will be removed.
