What is Urodynamics?

Urodynamics is a specialised test to look at how your bladder works. It is used to find out why women might be losing urine (incontinence) or why they are getting symptoms from their bladder. Future treatment will depend on these results.

How is Urodynamics performed?

The first thing you do during the test is to sit on a toilet that has a computer attached to it. The doctor will go outside while the computer measures how quickly the urine is passed.

You then lie down on an x-ray table and we pass a very thin tube like a catheter into the bladder. This is the most uncomfortable part of the test but it only takes 2 or 3 seconds. The bladder is then filled using a saline solution and the catheter has pressure sensors on it, which measures the pressure as your bladder fills up. We then stand the table up and take some images using 3 D ultrasound or occasionally moving X-Ray pictures..

Do I need to do anything to prepare for Urodynamics?

  • Wear a short top and pants if possible.
  • When you come for Urodynamics we would like you to have a moderately full bladder.
  • If you are menstruating at the time of the appointment please call the surgery and we will make alternative arrangements.

How long does the test take?

The whole test takes between 25-40 minutes, but you will need to allow about 1 hour for the appointment.

The test is usually done by me and my nurse or my Research Fellow. Occasionally a training Physiotherapist will attend to observe the test. If you feel uncomfortable with this please advise my secretary.

Are there any risks involved?

1-3% of women will develop a urinary tract infection after the test. Fully disposable catheters and sterile water are used to minimize the risk of infection. Increasing fluid intake in the first few hours after the test will minimize the risk of infection. If we consider you high risk for infection we will give you an antibiotic.


The fees are calculated to cover the cost of the equipment and disposables. Please ask my secretary what the fees are when you make your appointment. Fees are paid at the time of consultation.
