Urodynamics

Posted by Dr Jon-Paul Meyer on 17 September 2018
What are urodynamics?

Urodynamics are tests designed to assess bladder function and the bladder outlet. It helps in making a diagnosis about the cause of your bladder problems, and can help guide treatment decisions.

For example:
  • In men, it can sometimes be difficult to know if urine symptoms are caused by a bladder or a prostate problem.
  • In women with mixed incontinence (both stress and urgency incontinence), it is sometimes helpful to know which of the two is the main problem, and how much each problem contributes to overall symptoms.

How is the test performed?

The test is conducted on a day case basis in my clinic rooms, and only takes approximately 30-40 minutes. It is not painful. You will be asked to empty your bladder in private, into a special toilet, and the flow rate will be measured.

Soft, thin tubes will be inserted into your bladder and back passage to record pressure readings during the test. A small amount of local anaesthetic jelly is used to help insert the urine catheter.

Your bladder is filled with sterile water until you feel the need to urinate. You will be asked to cough at various stages during the test. At the end of the test, you will be asked to empty your bladder again, and the catheters will be removed.

After the test

Analysing the results takes some time, so it is usual for me to arrange a follow up appointment in my clinic rooms in order to discuss your results in detail with you. The test will help pinpoint the cause of your urine problems, and assist in deciding the right treatment for you.

What are the risks of this procedure?

All procedures have the potential for side effects. Although these complications are well recognised, the majority of patients do not have problems after a procedure.

Common risks:

  • Some mild discomfort when passing urine for a couple of days

Occasional:

  • Some mild bleeding in the urine

Rare risks:

  • Infection in the urine

Very rare

  • More serious infection (sepsis) requiring hospital admission and intravenous antibiotics

If you develop a fever, severe pain on passing urine, inability to pass urine or worsening bleeding, you should contact me immediately. If out of hours, please go to your nearest emergency department.
