Urodynamic testing is often used to try and find out what is causing bladder problems. It is the study of the bladder’s ability to hold and empty urine. It measures the way the bladder relaxes to fill and then contracts to empty. The evaluation is assisted with a computerised study.
Allow a total appointment time of one and a half hours for test and review by the doctor.
Before the Procedure
- No special preparation is required for the procedure. You may eat and drink as normal.
- Keep taking your usual medications. You will not be required to stop taking Aspirin, Warfarin or anti-inflammatory medications, unless specifically instructed by your doctor.
- Please do not pass urine prior to the test.
- Please do not feel embarrassed or upset if you have difficulty controlling your bladder during the test, as the test is designed to find the cause of your problem.
During the Procedure
- You will be escorted to theatre and asked to change.
- You may be asked to empty your bladder into a special flow meter, similar to a toilet.
- You will be asked to lie on the examination table, the nurse will explain the procedure and be in attendance throughout the procedure.
- The area will be cleaned with an antiseptic solution.
- Two small catheters are placed into your bladder. The first catheter is used to fill your bladder with fluid and the second catheter measures the pressure inside your bladder.
- A small catheter is also placed into your rectum. This allows the computer to calculate the true bladder pressure. Your bladder will be filled with sterile water.
- The nurse will ask you to describe the differing sensations you feel during the procedure and the computer will record these.
- Once your bladder is full you will be asked to pass the water into the flow meter, which can measure the bladder pressure and flow of urine. The computer can then calculate whether your bladder has a normal emptying capacity.
- A bladder ultrasound scan is performed at the completion of the urodynamics study.
After The Procedure
- The tubes will be removed and you will be able to get dressed.
- The results are printed and discussed with you by your doctor.
- A sick certificate and follow-up appointment will be arranged if necessary
- You should be able to resume normal activities the next day.
- A courtesy call may be made as part of our quality control programme.
