Urodynamic is a study of the urinary bladder. It involves a group of tests that measure the function and pressure in the bladder as well as the flow of urine through the urethra (tube through which urine is passed out of the body).
When you arrive in the department you will be greeted by one of the nurses who will be looking after you throughout the procedure, she will ask you to provide a sample of urine for her to test to ensure you do not have an infection. If you do have an infection the procedure will be postponed and you may require some antibiotics.
For the procedure you will be asked to change into a gown. Once you are feeling comfortable on the couch, two fine catheters will be inserted; one into the bladder through the urethra and the other into your rectum (back passage). Your bladder will then be filled slowly with sterile water. While your bladder is filling a number of recordings will be made, we will ask you how your bladder feels and you will be asked to cough and perform some movements while lying down and standing to check for leaks.
When your bladder is full we will ask you to cough to try to make the bladder leak. We will then ask you to pass water into a special commode. We will leave the room while you are passing water and return when you are finished. The test is now finished and when you feel comfortable you can leave.
