What is Urodynamics?
A urodynamic study is a series of tests that evaluate how your bladder and urethra work. The test will attempt to re-create your urinary symptoms so that your doctor can determine the best treatment for you.
What will happen on the day of the study?
The Nurse will review the test procedure with you and answer any questions that you may have.
What is done during the Urodynamics test?
There are a few steps to the test. For the first part, you will be asked to empty your bladder, in private, using a special commode.
After you have emptied your bladder into the special commode, small catheters will be placed into your bladder and into your vagina (or rectum). These special catheters measure the pressure in your bladder.
Your bladder will be filled using the catheter in your bladder and you will be asked to cough and strain during different points in filling.
Once your bladder is full, you will be asked to empty your bladder in the special commode with the catheter in place. Most patients can void easily with the catheters in place, as the catheters are so small.
The entire test is done as discretely as possible to help maintain your privacy. The nurses who perform the urodynamics are experienced and understand the embarrassment that incontinence episodes can cause.
How long will the procedure take?
The procedure lasts about an hour.
Will the test be painful?
For the most part, the test done is relatively painless. You may feel some irritation when the catheter is introduced into your urethra and bladder. After the test, you may have some mile burning on urination. This should disappear after several hours. Drinking water will help dilute your urine and make the burning disappear after several hours. Drinking water will help dilute your urine and make the burning sensation decrease.
What do I need to do to prepare for the test?
- Please try to arrive with a comfortably full bladder. Do not use the bathroom for 2-3 hours prior to your test.
- There is no need to restrict your diet or fast for the urodynamic study. You should follow your normal diet and take any of your routine medications. It is helpful to drink liquids before coming to the appointment so that your bladder is comfortably full, as mentioned above.
- If you arrive and are unable to wait to empty your bladder, please let the receptionist or nurse know before you use the rest room.
