A urodynamic study is a series of tests that evaluate how your bladder and urethra work. The test will attempt to recreate your urinary symptoms so that your doctor can determine the best treatment for you.
The nurse will review the test procedure with you and answer any questions that you may have.
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.
The procedure lasts about an hour.
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 mild burning on urination. This should disappear after several hours. Drinking water will help dilute your urine and make the burning sensation decrease.
