Video Urodynamics is the study of pressure and flow in the lower urinary tract.

The purpose of this procedure is to assess what happens in your urinary tract when it fills and empties. During the test, is a PVes (vesical pressure) catheter is inserted into the bladder through the urethra, and a PAbd (abdominal pressure) catheter is inserted into the rectum. While you’re lying down, your bladder will be filled with contrast medium through the bladder catheter. X-rays are also taken to assess how your bladder and urethra are functioning. The purpose of this procedure is to find out how the bladder acts when it fills and empties.

It is performed by the urologist under local anesthetic, with one or two Registered Nurse(s) present and an X-Ray Technologist. The procedure and review take approximately  60-90 minutes in the Radiology Department of UBC Hospital.
