Urodynamics Study (UDS)

What is UDS?

A UDS is a diagnostic procedure that is performed in the office during which a very small catheter is placed through the urinary channel into the bladder for purposes of filling the bladder with fluid and monitoring pressures. A second catheter may also be placed just inside the anal opening to help measure the pressures that occur around the bladder during normal functioning.

What is the purpose of UDS?

A UDS is performed primarily to help diagnose disorders of the lower urinary tract. These include urinary leakage, symptoms of obstruction of the urinary tract, as well as symptoms that may occur in individuals with neurologic conditions. With the information gathered from urodynamics study, your physician will be better able to diagnose and thus treat a wide variety of urologic abnormalities and diseases.

What are common symptoms following UDS?

Most patients report minimal symptoms following the procedure. The catheters that are utilized are sterile catheters that are very small and placed in a medically clean manner. The test is brief in duration and most patients report only minimal discomfort from placement of the catheters. After the procedure, some patients report a small amount of discomfort or burning when they void for the first 1-2 cycles of the bladder. A small amount of blood may also be noticed in between urination or when wiping following urination.

When should I call my physician?

Anytime a patient runs a temperature greater than 101 degrees or has persistent burning with urination beyond 1-2 days, they should contact their physician’s office for further tests and possible treatment.
