Voiding Cystourethrogram

Also known as: VCUG.

What is a voiding cystourethrogram?

A voiding cystourethrogram is an imaging test that checks the function of the bladder and urethra. The test involves performing an X-ray while a person is actively urinating.

What happens during the procedure?

A catheter is inserted into the patient’s urethra, and then a contrast dye is injected into the bladder. Various X-rays of the bladder are taken. Then the catheter is removed, and more X-rays are taken as the patient urinates and removes the contrast dye from the body.

Is any special preparation needed? 

No special preparation is needed for the test.

What are the risk factors?

Blood in the urine, an allergic reaction to the contrast dye or discomfort when urinating due to the catheter are all possible complications of this test.
