Voiding Cystourethrogram


What do I need to know about a voiding cystourethrogram?

A voiding cystourethrogram (VCUG) is an x-ray of your bladder and urethra while you urinate.

How do I prepare for the VCUG?

Your healthcare provider will talk to you about how to prepare for the VCUG. There may be some discomfort as the catheter is inserted.

What will happen during the VCUG?

You will lie down on a table and an x-ray will be taken before the procedure. A catheter will be lubricated and gently inserted through your urethra into your bladder. Contrast dye will be put through the catheter into your bladder so it shows up clearly on the monitor. X-rays will be taken at different angles while your bladder is full of contrast dye. The catheter will be removed so you can urinate. More x-rays will be taken while you urinate and once your bladder is completely empty.

What are the risks of a VCUG?

You may bleed more than expected or get an infection. You may have some discomfort when you urinate after the procedure. Your bladder may be injured during the procedure.
