Medically reviewed by Last updated on Jul 7, 2024.

What do I need to know about a VCUG (voiding cystourethrogram)?

A 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.

What will happen during the VCUG?

You will lie down on a table and an x-ray will be taken before the procedure. Your healthcare provider will lubricate and gently insert a catheter into your bladder. Contrast liquid 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 liquid. 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 or get an infection. You may have some discomfort when you urinate after the procedure. Your bladder may be injured during the procedure.
