How to Prepare for a Voiding Cystourethrogram
You should inform your doctor of any medications your child is taking and if he or she has any allergies, especially to contrast materials. Also let your doctor know about recent illnesses or other medical conditions.
Because a voiding cystourethrogram (VCUG) is an X-ray procedure, metal objects can affect the image, so avoid dressing your child in clothing with snaps or zippers. Replace metal diaper pins with adhesive tape. No other special preparation is required. An older child may be asked to wear a gown during the exam and to remove jewelry and eye glasses.
Sedation is rarely needed.
