Voiding Cystourethrogram
(Bladder Study)


A voiding cystourethrogram is the study of your bladder using a contrast agent that shows how it empties and if there is any reflux in the ureters to the kidneys.

There is no preparation for this study.  A catheter will be inserted in your bladder before the examination by the radiologist or a nurse. 

Because contrast material is used during the VCUG, please advise the technologist if you have an allergy to contrast, medication, foods and have any history have hay fever or asthma.

  • You will be asked to change into a hospital gown. 
  • You will be asked to lie on the X-ray table on your back and a scout film will be taken. 
  • The catheter is then inserted into your bladder.  The radiologist will introduce contrast material into the bladder through the catheter and will watch your bladder fill utilizing X-ray equipment.  A series of images will be taken of your urinary system until the bladder is at its fullest. 
  • At this time you will be asked to void (release fluid in your bladder) into a special container, or for children, a padded area will be used.  While you are voiding, the radiologist will take a series of pictures of your bladder as it empties.  The examination usually takes about 30 minutes.

Important note:
If you are of child-bearing age and think there is any possibility of pregnancy it is important that you inform the physician ordering these X-rays and tell the technologist taking your X-rays.  If you have any known allergies to contrast, iodine, or foods please inform your physician BEFORE proceeding with any of the instructions that follow.
