What is a voiding cystourethrogram?
A voiding cystourethrogram is a test which uses X-rays to take pictures of the urinary system. It shows how well the bladder and its connecting tubes (the urethra and the ureters) are working.

Before the test
Before you come to the hospital, explain to your child what will happen. For young children, use simple words and explain only right before the test.

During the test
Your child will lie on an X-ray table. A small tube, or catheter, will be placed into the bladder through the urinary meatus, the opening where urine comes out. A special liquid called X-ray contrast material will be used to fill the bladder through the catheter. When your child's bladder is full, your child will urinate into a urinal or special container while on a table. While the child is urinating, the X-ray technologist or doctor (radiologist) will take X-ray pictures.

Your child will need to lie still while the catheter is being placed and while the X-ray pictures are taken. It is often difficult for young children to hold still for this. If your child is unable to lie still, he/she may be restrained with a special belt. Often parents may stay in the X-ray room during the test, but you may be asked to wait outside in the waiting room. The test usually lasts about 30 minutes.

It is expected that during the procedure your child may experience some discomfort. Please tell the doctor, nurse or technologist if significant or prolonged pain occurs so it can be evaluated and you can be referred to your child's primary doctor.

After the test
The technologist will tell you that you may leave when all the X-ray pictures are taken. Your child may return to normal daily activities.

After having the urinary catheter placed for the test, your child's urine may be pink-colored the first time he/she urinates. This is caused by a small amount of blood in the urine. If this happens more than once or your child has difficulty urinating, call your child's doctor.

Results of the test will be sent to your child's doctor who will contact you about the results.
