Intravenous Urogram (IVU)

An IVU is a test that shows us how your child's kidneys work. The test is done in the Radiology Department. During this test we will take x-ray pictures of your child's kidneys. The kidneys are a pair of bean-shaped organs that allow the body to collect urine and send it to the bladder.

Preparing your child for the IVU

Children 0-2 years

  • Give no solid foods on the day of the x-ray, until after the test is finished. Children may have juice or water on the morning of the test, up until 3 hours before it begins.

Children 2-15 years

  • The evening before the IVU give your child a Dulcolax suppository. Repeat this dose in the morning. If the second Dulcolax dose does not result in a very large bowel movement, give your child a saline or Fleet's enema. You can buy this at your local pharmacy.
  • On the day of the IVU, give no solid foods until after the test is finished. Children may have juice or water on the morning of the test, up until 3 hours before it begins.

What will happen on the day of the test?

  • The day of the IVU you will meet a radiologic technologist (RT). The RT helps the doctor, takes x-ray pictures, and answers your questions.
  • After your child has gone to the bathroom to empty his/her bladder, the RT will bring your child into an x-ray room. The room has a table with a square machine above it. This machine is like a large camera. It takes x-ray pictures that show how your child's kidneys are working. We will ask your child to lie very still, so that the x-ray pictures will be clear.
  • First, the technologist will take an x-ray of your child's abdomen. The RT or doctor will inject some contrast material into a vein in your child's arm through an IV. When the needle goes into your child's arm it stings for a moment. Contrast material is a liquid that goes from your child's vein into the kidneys. This allows the kidneys to be seen clearly on a x-ray. We will take some pictures of your child's kidneys as the contrast material goes from the kidneys to the bladder. The bladder is a balloon shaped organ where urine is stored in between the times your child goes to the bathroom.
  • You or your child may ask the technologist any questions about what is happening. We will develop all of the x-ray pictures before you leave to be sure they are what the doctor needs.

If you have any questions before this test, please call the Radiology Department at (603)-650-7446.
