  • Tumors
  • Kidney stones or bladder stones
  • Damage to the urinary tract from injury or infection

  • Allergy to the iodine contrast dye
  • Blood disorders
  • Poor kidney function
  • Certain medications

What to Expect

Prior to test

Leading up to the test:
  • You will need to have kidney function tests.
  • The day before the test, you may be asked to use laxatives and enemas to empty your digestive system. This is because stool in the intestines may make it harder to read the x-ray pictures.
  • Do not eat or drink after midnight.

Description of the Test

An IV will be inserted. This will provide the contrast dye and any medication that you will need. For the next 30-60 minutes, you will lie on a table while x-rays are taken at regular intervals. You may be asked to hold your breath each time an x-ray is taken. The dye will highlight your urinary system on the x-ray. This will allow your doctor to see these body parts at work and detect problems. Before the last x-ray, you will empty your bladder in a bathroom.

After Test

You will be able to resume your normal activities and diet.

How Long Will It Take?

About 60-90 minutes

Will It Hurt?

No, but you may feel a sensation of warmth or heat as the contrast dye travels through your body.

Results

It may take a few days to receive your test results. Your doctor will discuss the results with you, as well as any treatment.
