Reasons for Test
An IVP is done to identify:

  • The cause of blood in urine
  • Tumors
  • Kidney stones or bladder stones
  • Damage to the urinary tract from injury or infection
  • Other problems keeping the kidney or bladder from functioning normally
Possible Complications
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

Some factors that may increase the risk of complications include:

  • Allergy to the iodine contrast dye
  • Blood disorders
  • Poor kidney function
  • Certain medications
Pregnant women should not have this test.

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.

Call Your Doctor
Call your doctor if you have any concerns after the procedure. Call if you have any of the following symptoms:

  • Nausea and/or vomiting
  • Itching or skin rash
  • Shortness of breath
If you think you have an emergency, call for medical help right away.
