(IVP; Excretory Urography; Intravenous Urography [IVU])
An intravenous pyelogram (IVP) is a test that evaluates problems in the urinary tract. It is done with contrast dye and x-rays
The Male Urinary System
Reasons for Test
An IVP is done to identify:
- The cause of blood in urine
- Kidney stones
Complications are rare, but no procedure is completely free of risk. If you are planning to have an IVP, your doctor will review a list of possible complications, which may include:
- Allergic reaction to the contrast material
- Kidney failure
Some factors that may increase the risk of complications include:
- Allergy to contrast dye (eg, iodine)
- Blood disorders
- Poor kidney function
- Taking certain medicines
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 possibly enemas to clean out your gut. 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 line will be inserted. This will provide the contrast dye and any medicine 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.
You will be able to resume your normal activities and diet. Be sure to follow your doctor's instructions.
How Long Will It Take?
About 60-90 minutes
Will It Hurt?
No. You may feel a sensation of warmth or heat as the contrast dye travels through your body.
It may take a few days to receive your test results. Your doctor will discuss the results with you, as well as any treatment.
