Reasons for Test TOP
An IVP is done to look for:
- The cause of blood in urine
- Tumors
- Kidney stones or bladder stones
- Damage to the urinary tract from injury or infection
- Other problems that are causing kidney or bladder problems

Some factors that may increase the risk of complications include:
- Allergy to iodine or shellfish

Pregnant women should not have this test.
What to Expect TOP
Prior to test
Recent tests will be reviewed before the x-ray. Leading up to the test:
- A laxative and enema may be given the day before. It will empty your digestive system. Stool in the gut may make it harder to read the x-rays.
- Food and drink may need to be stopped after midnight the night before.
Description of the Test
An IV will be placed. The contrast material and any needed medicine will be passed through the IV. You will lie on a table for 30 to 60 minutes. X-rays will be taken at regular intervals. This will allow the doctor to see these body parts at work. It will better show where problems might be. You may be asked to hold your breath each time an x-ray is taken. You will also be asked to empty your bladder in a bathroom before the last x-ray.
After Test TOP
You can return to normal activity and diet.
