An intravenous pyelogram (IVP) is an X-ray exam of your urinary tract (kidneys, ureters, and bladder). This test can help find stones or other problems with your urinary tract.
Follow all instructions on what to eat and drink before the test.
If instructed, take a laxative the night before your IVP.
For your safety, your health care provider needs to know about any of the following:
Allergies, especially to iodinated intravenous (IV) contrast (a substance that improves X-ray images). You can still have an IVP if you are allergic to the contrast substance, but you will need to take a medication beforehand.
Previous kidney or bladder problems.
Diabetes medication you take.
Any previous surgery.
If you are or may be pregnant.
Risks associated with IVP include:
Reaction to the contrast substance, which may be mild (itching, hives, nausea) or severe (difficulty breathing, swelling of the throat, drop in blood pressure)
Worsening of kidney damage
Your health care provider will give you an intravenous (IV) injection of contrast.
You’ll be asked to move from side to side and then hold still as X-rays are taken.
Your health care provider may apply pressure to your belly to help get the best images.
You may be asked to empty your bladder before the final X-ray.
Your doctor will discuss the test results with you during a follow-up visit or over the phone.
