Computed Tomography Intravenous Pyelogram (CT/IVP, IVP (Intravenous Pyelography)

Risks

There is always a slight chance of damage to cells or tissue from radiation, including the low levels of radiation used for this test. However, the chance of damage from the X-rays is usually very low compared with the benefits of the test.

There is slight risk of having an allergic reaction to the contrast material. The reaction can be mild (itching, rash) or severe (difficulty breathing or sudden shock). Death resulting from an allergic reaction is very rare. Most reactions can be controlled with medicine. Be sure to tell your doctor if you have asthma or allergies of any kind, such as hay fever, iodine allergy, bee stings, or food allergies.

People with certain conditions (such as diabetes, multiple myeloma, chronic kidney disease, sickle cell disease, or pheochromocytoma) have increased chances of having sudden kidney failure from IVP. Older adults and people taking medicines that affect the kidney may also have increased chances for problems after an IVP.
