Intravenous Pyelogram (IVP)
Computed Tomography Intravenous Pyelogram (CT/IVP, IVP (Intravenous Pyelography)
What To Think About
- A preliminary X-ray picture (KUB) of your abdomen will be taken before the intravenous pyelogram (IVP). This picture is reviewed by the radiologist before the next part of the test begins. An IVP test may not be done if these pictures show a problem.
- Other tests that may be used instead of an intravenous pyelogram (IVP) include computerized tomography (CT scan), ultrasound, digital subtraction angiography, and, occasionally, MRI. For more information, see the medical tests CT Scan of the Body, Abdominal Ultrasound, Angiogram, and Magnetic Resonance Imaging (MRI) of the Abdomen.
- For people who have known kidney problems, diabetes, or who are dehydrated, steps may be taken to prevent kidney damage. Less contrast material may be used and additional fluids may be given before, during, and after the test.
- If you have had kidney problems in the past, blood tests for creatinine and blood urea nitrogen may be done before the test to make sure that your kidneys are working properly. For more information, see the medical tests Creatinine and Blood Urea Nitrogen.
- Another test that may be done to look at the urinary tract is retrograde ureteropyelogram. Retrograde ureteropyelogram is done when IVP results do not help identify a problem or when IVP cannot be done because of poor kidney function or an allergy to the iodine contrast material.
