Intravenous Pyelogram (IVP) Test
An intravenous pyelogram (IVP) is an x-ray test that uses contrast dye to take pictures of your urinary tract, including the kidneys, bladder, and ureters. It helps find blockages or other problems.
What this test measures
An IVP uses x-rays and contrast dye to show the organs of the urinary tract: kidneys, bladder, ureters, and in males, the prostate. The dye makes these organs visible on x-ray images.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Frequently asked questions
What is an IVP?
An IVP (intravenous pyelogram) is an x-ray test that uses contrast dye to take pictures of your urinary tract, including kidneys, bladder, and ureters.
Why might I need an IVP?
According to MedlinePlus, an IVP may be used to find the cause of symptoms involving the urinary tract or prostate, such as kidney stones, tumors, or enlarged prostate.
How is an IVP done?
Contrast dye is injected into a vein using an IV line. The dye travels to your kidneys and collects in the urinary tract, making it show up bright white on x-rays.
Is an IVP still commonly used?
No, IVP is not commonly used anymore. Providers usually order CT scans instead, as they provide more information. However, IVP may be useful in certain situations.
What do abnormal IVP results mean?
Abnormal results may show that a urinary tract organ is not the right size or shape, or there may be a tumor, stone, cyst, scar, or blockage. In males, the prostate may be larger than normal.
