Definition

An x-ray image of the kidneys, ureters, and bladder, and prostate in men, that is taken after a contrast dye is injected into a vein. As the dye travels through the bloodstream, it collects in these organs, turning them bright white. This allows the health care provider to see blockages or other urinary tract problems on the x-ray pictures. An IVP may be used to help diagnose certain urinary tract conditions, such as kidney or bladder stones, kidney cysts, urinary tract tumors, and an enlarged prostate. Also called intravenous pyelogram, intravenous urogram, and IVU.
