An intravenous pyelogram (IVP) is a type of x-ray examination specifically designed to study the kidneys, bladder, and ureters (the tubes which carry urine from the kidneys to the bladder).
After iodine-based contrast dye is injected into a vein, a series of images are taken at timed intervals. The kidneys are responsible for removing contrast dye from the blood and collecting it in urine.
Abnormalities in the appearance of the kidneys or ureters, abnormalities in the distribution of contrast within a kidney, unequal amounts of dye in each kidney, or abnormalities in the collecting systems can be identified. These all suggest particular diseases and conditions.
