Intravenous Pyelogram (IVP) is a special type of x-ray test that looks at the kidneys, ureters (tubes which transport urine from the kidneys to the bladder) and bladder. It is sometimes ordered for people who have known kidney stones or who are complaining of symptoms that are felt by their physicians to be suspicious for kidney stones (such as flank pain). Another common reason for ordering and performing this test is for the evaluation of hematuria (blood in the urine). A contrast or dye injection into a vein is required. This contrast is the same as that used for CT (CAT) scans. After the contrast is injected, the technologist will take a series of x-rays, which are reviewed and interpreted by a radiologist. The test usually takes approximately 30 minutes to complete.
