Intravenous Urography

Intravenous Urography used to examine the urinary tract, a contrast medium containing iodine is injected intravenously (into a vein, usually in the arm). The iodine improves the contrast on the x-ray image. Some people are allergic to iodine and must be pre-medicated. Prior to the procedure, all patients should be sure to fill out the contrast screening form and to notify the radiographer of any prior reaction. Intravenous Urography (IVU) and Pyelography (IVP) are different names for x-ray examination of the kidneys, ureters, and bladder. This test yields information about the function of the kidneys, the presence of stones in the urinary tract, and the passage of urine from the kidneys to ureters and bladder.

IVP is commonly done to identify diseases of the urinary tract, such as kidney stones, tumours, or infection. It is also used to look for problems with the structure of the urinary tract that were present from birth (congenital). The test takes approximately one hour. Some patients may experience a brief sensation of warmth, nausea, or a metallic taste in the mouth after the contrast medium injection. Other patients may experience itching, hives, or other effects. The radiographer or nurse closely monitors all patients for any adverse drug events.
