IVP (intravenous pyelogram)

An intravenous pyelogram (IVP), also known as intravenous urography (IVU), is a medical imaging test that uses X-rays to visualize the urinary system. It involves injecting a contrast dye into the bloodstream, which is then excreted by the kidneys and outlines the urinary tract. IVP helps doctors assess the structure and function of the kidneys, ureters, and bladder, aiding in the diagnosis of various conditions.
