Step-by-step explanation:
The radiographic diagnostic test used to outline the structures of the kidney, ureters, and bladder is known as Intravenous pyelogram (IVP). An IVP involves injecting a contrast dye into a vein, which then travels to the kidneys, ureters, and bladder. X-ray images are taken as the dye moves through these structures, providing a detailed view of their anatomy.
