Pyelography is the technique of taking photographs of the kidneys, ureter, and bladder. Your Ureter carries urine from a kidney to the bladder. These photographs are done using X-rays. To perform a pyelography, a patient must be injected with an opaque solution or a radiopaque dye. A radiopaque dye becomes visible in both an X-ray and fluoroscopy. The procedure is often called an intravenous pyelogram. It is not as scary as it sounds. In Fact, an intravenous pyelogram also called an IVP, may allow your doctor to treat your condition with medication, and avoid surgery.

1. When Does a Doctor Order a Pyelogram?

Most often a doctor will order a pyelogram if there is suspected obstruction to the flow of urine. Usually, this means the doctor suspects a blockage due to a kidney stone. Patients with problems related to the kidneys might also need to undergo this test as it provides information about the functioning of the kidneys. If your doctor suspects you have any problem with your kidney, or urinary tract this is most often the first test ordered. Your doctor may even order a CT scan done at the same time, as a CT scan also uses contrast dye.
