A computerized tomography (CT) urogram is an imaging exam used to evaluate your urinary tract, including your kidneys, your bladder and the tubes (ureters) that carry urine from your kidneys to your bladder.
CT urography uses X-rays to generate multiple images of a slice of the area in your body being studied, including bones, soft tissues and blood vessels. These images are then sent to a computer and quickly reconstructed into very detailed, 2-D images.
During a CT urogram, an X-ray dye (iodine contrast solution) is injected into a vein in your hand or arm. The dye flows into your kidneys, ureters and bladder, outlining each of these structures. X-ray pictures are taken at specific times during the exam, so your doctor can clearly see your urinary tract and assess how well it’s working or look for any abnormalities.
