Computed tomography (CT) urography use CT images after intravenous contrast material to obtain images of the urinary tract. CT urography (CTU) is used as primary imaging techniques the evaluation of hematuria, which is blood in the urine, to follow patients with prior history of cancers of the urinary collecting system and to identify abnormalities in patients with recurrent urinary tract infections.
Urography images are used to evaluate issues or detect abnormalities in portions of the urinary tract, including the kidneys, bladder and ureters, including:

- Kidney or bladder stones
- Cancers of the urinary tract
In addition to imaging the urinary tract, CT urography can provide valuable information about other abdominal and pelvic structures and diseases that may affect them.
