It also is important to determine whether CT urography is the appropriate imaging modality. Depending on the clinical scenario, multiple phases may not be required, and therefore the radiation dose can be reduced .

3D of the collecting system can be performed, as needed or requested. However, in the common sense, to exploit all the potential of this technique, CT urography is understood as a combination of renal CT plus CT of the contrast-enhanced upper urinary tract. Therefore, in most centers, a three-phase CT urographic protocol, consisting of unenhanced, nephrographic, and excretory phases, is performed [ 1 , 3 , 7 ].

studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol). CT urography (CTU or CT-IVU) has now largely replaced traditional IVU in imaging the genitourinary tract.
