Answer

Upper tract imaging is necessary for the hematuria workup. The imaging modality chosen should be able to visualize the kidneys and the urothelium.

American Urological Association Best Practice Policy recommends CT scanning of the abdomen and pelvis with contrast, with preinfusion and postinfusion phases. [78] This evaluation is ideally performed with CT urography, using multidetector CT, or it can be performed with a single-detector CT-scan study followed by an excretory radiographic study of the kidneys, ureters, and bladder (KUB) to obtain images similar to those produced with intravenous pyelography.

Conduct retrograde pyelography in patients in whom contrast CT scanning cannot be performed because of azotemia or a severe allergy to intravenous contrast.
