In the past, intravenous urography (IVU) was the most commonly used diagnostic method for the evaluation of patients with hematuria in the past. In current practice, however, it is increasingly being replaced by computed tomography (CT) urography. [13]

Filling defects in the upper urinary tract can be demonstrated in 50-75% of patients. Other common causes of filling defects (eg, nonopaque stones, blood clots, papillary necrosis with sloughing, and fungus balls) should be ruled out. In 13-31% of cases, the affected kidney may not be adequately visualizable.
