Lisanti et al [7] found that in 442 patients <40 years of age and without risk factors, no patient had a malignancy-related hematuria finding at CTU. MRU MRU is not useful as a first-line imaging modality for the evaluation of microhematuria in patients with no known risk factors and with an identified benign cause of microhematuria. There is no relevant literature regarding the use of MRU for the initial evaluation of microhematuria. Hematuria MRI Abdomen and Pelvis For the purposes of this document, we make a distinction between MRU and MRI abdomen and pelvis without and with IV contrast. MRI abdomen and pelvis without and with IV contrast is defined as any protocol not specifically tailored for evaluation of the upper and lower urinary tracts, without both the precontrast and excretory phases, and without heavily T2-weighted images of the urinary tract. There is no relevant literature regarding the use of MRI for the initial evaluation of microhematuria. Radiography Abdomen and Pelvis Conventional radiographs of the abdomen and pelvis (KUB) are not used as a first-line imaging modality for the evaluation of hematuria. There is no relevant literature regarding the use of radiography for the initial evaluation of microhematuria. Radiography Intravenous Urography IV urography (IVU) is no longer used as a first-line imaging modality for the evaluation of hematuria. There is no relevant literature regarding the use of IVU for the initial evaluation of microhematuria. US Kidneys and Bladder Retroperitoneal Ultrasound (US) is not useful as a first-line imaging modality for the evaluation of microhematuria with no known risk factors and with an identified benign cause of microhematuria. Variant 2: Microhematuria. Patients with risk factors, without any of the following: history of recent vigorous exercise, or presence of infection or viral illness, or present or recent menstruation, or renal parenchymal disease. Initial imaging.
