title: Choice between US and CT in the radiological approach to the renal masses.
abstract: The diagnostic reliability of ultrasound (US) and computed tomography (CT) has been analyzed in 114 patients with renal masses (RM) detected by urography and consequently submitted to both exams. A flowchart is suggested in order to avoid useless examinations; accordingly, the US examination is always justified in the study of RM as opposed to the CT examination (requested only in 50% of RM) and angiography (requested only in 35% of RM).
