A Systematized Approach to the Differential Diagnosis of Renal Masses

Abstract

By using a flow chart, the nature of a given entity may be evaluated by selecting the most appropriate studies in sequence. The authors present such a schema for the differential diagnosis of renal masses, based on evaluation of approximately 200 renal lesions. In this way, duplication of studies is avoided, hospitalization costs are minimized, complications are lessened, radiation exposure is reduced, and conservative treatment of benign lesions is encouraged. Life-threatening renal masses may be separated from those of lesser consequence with an accuracy approaching 100%.
