(UroToday.com) Increasing utilization of cross-sectional imaging in primary care and emergency departments had led to an increase in the incidental diagnosis of renal masses. While the majority of these are renal cell carcinoma, a number of other entities are on the differential diagnosis including renal oncocytomas. Long-term outcomes of patients who undergo surgery for renal oncocytomas are sparse and, for the most part, non-contemporaneous. In a podium presentation at the American Urologic Association Virtual Annual Meeting, Dr. Matvey Tsivian and colleagues presented results of a single center study of patients surgically treated for renal oncocytoma at the Mayo Clinic.
