Article Abstract

Safety and delayed intervention rates of active surveillance for small renal masses in an elderly population

Authors: Brian T. Kadow, Marc C. Smaldone


The incidence of incidentally detected renal masses thought to represent renal cell carcinoma (RCC) has increased with widespread utilization of cross-sectional imaging, with many of these lesions being considered small renal masses (SRMs), ≤4 cm in maximal diameter (1,2). These lesions were historically treated surgically, with either radical nephrectomy or nephron-sparing surgery (NSS), or with percutaneous ablation.
