Abstract
Increased use of cross-sectional imaging has led to an increase in the diagnosis of small renal masses （≤ 4cm）. Percutaneous renal cryoablation allows for a minimally invasive treatment option for select lesions and for the high risk surgical patient. Contemporary series suggest that renal cryoablation maintains good intermediate oncologic outcomes while minimizing patient morbidity. Over time, percutaneous renal cryoablation will play a central role in the management of patients with small renal masses, especially in elderly or comorbid patients.
