Ablation Therapies in Small Renal Masses

Abstract

Small renal masses are defined as renal neoplasms with the largest diameter less than 4 cm and the incidence of renal malignancies is increased with the widespread use of cross-sectional imaging methods. One of the options for disease management in small renal masses is ablation therapy. Ablation therapies include options such as radiofrequency ablation, cryoablation and irreversible electroporation. In this review, outcomes and comparisons of ablation therapies used in small renal masses are discussed together with current approaches and studies.
