The role of radiologic imaging and biopsy in renal tumor ablation

Purpose  

The rate of unintentionally discovered renal masses has been increasing along with a parallel increased incidence of renal cell carcinoma both in men and women. Ablation therapy has emerged as an alternative for the treatment of these small renal tumors. Several techniques have been developed for renal tumor ablation with cryoablation (CA) and radiofrequency ablation (RFA) being among the most widely used and studied. The purpose of this article is to review the role of imaging and renal mass biopsy in renal tumor ablation with focus on CA and RFA.
