Abstract
With the shift towards minimally invasive treatment, percutaneous thermal ablation, including radiofrequency ablation and cryoablation, can be a promising alternative for small renal tumor treatment. Although there are few reports of the long-term oncological outcomes after thermal ablation of renal tumors, high local tumor control rates and cancer-specific survival rates have been reported. Careful patient selection, adequate understanding of ablation modalities, and outstanding ablation techniques are required for interventional radiologists to maximize the clinical outcomes of renal thermal ablation. Moreover, a close collaboration with urologists is important. In this article, the indications, techniques, safety, and oncological outcomes of thermal ablation for renal tumors are reviewed.
