Radiofrequency ablation of renal tumors.

Radiofrequency ablation (RFA) of renal tumors is a relatively new treatment modality in the armamentarium of urologic surgeons. One of the challenges of this technique is attaining a zone of tissue destruction sufficient enough to kill the targeted tumor. Technologic innovations have aided in this effort. The clinical experience with RFA of renal tumors suggests that small, exophytic tumors may be more readily ablated. Although there is much optimism with regard to this technology, further study is required to better define the oncologic efficacy and refine proper patient selection.
