Renal radiofrequency ablation: Technique and results

Laparoscopic or percutaneous radiofrequency ablation has become a viable treatment option for small renal tumors. Although long-term results are not yet available, intermediate results show promise for the treatment of select renal lesions. Here, we describe the basics of radiofrequency ablation technology, outline techniques used for both percutaneous and laparoscopic treatment routes, and provide a brief review of clinical results to date.
