Japanese Urological Association reported that 3,648 patients of renal cell carcinoma were diagnosed in 2007 from 340 institutions and 70 years old or more accounted for 35.5% of pa- tients and 8.3% were more than 80 years old. If the elderly patients are frail and have severe comorbidity, surveillance might be taken for small renal cancer. However, relatively large tu- mor or rapid tumor growth rate lead to disease progression. Because percutaneous ablation to renal cell carcinoma is less invasive treatment than surgery and is superior in quality of life maintenance, it will be suitable treatment for small renal carcinoma of elderly patients. We showed results of the radiofrequency ablation of renal cell carcinoma of elderly patients 80 years or older. Among 17 patients, four patients were dead of other causes and the death due to renal carcinoma was absent. Only one patient had local tumor progression and needed re- ablation. Renal function preservation after treatment was good.
