Using a single cool-tip needle with CT guidance, we performed RFA of 15 renal tumors (seven RCCs and one renal metastasis from leiomyosarcoma) in 11 patients (six men and five women; age range, 23-83 years; mean age, 55.8 years), including seven solitary kidney. Tumor size ranged from 7 to 35mm in the largest diameter (mean diameter, 23.1mm). The follow-up period ranged from 1 to 13 months after RFA (mean period, 4.8 months). We were able to completely ablate except a 35 mm RCC with extension into the renal sinus fat. We could perform RFA without severe complications. It seems that RFA of renal tumor is a promising technique.
