[Radio-frequency ablation of T1a renal cell carcinoma].
We report the efficacy of radio-frequency ablation (RFA) for T1a renal cell carcinoma (RCC). RFA was performed under epidural or local anesthesia by ultrasound or computed tomography (CT) guidance in seven patients with Tla RCC, who were at significant operative or anesthetic risk for invasive surgery. At a median follow-up of 17.5 months, 6 (86%) of the seven patients showed no tumor enhancement in follow-up CT scans or magnetic resonance images. Temporary macroscopic hematuria was observed in one case. RFA is an effective and safe minimally invasive therapeutic option for selected patients with RCC who have reason to avoid invasive surgery under general anesthesia.
