The objective of this study was to analyze and assess the experience with radiofrequency ablation of small renal masses using a contrast-enhanced, ultrasound-guided percutaneous approach for patients who are not suitable for surgical resection and/or who refused surveillance or observation. From January 2007 to August 2015, 164 treatments were performed on a total of 148 patients. We present the patients’ clinical-radiological characteristics, oncological and functional results in the short and medium term. The overall technical success rate was 97.5%, with a successful outcome in 1 session in 100% of the lesions ≤3cm and 92% in lesions measuring 3–5cm. The mean tumor diameter in the patients for whom the treatment was ultimately successful was 2.7cm, while the mean diameter of these in the unsuccessful operations was 3.9cm (p
