Radiofrequency ablation of malignant renal tumor: report of three cases

Resumen

Three cases of radiofrequency ablation of small malignant renal tumor performed at Clinica Internacional, in Lima, Peru, were presented. Two female patients aged 69 and 37; and a male patient (with only one kidney) of 65 years old, are reported. They presented incidental diagnosis of small single kidney tumor (less than 3 cm) by imaging studies, showing radiological signs of malignancy in all three cases. The patients did not receive surgical treatment for different reasons. A renal biopsy was performed for anatomopathological confirmation (AP) and, immediately after, the radiofrequency thermal ablation (RF) of such renal tumors with excellent results after the procedure and in the subsequent follow-up.
