Abstract
Percutaneous ablative techniques under imaging guidance have become a frequently used treatment method in the therapy of primary T1a or secondary renal tumours, especially in patients who were burdened with comorbidities and are not surgical candidates. Radiofrequency ablation with single or multiple electrodes has been the primary ablative technique used and the mainstay of percutaneous therapy for a long time but with the evolution of technologies, microwave ablation and cryoablation have emerged as possibly more effective methods of treatment. After the initial experience with CT-guided radiofrequency ablation for renal carcinoma treatment in 6 patients, we started using microwave ablation with the following 6 patients. Our results showed microwave ablation to have bett er results in achieving complete tumour ablation, while requiring shorter hospitalization time and better patient satisfaction. There have not been any major complications, while minor complications were more frequent with microwave ablation. Due to shorter procedure time patients treated with microwave ablation, we no longer used general anaesthesia but only local anaesthetic with conscious sedation.
