Initial experiences comparing CT-guided radiofrequency and microwave ablation int he treatment of renal carcinoma

Percutaneous ablative techniques under imaging guidance have become a frequently used treatment method in thetherapy of primary T1a or secondary renal tumours, especially in patients who were burdened with comorbidities and arenot surgical candidates. Radiofrequency ablation with single or multiple electrodes has been the primary ablative techniqueused and the mainstay of percutaneous therapy for a long time but with the evolution of technologies, microwave ablationand cryoablation have emerged as possibly more eff ective methods of treatment. After the initial experience with CT-guidedradiofrequency ablation for renal carcinoma treatment in 6 patients, we started using microwave ablation with the following6 patients. Our results showed microwave ablation to have bett er results in achieving complete tumour ablation, while requiring shorter hospitalization time and bett er patient satisfaction. There have not been any major complications, whileminor complications were more frequent with microwave ablation. Due to shorter procedure time patients treated withmicrowave ablation, we no longer used general anaesthesia but only local anaesthetic with conscious sedation.
