PURPOSE To evaluate the feasibility, safety, and effectiveness of minimally invasive percutaneous radiofrequency thermal ablation (RFA) in renal graft neoplasms. METHODS Three patients with transplanted kidney neoplasms were treated in our Centre with US-guided RFA; pre- and post-procedural serum creatinine levels were registered, as well as peri-procedural and long-term minor and major complications and deaths. Patients underwent laboratory and CT follow-up to the renal function and tumour response evaluation, respectively. RESULTS All patients were successfully treated, with a complete necrosis of the target lesion, a low rate of complications, and no significative alterations in post-procedural serum creatinine levels. Two patients underwent a 1-year follow-up, with stable complete response. CONCLUSIONS RFA of renal graft neoplasms is a feasible, safe, and effective treatment. This procedure should be considered as a viable therapeutic option, granting good results, and preserving renal function. This article is protected by copyright. All rights reserved.
