Renocolic fistula as a complication of radiofrequency in the treatment of renal cell carcinoma.

Method: Beyond postoperative suspicion, retrograde pyelogram was performed, the images of which are displayed, and demonstrated the fistula.
Results: Treatment has been definitive nephrectomy after failed attempt to seal the fistula with suture and TachoSil.
Conclusions: Although radiofrequency ablation can be a valid technique for treating small renal tumors in patients with high morbidity, it is not without significant complications as described in this case, despite the precautions taken.
