A Rare Complication Of Microwave Ablation For Renal Cell Carcinoma; Nephrocolic Fistula.

INTRODUCTION Nephrocolic fistula is a pathological connection between the kidney and colon. Percutaneous tumour ablation therapy is a rare cause of iatrogenic nephrocolic fistula in the literature. CASE PRESENTATION Interventional radiologists should be careful, especially in patients with repeated ablation. Granulation of tissue may lead to unexpected results secondary to tissue fragility and impedance changes. CONCLUSION In addition, we should keep in mind that there is decreasing hydro dissection benefit in cases with the previous ablation. As far as we know, this is the first case report of an iatrogenic ephrocolic fistula after microwave ablation for recurrence renal cell carcinoma.
