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 fistulain in the literature.

CASE PRESENTATION

Interventional radiologist should be careful especially in patients with repeated ablation. Granulation 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 hydrodissection benefit in cases with 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.
