A Rare Case of Nephrocolic Fistula Resulting from Radio Frequency Ablation (RFA) of Renal Cell Carcinoma

Nephrocolic fistula is a rare, abnormal fistulous connection between the urinary system (kidney/ureters) and colon. Different benign and malignant etiologies are implicated in the formation of a nephrocolic fistula. Even though conservative treatment options have been tried recently (especially for benign etiologies), surgical resection has been the treatment of choice and should be pursued if conservative management fails. We report the first case of a nephrocolic fistula after a radiofrequency ablation of a renal cell carcinoma, which required surgical resection after conservative management failed.
