Abstract
IntroductionColorenal fistula is a rare phenomenon and may complicate percutaneous cryoablation of renal cell carcinoma. Treatment remains controversial.Case presentationA 62-year-old Caucasian man presented with pneumaturia and left flank pain six weeks following ultrasound-guided percutaneous cryoablation of two recurrent lesions in the left kidney 14 years after partial left nephrectomy for a left renal cell carcinoma. A computed tomography scan eight weeks after cryoablation revealed a cryoablated mass with adjacent stranding and adherent descending colon as well as bubbles of gas in the area of stranding, the left collecting system, and the bladder. These features were consistent with a colorenal fistula at the site of previous ablation. Successful resolution of the fistula, both clinical and radiological, was achieved following a complete conservative non-interventional out-patient approach. No ureteric stent or surgical intervention was employed.ConclusionsIn the absence of severe symptoms or sepsis, complete conservative management of a colorenal fistula complicating percutaneous cryoablation of renal tumors should be considered prior to interventional stenting or resectional surgery.

Summary
Colorenal fistula complicating percutaneous cryoablation of renal cell carcinoma has been reported in the literature on two previous occasions [1,2]. We present a patient with a colorenal fistula complicating cryoablation of renal tumors who had his fistula successfully treated with a complete conservative approach. Having considered possible ureteric stenting [1] or resectional surgery [2], we decided to treat our patient with a completely conservative non-interventional outpatient approach. He was given a two-week course of. All symptoms of pneumaturia and pain resolved within one month, and a follow-up CT scan confirmed complete resolution of the colorenal fistula (Figure 2). Our patient was followed up for 18 months after resolution of the fistula
