title: [A Case of Recurrent Renal Cancer in the Autografted Kidney, Treated with Percutaneous Cryoablation].
abstract: We report a case of recurrent renal cancer in the autografted kidney, treated with percutaneous cryoablation. A 59-year-old man who had bilateral renal tumors underwent radical left nephrectomy, ex vivo right partial nephrectomy and auto-transplantation at the right ileal fossa in our hospital 11 years ago. Histopathological examination showed clear cell renal cell carcinoma in bilateral kidneys (pT1bN0M0). He had been followed at another hospital without tumor recurrence for 11 years. In 2014, an enhanced CT scan revealed a renal tumor with a diameter of two centimeters in the autografted kidney, which was thought to be a recurrence of the initial renal cancer. He was referred to our hospital for further evaluation and treatment. He underwent percutaneous renal tumor biopsy, which confirmed renal cancer recurrence, followed by percutaneous cryoablation. Three months after cryoablation, an enhanced CT showed that the enhancement lesion in the autografted kidney had disappeared, and these findings were confirmed pathologically by absence of malignancy by a subsequent needle biopsy. The level of serum creatinine (sCr) was 1.16 md/dl immediately before cryoablation and 1.46 mg/dl at three months after cryoablation. Nine months after cryoablation, the patient had no reccurence and renal function was stable (sCr 1.43 mg/dl).
