We present the case of a 54 year old man with a synchronous mass on each kidney with different renal cell carcinoma (RCC) subtypes and a normal renal function. He categorically refused to undergo radical nephrectomy and open partial nephrectomies. He underwent a laparoscopic right partial nephrectomy and then percutaneous CTguided bilateral cryoablation. A second percutaneous CT-guided course of cryoablation on the right mass was performed at 6 months post cryoablation for recurrence. Both chest and abdomen CT-Scan at 60 months follow up did not reveal any local recurrence or distant metastasis.

Although cryoablation is a feasible treatment option for RCC, the authors do not recommend it as a first line therapy in an otherwise healthy patient with normal renal function.
