This study was undertaken to evaluate the feasibility, safety, and therapeutic effects of percutaneous renal cryoablation under local anesthesia with conscious sedation for patients who have unresectable stage 1 (T1NoMo) cell carcinoma (RCC) in high surgical risk. Eighteen were not candidates surgery underwent primary cryosurgery guided by gray-scale ultrasound. Contrast-enhanced ultrasonography (CEUS) contrast-enhanced computed tomography (CT) performed treatment at completion. The mean follow-up period 26.8 months (range, 12–56 months). All tumors biopsied before cryosurgery. Seventeen remained free enhancement during period. No major complications associated procedures found though two instances subcapsular hematomas, one retroperitoneal errhysis nausea, seen after cryoablation. One patient had a recurrence tumor received additional Local control rate 100 % T1NoMo including case Percutaneous can be recommended as feasible, safe, promising therapy tumor, especially those RCC, low risk complications.
