A 62-year-old man with renal cell carcinoma in the solitary kidney after right nephrectomy underwent CT-guided radiofrequency ablation. The tumor, which was located in the dorsal part of the lower aspect of the kidney, was exophytic and measured 2 cm in diameter. A 17-gauge, internally cooled radiofrequency needle electrode was placed percutaneously into the center of the lesion. Dynamic CT 6 days after the first ablation showed band-like residual lesion along the intact renal parenchyma. A second ablation was performed for the residual lesion. CT both 1 and 3 months after the second procedure demonstrated complete ablation with the normal renal parenchyma maintained.
一名62岁男性，右肾切除术后单肾患肾细胞癌，接受了CT引导下的射频消融术。肿瘤位于肾脏下极背侧，呈外生性，直径2厘米。一根17号内部冷却的射频针电极经皮插入病变中心。首次消融6天后的动态CT显示沿完整肾实质有带状残留病变。对残留病变进行了第二次消融。第二次手术后1个月和3个月的CT均显示消融完全，肾实质保持正常。
