A 56-year-old female with past medical history of thrombotic microangiopathy presented to her physician with nonspecific abdominal pain. A magnetic resonance imaging scan was obtained, which revealed a 3.1 cm mass arising from medial lower pole of the left kidney that was subsequently shown to be renal cell carcinoma by percutaneous biopsy. Because of her history of thrombotic microangiopathy and other comorbidities, she was deemed a nonsurgical candidate and was therefore referred to interventional radiology for thermal ablation. Computed tomography (CT)-guided microwave ablation was performed with the combined use of pyeloperfusion and hydrodissection for maximal ureteral protection. Follow-up unenhanced CT scan obtained one month after ablation showed a normal collecting system without evidence of hydronephrosis or urinoma.
一名有血栓性微血管病既往病史的56岁女性因非特异性腹痛就诊于她的医生。进行了磁共振成像扫描，结果显示左肾下极内侧有一个3.1厘米的肿块，经皮活检后证实为肾细胞癌。由于她有血栓性微血管病病史和其他合并症，她被认为不适合手术，因此被转介至介入放射科进行热消融治疗。采用肾盂灌注和水分离联合技术进行计算机断层扫描（CT）引导下的微波消融，以最大程度地保护输尿管。消融术后1个月进行的随访非增强CT扫描显示集合系统正常，没有肾盂积水或尿瘤的迹象。
