肾癌是泌尿生殖系统常见恶性肿瘤,占成人恶性肿瘤的2%~3%,早期肾癌首选外科手术,疗效可靠[1],而中晚期肿瘤较大,手术切除困难,化疗、放疗缺乏敏感性,预后较差。肾动脉栓塞技术自1970年被应用以来,随着技术的进步及操作经验的积累,其不仅应用于血尿及肾癌转移灶的治疗,也应用于术前肾肿瘤栓塞,血管平滑肌脂肪瘤的治疗,血管畸形及肾移植后并发症的处理[2]。肾动脉栓塞术应用于治疗中晚期肾癌,以其微创
Renal cancer is a common malignant tumor of the genitourinary system, accounting for 2% to 3% of adult malignancies. The treatment of early renal cancer is the first choice of surgery, and the curative effect is reliable [1]. However, in the advanced stage, the tumors are large, the surgical resection is difficult, and the chemotherapy and radiotherapy are insensitive Sex, the prognosis is poor. Renal artery embolization technology has been applied since 1970, with the advancement of technology and accumulation of operational experience, it is not only used in the treatment of hematuria and renal cell carcinoma metastasis, also used in the treatment of preoperative renal tumor embolization, angiomyolipoma , Vascular malformations and complications after renal transplantation [2]. Renal artery embolization used in the treatment of advanced renal cell carcinoma, with its minimally invasive
