目的：探讨肾动脉栓塞在肾肿瘤手术治疗中的作用。方法：采用Seldinger技术对16例肾癌患者术前进行选择性肾动脉造影，碘油及明胶海绵栓塞，并对其术中病理改变及术后生存率作回顾性分析。结果：16例肾癌均能顺利切除，出血减少；肿瘤有不同程度的坏死，周围组织纤维化、粘连；1、3年生存率分别为68．8%、和56．3%。结论：肾动脉有助于晚期肾癌的手术切除，术前栓塞可提高肾肿瘤患者的生存率。
Objective: To investigate the role of renal artery embolization in the surgical treatment of renal tumors. Methods: Seldinger technique was used to perform selective renal artery angiography, lipiodol and gelatin sponge embolization in 16 patients with renal cell carcinoma. The pathological changes and postoperative survival rate were analyzed retrospectively. Results: All of the 16 cases of renal cell carcinoma were successfully resected and the hemorrhage was reduced. The tumors had varying degrees of necrosis and peripheral fibrosis and adhesions. The 1-year and 3-year survival rates were 68.8% and 56.3%, respectively. Conclusion: Renal artery is helpful for the surgical resection of advanced renal cell carcinoma. Preoperative embolization can improve the survival rate of patients with renal cell carcinoma.
