超选择性肾动脉栓塞化疗术在肾癌治疗中作用的评价

目的：探讨肾癌根治性切除前肾动脉栓塞化疗术对肾癌的疗效。方法：将73例肾癌患者分为两组：治疗组30例,肾癌根治术前行超选择性肾动脉栓塞术;对照组43例,单纯行肾癌根治术。结果：治疗组手术时发现瘤体明显缩小,表面静脉萎缩,易于剥离,平均手术时间200min,输血量330ml;而对照组平均手术时间250min,输血600ml。术后1、3、5年的生存率治疗组为96.7%、90.0％、83.3％,对照组为100％、91.4%、81.3%,差异无显著性意义。结论：肾癌根治性切除术前行肾动脉栓塞化疗术可缩短手术时间,减少术中失血量,但不能明显提高患者的生存率。

The value of superselective embolization of renal artery in the treatment of renal carcinoma

Purpose:To study the therapeutic effectiveness of superselective embolization of renal artery in the treatment of renal carcinoma before radical nephrectomy. Methods:From 1994 to 2000, 73 cases of renal cell carcinoma were randomized into two groups. The experimental group (30 cases) were treated by superselective embolization of renal artery before radical nephrectomy, and the control group (43 cases) were treated with radical nephrectomy alone. Results:There were significant differences between these two groups in surgical time and transfusion blood volume, and there were no significant difference in 1 year, 3 year and 5 year survival rate between these two groups. Conclusions:Superselective embolization of renal artery before radical nephrectomy would reduce operation time and transfusion blood volume, but would not improve the patient survival.
