In 31 patients with renal carcinoma referred for angiography, rapid sequence angiography was performed in 25. In 18 of the patients determination of renal blood flow and related parameters was made in conjunction with the angiography. Carcinomas with high and medium-high differentiation comprised Group I, while those with medium and poor differentiation constituted Group II. In both groups a positive correlation was demonstrated between the renal blood flow and the tumour area. In group I, positive correlation (t greater than 2) was demonstrated between the vascular volume and the tumour area, between the vascular resistance and the emptying time of the tumour arteries and the normal renal arteries. There was some degree of shunting of blood in all tumours. Comparison of the arterial emptying time of the tumour arteries with the parenchymal arteries does not allow of staging of renal carcinomas. The degree of shunting may be an indication of the degree of malignancy and poor differentiation.
在31例因需进行血管造影而就诊的肾癌患者中，25例接受了快速序列血管造影。其中18例患者在血管造影的同时测定了肾血流量及相关参数。高分化和中高分化癌归为I组，中分化和低分化癌归为II组。两组中肾血流量与肿瘤面积均呈正相关。在I组中，血管容积与肿瘤面积、血管阻力与肿瘤动脉及正常肾动脉的排空时间之间呈正相关（t大于2）。所有肿瘤均存在一定程度的血液分流。比较肿瘤动脉与实质动脉的动脉排空时间无法对肾癌进行分期。分流程度可能提示恶性程度和低分化程度。
