The study of microarterial pattern of human kidney by Butylbuterate and Microfil Silicone Rubber compound cast technique has been carried out. The arcuate arteries and their major intrarenal branches were seen running in the tissue tunnels (the area devoid of glomeruli and capillary plexus) not observed by any other worker in the field. The aglomerular giant arterioles arising from arcuate and interlobar arteries were observed. Afferent arteriole feeds glomerulus and afferent breaks up into capillary plexus. Aglomerular afferents have also been observed. Glomeruli were distributed right underneath the renal capsule. Vasa-recta, from arcuate artery and capillary plexus at the corticomedullary junction were running almost a straight course deep into the medulla unlike the observations of Castelli and Huelke (1968) who noticed the tortuous course. However the present study revealed that the vasa-recta become highly tortuous when they terminate by anastomosing with each other at the apex of the renal papilla. When a major artery pierces through the vasa-recta bundle near corticomedullary junction, the bundle divides into 2 and each half arches round that vessel to continue as a single bundle.

采用丁酸丁酯和微丝硅橡胶复合铸型技术对人肾的微动脉模式进行了研究。可见弓形动脉及其主要的肾内分支走行于组织隧道（无肾小球和毛细血管丛的区域），该区域此前该领域的其他研究者均未观察到。观察到由弓形动脉和叶间动脉发出的无肾小球的巨大小动脉。入球小动脉为肾小球供血，入球小动脉分支形成毛细血管丛。也观察到了无肾小球的入球小动脉。肾小球分布于肾被膜正下方。与Castelli和Huelke（1968年）观察到的走行迂曲不同，来自弓形动脉和皮质髓质交界处毛细血管丛的直小血管几乎呈直线深入髓质。然而，本研究显示，直小血管在肾乳头顶端相互吻合终止时变得高度迂曲。当一条主要动脉在皮质髓质交界处附近穿入直小血管束时，该束分成两部分，每一部分围绕该血管形成弓形，然后继续作为一个单一的束。
