Abstract

About three thousand resin vascular casts of human renal glomeruli were examined with a scanning electron microscope, and two extremely rare glomeruli with quadruple or quintuple efferent arterioles were found. Each of these multiple efferent arterioles arose independently from the glomerular capillary tuft supplied by a single afferent arteriole. In addition, 34 glomeruli possessed double or triple efferent arterioles and two showed double afferent arterioles. In one of the former cases, one of the double efferent arterioles had a heterotopic origin near the urinary pole of the glomerulus. No glomerulus with triple or more afferent arterioles was noted.

摘要

用扫描电子显微镜检查了约3000个人类肾小体的树脂血管铸型，发现了两个极为罕见的具有四重或五重出球小动脉的肾小体。这些多条出球小动脉中的每一条都独立地起源于由单个入球小动脉供应的肾小球毛细血管丛。此外，34个肾小体具有双条或三条出球小动脉，两个肾小体显示有双条入球小动脉。在前者的一个病例中，双条出球小动脉之一在肾小球尿极附近有异位起源。未发现具有三条或更多条入球小动脉的肾小体。
