To elucidate abnormalities in renal morphology related to perfusion preservation, we examined kidneys perfused for 60 hr with a scanning electron microscope. In addition to tubular necrosis and fused glomerular visceral epithelial foot processes, we identified changes in the glomerular endothelial and arterial endothelial surfaces. The glomerular endothelium revealed fenestrae that were smaller and more irregular than normal, as well as abnormal bulbous projections. The arterial endothelium displayed striking degenerative changes. These abnormalities may account for the altered glomerular function and intravascular coagulation that occur in some kidneys preserved by lengthy perfusion.
