Morphology of erythrocyte casts in urine sediment: microscopic signs of renal hematuria in glomerulonephritis and other kidney lesions.
Microscopy of urine sediment. Erythrocyte casts. Erythrocyte casts are pinkish-yellow and reddish-brown, formed in the tubules during renal hematuria (hemorrhage into the renal parenchyma in renal infarction, embolism, acute diffuse glomerulonephritis), consisting of a mass of erythrocytes and located against their background.
