description: "A type of acellular urinary cast located within the distal tubules of the kidney and that is composed only of Tamm-Horsfall glycoprotein. Correspondingly, these casts have a low refractive index. Hyaline casts may display a spectrum of morphologies, which includes fluffy, compact, convoluted or wrinkled casts. Hyaline casts have a smooth texture and usually have parallel sides with clear margins and blunted ends."
