Urinary casts are small, cylinder-shaped, tube-shaped particles that can be detected by a microscopic analysis of urine. Casts are the only kidney-specific components discovered in the urine sediment. It is believed that Tamm-Horsfall mucoprotein (uromodulin) released by renal tubular epithelial cells forms the fundamental matrix of all casts. Any components present in the tube filtrate, … Read more
