granular cast

granular cast
a cellular cast derived from a kidney tubule. In certain kidney diseases, notably acute glomerulonephritis, abnormal collections of renal tubular cells are shed from the kidney, often as a cast of the tubule. The casts can be observed on microscopic examination of the centrifuged deposit of a specimen of urine. Their presence in the urine indicates continued activity of the disease.
