telescoped urinary cast
telescoped urinary cast, mixed
A moulded proteinaceous cast that may be found in urinary sediment, which contains all types of cells and material known to spill over into the urine in renal disease–e.g., erythrocytes, leukocytes, tubular epithelial cells, hyaline and granular material, fat and lipids.
Telescoped urinary casts are typical of lupus nephropathy, but can be seen in other collagen vascular diseases and renal disease–e.g., acute and chronic glomerulonephritis, nephrotic syndrome, transplant rejection, subacute bacterial endocarditis, hyperviscosity syndrome, malignant hypertension, eclampsia, heavy metal poisoning, multiple myeloma, amyloidosis, and sickle cell disease.
