Granular casts are composed of plasma protein aggregates and cellular remnants. Granular casts appear as cylinders of coarse, or fine, highly refractive particles.
Broad casts or "renal failure' casts are formed in the collecting ducts as the result of urinary stasis and are two to six times the size of other types of casts. Any type of cast can be a broad cast. Broad casts are typically seen in patients with advanced renal failure.
Hyaline casts, the type most commonly seen in urine sediment, have a refractive index similar to the urine in which they are suspended. For this reason, hyaline casts will appear almost invisible under brightfield microscopy, but are easily of seen by phase-contrast microscopy.
Match the following descriptions of casts with their appropriate name:
1. Casts with highly refractive particles
2. "Renal failure" cast
3. Low refractive index
