| granular cast | A relatively dark, dense urinary cast of coarsely or finely particulate cellular debris and other proteinaceous material, frequently seen in chronic renal disease but also in the recovery phase of acute renal failure. See: waxy cast. (05 Mar 2000) |
| waxy cast | A form of urinary cast consisting of homogeneous proteinaceous material that has a high refractive index, in contrast to the low refractive index of hyaline cast's; waxy cast's probably represent an advanced stage of the disintegrative process that results in coarsely and finely granular cast's, and are usually indicative of oliguria or anuria. (05 Mar 2000) |
