Identification and composition of types of granular urinary casts.
Granular urinary casts were analyzed by scanning electron microscopy and histochemistry. Three types were identified. They appear to have distinctly different origins and significance. Their clinical associations remain to be defined. One type can be misidentified by bright field microscopy. Bacterial casts also can be misidentified as granular casts unless the sediment is examined carefully.
