21 Μαρ 2023 · Granular casts are similar to hyaline casts, but they’re associated with more cell breakdown and are more likely to result from chronic kidney disease. Waxy casts. Waxy casts are advanced...
Granular casts are a type of cellular or proteinaceous structure that can be found in urine when conducting a microscopic examination. They are sometimes referred to as “granular casts” or “coarse granular casts.”
7 Μαΐ 2024 · Granular casts are cylindrical structures that can be found in urine samples under microscopic examination. These casts are formed from protein aggregates and other cellular debris that accumulate in the kidney tubules and are then excreted in the urine.
14 Δεκ 2022 · Granular casts result either from the degeneration of cellular casts, or direct aggregation of plasma proteins or immunoglobulin light chains. They have a textured appearance which ranges from fine to coarse in character. Their appearance is generally more cigar-shaped and of a higher refractive index than hyaline casts.
13 Μαΐ 2024 · Granular casts: These casts are composed of debris from kidney cells and can be seen in conditions such as acute tubular necrosis. Waxy casts : These are large, dark, and brittle casts that may indicate advanced kidney disease.
21 Σεπ 2018 · All casts are composed of a backbone of uromodulin. As a result, all casts begin to form in the loop of Henle and further develop in the distal tubular lumens. Granular casts, which may be fine, course, or mixed (hyaline-granular cast), generally reflect tubular injury.
Urinalysis and urine sediment exam is most helpful with fresh urine whether voided or collected from clamped foley catheter tubing and collected from valve with syringe (within 30-60 minutes). Foley catheters can introduce hematuria due to insertion and urethra/bladder trauma.
