What does it mean to have hyaline casts in urine?
Also to know is, are hyaline casts normal in urine?
Casts: Casts are formed in the tubules of they kidney when the tubules secrete a protein called Tamm-Horsfall protein. These casts are known as hyaline casts and can be present in normal adults on the order of 0-5 per LPF. Strenuous exercise can cause more hyaline casts to be present.
One may also ask, are hyaline casts dangerous? Hyaline casts are the type most commonly seen in the urine sediment. Pathologically, hyaline casts may be seen with congestive heart failure, and may be seen together with other types of casts in a variety of renal diseases.
Subsequently, one may also ask, what does it mean to have casts in urine?
Casts are the result of solidification of material (protein) in the lumen of the kidney tubules, more specifically in the nephron. If a cast is seen in the urine, kidney disease or in- volvement exists; the presence of casts indicates kidney (renal) disease rather than lower urinary tract disease.
What are hyaline casts?
Hyaline Casts. Casts are clusters of urinary sediment elements (red blood cells, white blood cells, fat bodies, etc.) wrapped in a protein matrix. Cast formation necessarily occurs in the kidney tubules, and the the contents of the casts indicate the nature of the abnormalities occurring in the kidney itself.
