Fatty casts are seen in people who have lipids in urine. This is most often a complication of nephrotic syndrome. Granular casts are a sign of many types of kidney diseases.
What does the presence of casts in urine mean?
What does the presence of casts in urine suggest? If an actors is seen in the urine, kidney illness or in- volvement exists; the presence of casts shows kidney (kidney) illness instead of reduced urinary system system illness. All casts have a matrix of Tamm- Horsfall mucoprotein to which various other pro- teins or aspects might be included.

Hyaline casts can be identified in both healthy individuals and those with certain pathological conditions. In most cases, they indicate a decreased or sluggish urine flow, which can be caused by dehydration from strenuous exercise, diuretic medications, or severe vomiting, or by decreased blood flow to the kidneys.

Types Of Casts Found In Urine And Their Clinical Significance. Urine casts are cylindrical, cigar-shaped structures produced by the kidney and present in the urine in certain disease conditions. All casts are composed of a mucoprotein known as Tamm-Horsfall protein which is secreted by the distal loop of Henle, ...
Where are casts formed in the urinary tract?
Urinary casts are formed only in the distal convoluted tubule (DCT) or the collecting duct. The proximal convoluted tubule (PCT) and loop of Henle are not locations for cast formation. Casts are the result of solidification of material (protein) in the lumen of the kidney tubules.
What is a hyaline cast?
Hyaline Casts. Hyaline casts are the most common type of casts which are composed of solidified Tamm-Horsfall mucoprotein. They have smooth texture and a refractive index very close to that of the surrounding fluid. Generally, hyaline casts have parallel sides with clear margins and blunted ends.
How many hyaline casts are there in urine?
Hyaline cast in urine for healthy people ranges between 0 to 5 per power field. If you have just performed an exercise routine, there could be an increase in the number of hyaline casts. There are other types of the cast that could be detected in the urine and each is associated with different types of kidney-related diseases.
How to check for kidney infection?
To check the existence of kidney infection, a urine sample is checked for the presence of blood, pus, or bacteria. A urine culture might be needed depending on the discretion of the attending physician as per the result of the first requested lab test.
What is granular cast?
Granular Casts. 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.
How are fatty casts formed?
Fatty Casts. Fatty casts are formed by the breakdown of lipid-rich epithelial cells. These contain lipid droplets within the protein matrix of the cast and are identified by the presence of refractile lipid droplets. They are usually seen in the conditions like tubular degeneration, nephrotic syndrome, hypothyroidism etc.
Where do casts form in the kidney?
They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy.
Why are casts larger than hyaline casts?
In addition, due to urinary stasis and its formation in dilated and diseased ducts, these casts are significantly larger than hyaline casts. They are cylindrical. They have a higher refractive index. They are more rigid and show sharp edges, fractures and broken ends.
Why are waxy molds bigger than hyaline casts?
In addition, due to urinary stasis and its formation in dilated and diseased ducts , these casts are significantly larger than hyaline casts.

What are the filtering units in the kidneys?
They’re composed of millions of filtering units called nephrons. Each nephron is composed of a glomerulus (a ball-shaped network of blood vessels involved in the formation of urine) and kidney tubules (a series of tubules that reabsorb and modify urine composition according to the body’s necessities).

How to treat kidney disease?
Treatment for kidney disease means managing the underlying cause of the disease, including blood pressure, blood sugar, and cholesterol levels. Your doctor may prescribe a blood pressure medication to slow the progression of the disease or preserve kidney function, even if you don’t have high blood pressure. Healthy dietary and lifestyle changes are also important.
