Cylinders Grained

Structure of the renal cylinders. Renal casts are formed from substances that have been filtered from the blood into the urine. In a healthy person, during urination, in addition to urine, fine sediment is excreted. It may contain bile (bile pigments) and other coloring substances - hemoglobin, myoglobin. After completing any stress or physical activity, the walls of the bladder are irritated, the person tenses, and the urine comes out more concentrated. At the same time, permeability

Greetings!

Today I want to tell you about such an unusual and interesting topic as Granular cylinders (syn.: Epithelial granular cells). These cells are a special type of cell found in the urine of some kidney diseases. Let's figure out what they are and what functions they perform in our body.

Granular casts are small round cells that consist of disintegrated epithelium of the renal tubules. On the surface of these cells there are droplets of fat or particles of protein, giving them a granular texture. Why can these cells be found in urine?

These cells are found in various kidney diseases such as necronephrosis and lipoid nephrosis. Necronephrosis is an inflammation of the kidneys that can lead to the destruction of the renal epithelium and the formation of these casts. Lipoid nephrosis is a rarer disease that causes fat droplets to form in the kidney tubules. These fat droplets precipitate and can clump together to form cylinders.

The functions of granular cylinders are still not fully understood. However, some of them are known. One of the functions is filtering fluid through the kidneys, as well as removing harmful substances from the body. In addition, the casts can perform a protective function, preventing damage to the kidney tissue.

But besides this, the presence of granular casts in the urine may indicate the development of other kidney diseases, such as diabetes, renal failure, nephrotic syndrome, etc. Therefore, if these cells are detected in a urine test, it is necessary to consult a doctor to diagnose and treat the underlying disease.

Thus, granular casts or epithelial granular cells are important diagnostic features for identifying kidney diseases. They can help doctors determine the cause of kidney problems and develop a treatment plan based on the diagnosis.

Conclusion

So, in the article we looked at the topic “Cylinders” Granular. We learned that these cells consist of disintegrating renal epithelium with the presence of fat droplets or protein particles on the surface. In some cases, these cells are found in the urine, which can be a diagnostic sign of kidney disease, but many other factors must also be considered. Thank you for your attention!
