Why is the urine epithelial cell count high?

Everyone will experience some diseases in their life. Of course, we don’t want to get sick, but if we don’t pay attention to our lifestyle habits and don’t have a regular schedule, then some diseases will occur. In order to avoid the occurrence of diseases, it is recommended that you exercise more and pay attention to a healthy diet. Some people have many problems due to bad habits, such as high urinary epithelial cell count. So what is the reason for the high urinary epithelial cell count? This is something we don’t come across often, so we need to understand it.

1. Red blood cells. Red blood cells may occasionally be seen in normal human urine, with no more than 3 per high-power field of view after centrifugation. If there are a large number of red blood cells in the urine, it may be caused by kidney bleeding, urinary tract bleeding, renal congestion, etc. Vigorous exercise and blood circulation disorders can also lead to increased glomerular permeability, resulting in the appearance of protein and red blood cells in the urine.

2. White blood cells. There are a small number of white blood cells in normal human urine, with no more than 5 per high-power field of view in centrifuged urine. When abnormal, the urine contains a large number of white blood cells, indicating that there are suppurative lesions in the urinary tract, such as pyelonephritis, cystitis and urethritis.

3. Small round epithelial cells. In normal urine routine examination, a few small round epithelial cells with fatty degeneration can sometimes be found. In case of glomerulonephritis, the number of epithelial cells in the urine increases. If there is a lesion in the renal tubules, many small round epithelial cells may appear.

Squamous epithelial cells generally have little clinical significance. Transitional epithelial cells are divided into surface, middle and bottom transitional epithelial cells due to their different sources. Among them, an increase in middle transitional epithelial cells is common in pyelonephritis, etc. Small round epithelial cells come from the kidneys. They are rare in normal urine but may appear in large numbers when renal tubular lesions occur. They are of certain value in the localization and diagnosis of renal parenchymal diseases. When there is chronic renal congestion, renal infarction and hemoglobin deposition, round cells containing brown granules (containing hemosiderin) in the cytoplasm can be seen.

The cells examined in a routine urine test include red blood cells, white blood cells, and epithelial cells. A small amount of epithelial cells can be seen in normal urine, and epithelial cells can be seen in every high-power field of view in centrifuged urine under a microscope, which is still normal. Epithelial cells are divided into flat, transitional, and small round epithelial cells.

From the above content, we understand the problem of why the urine epithelial cell count is high. Generally speaking, there is no big problem. It is mainly related to the human kidneys. If there is a problem with the kidneys, this situation will occur. Therefore, we should pay attention to eating more foods that are good for the kidneys, avoid eating greasy foods, and improve our dietary structure.
