What is the reason for high white blood cell index in sediment

Many times when you go to the hospital for medical treatment, you need to undergo a routine urine test. The health status of the human body can be seen from the human urine. Experts say that white blood cells can fight bacteria and viruses and belong to the category of the immune system. If the number of white blood cells in urine increases, it may be caused by infection of the body. We must pay attention to it and not take it lightly. The following article will introduce to you the reasons why the sediment white blood cell index is high.

What is urine sediment

Urine sediment is the shaped components in urine. It is the sediment formed after the original urine is centrifuged. It is a combination of the quality and quantity of urine formed components. Including various pathological components such as cells, tubules, crystals, bacteria, sperm, etc.

Examination indicators of urine sediment usually include detection of red blood cells, white blood cells, renal tubular epithelial cells, and casts.

What is the reason for high white blood cell index in sediment

Normal people's urine contains a small amount of white blood cells. Generally speaking, the number of white blood cells in microscopic examination of sedimented urine will be less than 1 per high-power field of view. When the number of white blood cells in microscopic examination of clean midstream urine sediment is greater than 5/high-power field of view, leukocyturia can be diagnosed.

Leukocyturias can be seen in urinary system diseases, prostate diseases, seminal vesicle diseases, and diseases of tissues and organs adjacent to the urinary system, such as gynecological inflammation. The causes may include infection, conjugation, stones, foreign bodies, tumors, glomerulonephritis, tubulointerstitial diseases, etc. Therefore, clinically, leukocyturia should be analyzed in depth and should not be simply considered as a urinary tract infection. For patients with unexplained leukocyturinia, quantitative bacterial culture should be performed. If the culture is negative for multiple times, attention should be paid to whether it is urinary tract tuberculosis or fungal infection. The diagnosis is as follows:

1. The presence of white blood cell casts in the urine can help diagnose pyelonephritis.

2. In the absence of culture results for acute urinary tract infection, a preliminary diagnosis can be made based on pyuria.

3. If the patient has frequent and urgent urination, the urine stays in the bladder for a short time, and the urine bacterial quantitative culture will be negative. At this time, pyuria can assist in diagnosis.

4. If the bacterial culture of a urinary tract infection is negative after treatment with antibiotics, but pyuria still exists within a few days, the pyuria is positive at this time, indicating that it is still a urinary tract infection.

Note:

When there is an excessive amount of white blood cells in urine routine, we must pay attention to actively go to the hospital for examination and treatment. In terms of diet in daily life, we also need to pay attention to drinking more water, not eating spicy food, and keeping a light diet.

Urine sediment examination notes:

After the patient's urine is collected, it should be examined under a microscope promptly. Otherwise, if it is left for too long, hemolysis may occur if the urine is hypotonic; dehydration may occur and the shape of red blood cells may change if the urine is hypertonic; and alkaline urine may cause the collapse of blood cell components and casts, affecting the accuracy of the test.
