What's the matter with high white blood cell count in urine routine

When something is wrong with the body, we need to go to the hospital for many tests to diagnose the disease. Among them, urine routine test is particularly widely used in clinical practice. The high and low values ​​of white blood cells in urine routine test items are of great significance for detecting whether the kidney function is healthy. Usually, doctors can judge whether the human body is healthy based on the results of this test combined with the patient's various symptoms. It is an important basis for judging kidney function and urinary system diseases. A high white blood cell count in urine routine may indicate that the body is being invaded by certain pathogens. Common diseases include nephritis, cystitis, urethritis, and renal tuberculosis. The specific disease still needs a doctor's diagnosis. Let’s take a closer look at what is going on when the white blood cell count in urine routine is high.

After centrifugation, the white blood cell content of normal urine is generally: 0-2/hp for men and 0-5/hp for women (hp is the high-power field of view of the microscope, i.e. 40x). The quantitative urine white blood cell measurement by the machine is represented by “+” and “-”, “+” means positive, “-” means negative, and negative means normal. So what happens when the white blood cell count in urine is high?

If the white blood cells in the urine are >5/hp, it means there is purulent inflammation of the urethra, such as nephritis, cystitis or urethritis, renal tuberculosis, etc.

It should be mentioned that due to allergic reactions caused by taking medicines, there will be an increase in white blood cells in the urine; when women's leucorrhea is mixed with urine, there will also be an increase in white blood cells.

Therefore, when the white blood cell test in a routine urine test is positive, there is no need to panic. You should first check whether you have other symptoms, such as edema; whether your urination is normal, etc. If the urine routine test results show only one + white blood cell, there is no need to worry. Just wait for the diagnosis to be confirmed and receive timely treatment.

Patients with kidney disease will have symptoms of hematuria, and the cause of hematuria is closely related to the high level of white blood cells in urine.

1. There are many reasons for high white blood cell count in urine routine, but the most common one is kidney disease. Therefore, when a routine urine test finds that the white blood cell count in the urine is high, it is necessary to check whether it is a kidney disease so as to determine the treatment method in time and control the disease to avoid more serious consequences.

The most common kidney diseases include pyelonephritis, pyonephrosis, renal abscess, kidney stones with infection, renal tuberculosis, and tubulointerstitial lesions.

2. Ureteral and bladder diseases are also one of the causes, such as inflammation of the ureters and bladder, stones, tuberculosis, tumors, etc.

Urethral diseases are often seen in urethral stones, inflammation, tumors, foreign bodies, stenosis, urethral adenitis or abscesses and prostate diseases, such as prostatitis, abscesses, tumors, etc.

3. Seminal vesicle diseases such as seminal vesicle inflammation, abscess, etc.

All of the above kidney diseases will cause high white blood cell count in urine routine.

In case of glomerulonephritis, the number of white blood cells in the urine may increase slightly. If a large number of white blood cells or pus cells are found in the urine, it indicates purulent inflammation of the urinary tract, such as pyelonephritis, cystitis, urethritis or renal tuberculosis. A large number of neutrophils may appear in the urine within 1 week after kidney transplantation, and then gradually decrease and return to normal. Therefore, when the white blood cell count in urine routine test is high, don't panic too much, but objectively eliminate some influencing factors.
