What causes high white blood cells in urine flow?

Under normal circumstances, elevated white blood cells in urine flow may be related to factors such as intense physical exercise, urethritis, chronic glomerulonephritis, acute cystitis, and pyelonephritis. Patients are advised to follow medical guidance for symptomatic treatment. Specific analyses are as follows:

1. Intense Physical Exercise

After intense physical activity, white blood cells deposited on the blood vessel walls may enter the circulatory system, leading to an increased number of white blood cells in the urine, resulting in elevated white blood cells in urine flow. In such cases, symptoms usually resolve within a few days through rest and increased fluid intake.

2. Urethritis

Urethritis is an inflammation of the inner lining of the urethra, commonly caused by bacterial infections, sexually transmitted diseases, or other inflammatory conditions, which can lead to elevated white blood cells in urine. Patients may take medications such as metronidazole tablets or tinidazole tablets as directed by a physician.

3. Chronic Glomerulonephritis

Glomerulonephritis refers to impaired glomerular filtration function due to infections, diseases, or other causes, manifesting as hematuria, proteinuria, edema, and other symptoms. If patients with glomerulonephritis fail to properly manage their condition, resulting in inflammatory infection, the aforementioned symptoms may occur. Patients may take medications such as prednisone acetate tablets or compound captopril tablets as prescribed.

4. Acute Cystitis

Acute cystitis is an acute inflammatory condition of the bladder wall caused by nonspecific bacterial infections. Main symptoms include frequent urination, urgency, dysuria, discomfort in the bladder or perineal area, and a burning sensation in the urethra. Severe cases may present with urgent urinary incontinence, cloudy urine, and the presence of white blood cells in the urine, thus causing the above symptoms. Patients may be treated with medications such as cefradine capsules or levofloxacin hydrochloride capsules as directed by a doctor.

5. Pyelonephritis

Pyelonephritis is an inflammatory disease caused by kidney infection. It is typically accompanied by a significant increase in white blood cells in urine flow and may present with additional symptoms such as fever, flank pain, and frequent urination. Patients may be treated with medications such as amoxicillin-clavulanate potassium tablets, ampicillin-sulbactam sodium for injection, or levofloxacin hydrochloride injection as prescribed.

In addition, elevated urinary white blood cells may also be associated with factors such as urinary tract stones or urinary obstruction. It is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
