What causes high white blood cells in routine urine test?

Elevated white blood cells in routine urine tests may be caused by dietary irritation, prolonged exposure to cold, urethritis, prostatitis, kidney stones, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Dietary irritation: The metabolic process of proteins in the body may lead to a mild increase in white blood cells in the urine. Therefore, long-term high-protein diets—such as consuming eggs, beef, and similar foods—may cause the aforementioned symptoms. Generally, reducing intake of high-protein foods will allow the discomfort to resolve on its own after some time, so there is no need for excessive concern.

2. Prolonged exposure to cold: The body may produce a stress response to maintain body temperature, which could result in elevated white blood cells in the urine. It is recommended to avoid staying in cold environments for extended periods and to take proper measures to stay warm, which can help alleviate symptoms.

3. Urethritis: This may be related to factors such as heavy alcohol consumption or prolonged sitting. When bacteria invade and multiply in the urinary tract, they may irritate the urinary mucosa, causing an inflammatory response and increased white blood cells. Patients are advised to follow medical instructions and use medications such as azithromycin granules, cefixime granules, or roxithromycin tablets for treatment.

4. Prostatitis: This may be associated with improper sexual activity or excessive fatigue. After onset, prostatic congestion may lead to inflammatory changes, thereby increasing white blood cells in the urine. Patients are advised to follow medical instructions and use medications such as minocycline hydrochloride capsules, celecoxib capsules, or Qianlieshutong capsules for treatment.

5. Kidney stones: These are usually caused by urinary tract obstruction or urinary tract infections. As stones move within the urinary tract, they may damage the urinary mucosa, easily triggering an inflammatory response and elevated white blood cells. Patients are advised to use medications such as tamsulosin hydrochloride sustained-release capsules, potassium sodium citrate granules, or dl-anisodamine tablets under medical supervision to improve symptoms.

In daily life, patients are advised to maintain a light diet, engage in appropriate physical activities such as running or walking, drink plenty of warm water, all of which are beneficial for recovery.
