Causes of High White Blood Cells in Urine
Disease description:
I went to the hospital for a physical examination this week, and the doctor told me that my urine white blood cell count was high. I would like to ask the doctor, what are the causes of elevated white blood cells in urine?
Doctor's answer (1)
Dr. Luo Yong
Elevated white blood cells in urine represent a common abnormal finding in routine urinalysis, often indicating inflammation or infection in the urinary system.
1. The most common cause is a urinary tract infection (UTI), such as cystitis or urethritis. Bacterial invasion of the urinary tract triggers an inflammatory response, leading to an increased number of white blood cells as the body fights the pathogens.
2. Kidney diseases and urinary tract stones may also cause elevated white blood cells in urine. These conditions can damage the mucous membranes of the urinary tract, inducing an immune response.
3. In some cases, transient elevation of white blood cells in urine may occur following strenuous exercise, cold exposure, or other similar conditions.
When elevated urinary white blood cells are detected, patients should seek timely medical attention. Additionally, maintaining good personal hygiene is important to prevent worsening of the condition.
