Urinary White Blood Cells: Causes, Prevention, and Treatment - Urology

More Info

---

The presence of white blood cells (WBCs) in urine, known as pyuria, can indicate an underlying medical condition, and it is generally considered abnormal. White blood cells are part of the immune system and their presence in urine often suggests inflammation or infection in the urinary tract, kidneys, or bladder.

Causes of Increased WBCs in Urine
1. Urinary Tract Infections (UTIs): The most common cause of elevated WBCs in urine is a urinary tract infection. Bacteria invade the urinary system, leading to inflammation and an immune response, which results in increased WBCs.

2. Kidney Infections (Pyelonephritis): This is a more severe form of UTI that affects the kidneys. It can cause significant symptoms and requires prompt treatment.

3. Interstitial Cystitis: This chronic condition causes bladder inflammation and can lead to increased WBCs in urine.

4. Kidney Stones: The presence of stones can irritate the urinary tract, leading to inflammation and an increase in WBCs.

5. Other Conditions: Conditions such as glomerulonephritis, prostatitis in men, and sexually transmitted infections can also lead to elevated WBCs in urine.


Prevention
Preventing elevated WBCs in urine largely revolves around maintaining urinary tract health:
1. Hydration: Drinking plenty of fluids helps flush bacteria from the urinary tract.

2. Hygiene: Proper personal hygiene, especially for women, can help prevent infections. Wiping from front to back after using the toilet can reduce the risk of bacteria entering the urinary tract.

3. Urination Habits: Urinating after sexual intercourse can help flush out bacteria that may have entered the urinary tract.

4. Diet: A healthy diet that includes foods rich in antioxidants can support the immune system.

5. Regular Check-ups: Regular medical check-ups can help catch any potential issues early.


Treatment
The treatment for elevated WBCs in urine depends on the underlying cause:
1. Antibiotics: If a UTI is diagnosed, antibiotics are typically prescribed. It's crucial to complete the entire course of antibiotics even if symptoms improve.

2. Pain Management: Over-the-counter pain relievers may help alleviate discomfort associated with urinary tract infections.

3. Follow-up Tests: If WBCs remain elevated after treatment, further testing may be necessary to rule out other conditions, such as kidney disease or interstitial cystitis.

4. Lifestyle Changes: Making lifestyle changes, such as improving hydration and hygiene practices, can help prevent future infections.

5. Specialist Referral: If recurrent infections or elevated WBCs persist, a referral to a urologist or nephrologist may be warranted for further evaluation and management.


Conclusion
In summary, the presence of white blood cells in urine is typically indicative of an underlying issue, most commonly an infection. It is essential to consult a healthcare provider for a proper diagnosis and treatment plan. Preventative measures can significantly reduce the risk of urinary tract infections and associated complications. If you experience symptoms such as frequent urination, burning sensation during urination, or lower abdominal pain, seeking medical attention promptly is crucial. Regular monitoring and maintaining a healthy lifestyle can also contribute to urinary tract health.
