Finding white blood cells (WBCs) in your urine, a condition called pyuria, can be a sign that something's up with your urinary tract or kidneys. While a small number of WBCs is normal, elevated levels usually indicate an infection, most commonly a urinary tract infection (UTI).
UTIs occur when bacteria enter the urinary tract, causing inflammation and triggering the body to send WBCs to fight the infection. Other possible causes of pyuria include kidney infections, kidney stones, certain medications, and even vigorous exercise.
If your doctor detects WBCs in your urine during a urinalysis, they'll likely order further tests to pinpoint the cause. Don't panic! While it's important to address the underlying issue, many conditions causing pyuria are easily treatable with antibiotics or other medications. Staying hydrated and maintaining good hygiene can also help prevent future UTIs. Talk to your doctor if you have concerns.
