Overview
Pyuria is a urinary condition characterized by a high number of white blood cells in the urine. It is generally characterized as the presence of 10 or more white blood cells per cubic millimeter in a sample of urine, 3 or more white cells per high-power field of unspun urine, a positive result on Gram's staining of an unspun urine specimen, or a urinary dipstick test that is positive for leukocyte esterase. Pyuria most commonly occurs in urinary tract infections (UTI) and/or sepsis. Other causes include sterile pyuria, STDs, pneumonia, interstitial cystitis, kidney stones, pelvic infections and urinary fistulas. Long-term usage of some medications, including aspirin, diuretics, nitrofurantoin, PPIs and NSAIDs, induces pyuria. There may be visible changes in the urine, which may appear cloudy or thick or look like pus.
