Pyuria
The finding of more than four white blood cells per high-power field on a urine specimen is suggestive of urinary tract inflammation, although as with hematuria, the precise site is not identified. Pyuria as an isolated finding is most commonly associated with bacterial urinary tract infection. When associated with hematuria or proteinuria, pyuria is suggestive of parenchymal renal disease such as glomerulonephritis or interstitial nephritis.
The presence of pyuria should initiate a search for urinary tract infection, particularly when the patient complains of dysuria, flank pain, or fever. Renal imaging studies are often indicated to exclude the presence of renal parenchymal scarring, obstruction, or abscess formation, particularly when accompanied by signs of renal dysfunction such as azotemia.
