Pyuria

A small amount of white blood cells or (and) pus cells are allowed in normal human urine. Urine sediment microscopic examination, uncentrifuged urine, leukocytes with more than 5 per high-power field of view, centrifugal urine per high-power field with more than 10 fields are classified as abnormal. If white blood cells or pus cells become a pus cell full field of view, the above situation occurs when the urinary tract infection . Infection is called upper urinary tract infection in the renal pelvis and renal nipples; infection in the bladder and urethra is called lower urinary tract infection, and when the specific part is not clear clinically, it is generally called urinary tract infection or urinary system infection. Pelvic nephritis with stones, deformities and stenosis is called complex pyelonephritis, otherwise it is called simple pyelonephritis. Chronic pyelonephritis can be diagnosed if the pyelonephritis persists for more than half a year, if the pyelonephritis is deformed or the surface of the kidney is uneven, or if the kidneys are more than 1 cm in size, or if the renal tubules are persistently abnormal. Chronic pyelonephritis cannot be diagnosed solely by time. Fresh centrifugal urine has more than 5 or 1 hour white blood cells per high power field of vision. Fresh urine white blood cells with more than 400,000 or 12 hours urine more than 1 million urine are called leukocyte urine. Because the degenerated leukocytes are called pus cells, they are also called pyuria.
