hematuria
(he″mә-)
(hem″ә-tu´re-ә)
the discharge of blood in the urine, making the urine either slightly blood-tinged, grossly bloody, or a smoky brown color.
Microscopic examination of a urine specimen can reveal red blood cells not evident to the naked eye; however, this microscopic hematuria is not always significant. Gross hematuria that is visible to the naked eye is symptomatic of disease or injury to a part of the urinary system. Bladder tumors, cystitis, urethritis, and small kidney stones passing along the ureter can cause hematuria. Other causes include vascular diseases, some types of kidney disorders, and (sometimes but not always)
traumatic injury to the kidney.
