Hematuria is the presence of blood in the urine, which can be visible to the naked eye (gross hematuria) or detectable only under a microscope (microscopic hematuria). It can originate from any part of the urinary tract, including the kidneys, ureters, bladder, prostate (in men), and urethra.
The prognosis for hematuria depends on the underlying cause and the effectiveness of the treatment. Many causes of hematuria are treatable, especially if detected early. Persistent or recurrent hematuria requires thorough evaluation to rule out serious conditions, such as cancer or chronic kidney disease.
