Typically, microscopic hematuria indicates damage to the upper urinary tract (kidneys), while visible blood indicates damage to the lower tract (ureters, bladder, or urethra). But this is not always the case.
Inflammation of the kidney, usually of unknown cause
Strenuous exercise, especially running, results from repeated jarring of the bladder. In one study, 24% of runners who competed in an ultra-long-distance marathon had hematuria after the race. The hematuria disappeared within
seven days. A 20% incidence has been found in marathon runners.
Sometimes no cause is found for blood in the urine.
If serious conditions such as cancer, kidney disease, and other chronic diseases that cause kidney damage or bleeding are ruled out, the cause is usually not serious.
The hematuria will probably go away by itself or continue as a chronic condition without doing harm. Any changes should immediately trigger a return visit and evaluation by your health-care provider.
Urine can be colored pink, red, or brown for reasons that have nothing to do with bleeding in the urinary tract:
Foods: beets, berries, and rhubarb in large amounts
Medications: Different medications can change your urine color (Phenazopyridine [Pyridium], a pain reliever affecting the lower urinary tract, can change urine color to orange.).
