Blood (hematuria) may be a problem in the kidney, ureter (connection duct to), bladder, prostate gland (in men), and/or urethra.

Hematuria: Large intermittent blood loss as you describe can often be ascribed by open bleeding tiny blood vessels. This diagnosis would require a kidney angiogram to localize any blood leak, because they can "plug it up" in radiology. Sometimes you never catch it when it starts bleeding. This is called angiodyspasia, not uncommon. Cystoscopy will look for bladder source of bleeding. ...Read more
