What are some common causes of microscopic hematuria?

Here are some common causes of blood in the urine:

  • Kidney infections
  • Enlarged prostate
  • Urinary tract (bladder) infection
  • Swelling in the filtering system of the kidneys (this is called "glomerulonephritis")
  • A stone in your bladder or in a kidney
  • A disease that runs in families, such as cystic kidney disease
  • Some medicines
  • A blood disease, like sickle cell anemia
  • A tumor in your urinary tract (this may or may not be cancer)
  • Exercise (when this is the cause, hematuria will usually go away in 24 hours)
