Here is what can bring blood into urine:

Urinary Tract Infection

One of the commonest causes of hematuria is urinary tract infection (UTI). These generally occur because of bacterial infection where they multiply in the urethra. In the elderly, blood might not be visible with the naked eye in urine but under a microscope.

Kidney Infection or Stones

Also known as pyelonephritis, this is a condition characterized by a bacterial infection in the kidney. Here, bacteria enter to the kidney from the bloodstream or move from ureters. Kidney stones may also be the cause of hematuria.
