Full Answer

An enlarged prostate typically causes blood in the urine in men around middle age, says Mayo Clinic. Other symptoms include difficulty urinating or an urgent need to urinate.

Kidney or bladder stones happen when the minerals that the bladder filters out crystallize along the walls of the kidney or bladder, states Mayo Clinic. Over time these crystals sometimes become stones, which are generally painless until they either cause a blockage or are being passed. Another symptom of a kidney or bladder stone is intense pain.

Urinary tract infections happen when bacteria travel back up the urethra and into the bladder, according to Mayo Clinic. Sometimes the only symptom of an infection, especially in older men, is a tiny amount of blood in the urine.

Kidney disease and cancer are less common causes of blood in the urine. In some cases kidney disease is a product of another disease, such as diabetes, but sometimes has its own causes, says Mayo Clinic. Visible urinary bleeding sometimes signifies cancer in the prostate, bladder or kidney.
