Blood in the urine can originate from a number of structures and organs especially those that make up the urinary system such as the kidney, the ureter, the bladder and the urethra.

Usually, the presence of blood in the urine will disappear after some rest or around 72 hours after the activity. However, it is also worth noting that if you have a pre-exsiting kidney condition or any other problems related to the urinary system, vigorous exercise can further exacerbate the damage of this condition and also lead to the hematuria.

Such cancer includes prostate cancer and bowel cancer. In addition, prostate enlargement can also encroach the bladder and cause the same symptom.
