Straining to pee, stretching the bladder and forceful urination can cause irritations to the bladder and urethral linings and cause blood in the urine. Irritations around the urethral opening that are caused by excessive wiping, urinary leakage, and rashes, can also cause blood cells to be seen in the urine test. These problems usually cause small amounts of blood to be present in the urine that is not seen with the naked eye (microscopic hematuria).
The blood may go unnoticed unless a physician tests the urine. If a primary care physician discovers blood in the urine, then further testing and x-rays may be performed to rule out infection and other abnormalities. Frequent and complete emptying of the bladder, good local hygiene, and avoidance of irritation to the private parts can prevent blood in the urine and avoid potentially unnecessary medical treatment.
