Gross hematuria (visible blood in the urine
) along with flank pain
in a 50-year-old male can have more than one cause.
Infection along the the urogenital system & kidney stones are the most common. Other things such as malignancy and a ruptured cyst are also possible. A red urine may not always be blood & "urethra pain" may not be urethra pain. A doctor should be consulted for these symptoms.
