There are a number of causes for hematuria (hee-ma-TOUR-ree-uh), or blood in the urine. It may be a result of chronic kidney inflammation; an infection of the urethra, bladder, prostate gland, or kidney; stones in the bladder or kidneys; or even cancer of the bladder, kidneys, or prostate.

Urinary incontinence is a loss of urine control. It is usually caused by an underlying condition such as a urinary tract disorder or a problem with the nerves that control the bladder.

The body is equipped with a filtering system for disposing of liquid wastes. It's called the urinary tract. In women especially, this system is subject to invading bacteria, which can get inside the urinary tract and multiply, resulting in infection and discomfort.

The kidneys 'clean' your blood by filtering out excess water and waste, which then becomes urine. During this process, minerals in the urine may crystallize inside the kidney, and form tiny stones.
