What Is It?
Dysuria is the medical term for pain or discomfort when urinating. Often described as a burning sensation, dysuria most commonly is caused by bacterial infections of the urinary tract.
Lower urinary tract infection (cystitis or bladder infection) — Dysuria is a common symptom of a bladder infection (cystitis). Cystitis is very common in women aged 20 to 50.
An infection often starts when bacteria enter the opening where urine comes out (urethra) during sexual intercourse. Bacteria also can enter the urethra in women and girls who wipe with toilet tissue from back to front. Once bacteria enter a woman's urethra, it only has to travel a short distance to the bladder.

Pyelonephritis is more common in women than in men.
Urethritis — Urethritis is an inflammation of the urethra. It is usually caused by sexually transmitted diseases (such as chlamydia and gonorrhea). Urethritis also can be caused by contact with an irritating chemical (such as antiseptics, bubble bath or some spermicides) or by irritation from an object, such as a tube (catheter) inserted to drain urine.
Vaginitis — Vaginitis is an inflammation of the vagina. It can be caused by an allergic reaction to an irritating chemical (spermicide, douche, bath soap), a low level of estrogen after menopause, or an object such as a tampon that was not removed. It can also be caused by infection. Common infections include:
