Complete labial fusion causing urinary retention in a postmenopausal woman.

Labial fusion or labial adhesion can rarely be encountered postmenopausal and may be diagnosed in advanced stages especially in sexually inactive women. It may be a rare cause of voiding dysfunction or urinary retention. We present a case of a postmenopausal woman presenting with urinary retention due to complete labial fusion. The patient was treated both with topical estrogen and surgical separation of labial fusion. No recurrences developed after the procedure. Topical estrogen treatment may not resolve adhesions in postmenopausal women and invasive procedures may be necessary to resolve urinary retention.
