Several organic and functional disorders of the urinary bladder, reproductive tract, anorectum, and the pelvic floor musculature cause pelvic pain. This article describes functional disorders in which chronic pelvic and anorectal pain cannot be explained by a structural or other specified pathology. Currently, these functional disorders are classified into urogynecologic conditions or cystitis and painful bladder syndrome, anorectal disorders, and the levator ani syndrome. Although nomenclature suggests that these conditions are distinct, there is considerable overlap of their symptoms and these disorders have much in common.
