Gynecologists who practice this sub-specialty are called urogynecologists and urologists who practice this sub-specialty are called female urologists. In the United States, urogynecologists have completed medical school and a four-year residency in obstetrics and gynecology and female urologists have completed medical school and a five-year residency in urology. These doctors become specialists with additional training and experience in the evaluation and treatment of conditions that affect the female pelvic organs, and the muscles and connective tissue that support the organs. The additional training focuses on the surgical and non-surgical treatment of non-cancerous gynecologic problems. A few practitioners have completed a board-accredited fellowship in female pelvic medicine and reconstructive surgery after completing a residency in urology or obstetrics and gynecology. The first fellowship received accreditation in 1996. As of January 2010, there were 30 fellowship programs approved by both the American Board of Obstetrics and Gynecology and the American Board of Urology . These fellowships are three-years for obstetrician-gynecologists and two-years for urologists. Thus, the combined duration of training for female pelvic medicine and reconstructive surgery is seven years after medical school for both urologists and gynecologists. The International Urogynecology Journal publishes a listing of world-wide training programs. Urogynecology involves the diagnosis and treatment of urinary incontinence and female pelvic floor disorders. Incontinence and pelvic floor problems are remarkably common but many women are reluctant to receive help because of the stigma associated with these conditions. "There is no more distressing lesion than urinary incontinence-A constant dribbling of the repulsive urine soaking the clothes which cling wet and cold to the thighs, making the patient offensive to herself and her family and ostracizing her from society" Although countless women are bothered by a loss of bladder control, bowel symptoms, and pelvic discomfort they are often not aware that these problems have a name much less how common they really are. Pelvic floor conditions are more common than hypertension, depression, or diabetes. One in three adult women have hypertension; one in twenty adult women have depression; one in ten adult women have diabetes; and, more than one in two adult women suffer from pelvic floor dysfunction.
