Urogenital diaphragm

Urogenital Diaphragm

The Urogenital Diaphragm is a layer of the pelvis that separates the deep perineal sac from the upper pelvis, crossing the area of the urethra and vagina in women, and the urethra in men. It is a structure of the anatomy of the pelvic floor.

Etymology

The term "urogenital" is derived from the Greek words "ouron" meaning urine and "genitalis" meaning to generate. The term "diaphragm" is derived from the Greek word "diaphragma" meaning partition.

Structure

The Urogenital Diaphragm is composed of the deep transverse perineal muscle, the sphincter urethrae muscle, and the superior fascia of the urogenital diaphragm. It is a triangular shape, with its base towards the pubis, and its apex towards the rectum. The Urogenital Diaphragm is pierced by the urethra and, in women, the vagina.

Function

The Urogenital Diaphragm plays a crucial role in maintaining continence. It supports the pelvic organs and helps to control the release of urine and feces. It also plays a role in sexual function.

Clinical Significance

Damage to the Urogenital Diaphragm can lead to urinary incontinence and fecal incontinence. It can also lead to pelvic organ prolapse, where the pelvic organs drop from their normal position.
