[Autonomic innervation of the female pelvis. Anatomic basis].

The pelvic plexus with its sympathetic (hypogastric nerves, sacral sympathetic trunk) and parasympathetic (pelvic splanchnic nerves) sources provides and distributes the autonomic nervous supply for the pelvic organs. This homogeneous autonomic nerve plate is located within and deeply to the peritoneal fold (recto-uterine in the female pelvis) lying medially to the internal iliac vessels. Autonomic nerve fibres emerge from the pelvic plexus and travel to the anterolateral aspect of the rectum and the inferolateral and posterolateral aspects of the bladder and female genital tract. In addition, pelvic organs are innervated by nerves accompanying the vessels and the ureter which penetrate the pelvic plexus. Knowledge of the topography of the pelvic plexus indicates the most common sites for iatrogenic lesions and should help us in avoiding postoperative autonomic dysfunction.
