[Postoperative impotence].

Increasing interest has developed in recent years about the preservation of sexual function after urological surgery. The pelvic plexus which is formed by parasympathetic visceral efferent preganglionic fibers that arise from the sacral center provides autonomic innervation to the corpora cavernosa. The cavernous nerves emerge from the pelvic plexus and then travel along the posterolateral portion of the seminal vesicle and prostate and then along the membranous urethra. The preservation of the nerve supply of the corpora during urological and pelvic procedures is of vital importance to preserve potency.
