[Neurological and vascular preservation during laparoscopic radical prostatectomy].

The objective of the cavernous nerve preservation is to avoid injury of the unmyelinated nerve fibers and arteries destined to the corpora cavernosa. Dissection anatomical plans could be inter or extra fascial allowing complete or partial neurovascular bundle preservation. The technique is chosen according to the carcinological evaluated risk and anatomical characteristics. Accessory pudendal arteries preservation must be performed when such an artery is identified in order to improve the chance of recovery of spontaneous erections.
