Neuroanatomic basis for traction-free preservation of the neural hammock during athermal robotic radical prostatectomy

Abstract

Much of the progress achieved in the past two decades in improving potency outcomes after radical prostatectomy has resulted from an improved appreciation of the anatomic basis of the nerves responsible for erection. We review the current literature evaluating the neuroanatomy of prostate and operative strategies for better preservation of sexual function. Recent studies suggest an alternative and more complex course of nerves than previously described. Periprostatic nerves can be divided into three broad surgically identifiable zones: the proximal neurovascular plate, the predominant neurovascular bundle, and the accessory neural pathways. Better appreciation of the variable and often invisible anatomical course of the cavernosal nerves continues to engender innovations in surgical technique to optimize their preservation. Improved anatomic understanding has optimized surgical technique in order to improve potency outcomes following radical prostatectomy.
