High-resolution Map of Somatic Periprostatic Nerves

Abstract

Objective To generate a high-resolution map of periprostatic somatic nerves. Periprostatic nerves are at risk of injury during radical prostatectomy; this study aimed to establish the location of somatic nerves with respect to the prostate and the neurovascular bundle. Materials and Methods Hemiprostates from patients in whom a wide local excision was performed were evaluated. Representative sections from the base, midzone, and apex of the prostate were stained with Masson's trichrome and antineuronal nitric oxide synthase antibodies, to identify myelinated and parasympathetic nerves, respectively. Somatic nerves were identified as neuronal nitric oxide synthase negative myelinated nerves. S..
