Objective Assessment of Residual Nerve Tissues in Radical Prostatectomy Specimens by Immunohistochemical Staining of Neuronal Nitric Oxide Synthasee-positive Nerves and Its Impact on Postoperative Erectile Function

摘要

OBJECTIVE To compare the quality of surgical management of the neurovascular bundle (NVB) by assessment of neuronal nitric oxide synthase (nNOS)-positive nerves in surgical specimens between open retropubic radical prostatectomy (RP; ORRP) and robot-assisted RP (RARP).
