Optical Coherence Tomography of Cavernous Nerves: A Step Toward Real-Time Intraoperative Imaging During Nerve-Sparing Radical Prostatectomy.
OBJECTIVES: To demonstrate the use of optical coherence tomography (OCT) for imaging of the cavernous nerve (CN) and periprostatic tissues. The rates of nerve preservation and postoperative potency after radical prostatectomy might improve with better identification of the CN using emerging intraoperative imaging modalities. OCT is an imaging modality that allows for real-time, high-resolution, cross-sectional imaging of tissues. METHODS: Seven male Sprague-Dawley rats underwent surgery using a midline celiotomy to expose the bladder, prostate, and seminal vesicles. The CNs and major pelvic ganglion were identified. Visual identification of the CN was further confirmed by electrical stimulation with simultaneous intracorporeal pressure ...Read Full Article
