There is wide variability in sexual potency rates 9-86 after prostate cancer surgery due to our limited understanding of the location of the cavernous nerves, which are responsible for erectile function. Advances in identification and preservation of these nerves would result in improved postoperative potency and patient quality of life. We hypothesize that application of three optical technologies for identification, imaging, and preservation of the nerves during prostate surgery will result in improved sexual function 1 Laser nerve stimulation for identification, optical coherence tomography OCT for nerve imaging, and 3 precise laser prostate dissection for nerve preservation. Year 1 was devoted to optimization of laser stimulation parameters and comparison with electrical stimulation. We completed these tasks and then started on Year 2 aims, including assembly of a laparoscopic laser nerve stimulation probe, and improving OCT image quality for differentiating nerves and prostate. We have published our results 2 manuscripts, 5 conference proceedings, and 3 abstracts.
