Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Feasibility of nerve monitoring, defined as ability to record compound nerve action potentials from the cavernous nerve during surgery.

Secondary Outcome Measures

Name	Time	Method
1. Feasibility of functional monitoring, defined as ability to evoke an increase in tissue oxygenation as a result of cavernous nerve stimulation during surgery.<br>2. Change in preoperative to postoperative erectile function, based on a patient-completed questionnaire (IIEF-5) at three months and six months.
