[Reflectory stimulation of the pudendal nerve in dynamic pharmaco-cavernosometry]

A prospective study was performed in 20 patients to assess the impact of vibratory glans stimulation on the course and results of dynamic pharmaco-cavernosography and cavernosometry. An intracorporeal pressure rise was achieved with lower amounts of saline when stimulation was applied and in some cases could not be provoked by saline infusion without glans stimulation. False-positive diagnoses of diffuse venous leakage could thus be eliminated. The data presented in this paper confirm the need for stimulation of the pudendal reflex arch to achieve physiological conditions. The simplicity of the procedure and the minimal time requirement suggest its clinical routine application of vibratory glans stimulation during cavernosography and cavernosometry.
