Investigation of Surgery, Collagenase, and Restorex for the Improvement of Peyronie's

After eligible patients have been informed about the study protocol and risks and consent have been given, men will be randomly assigned into either the collagenase clostridium histolyticum + penile traction therapy (CCH + PTT) group or to the surgery + penile traction therapy (surgery + PTT) group. Those in the CCH + PTT group will receive the full 4 series of 8 Xiaflex injections with 1-3 days between each set of 2 injections and 6 weeks prior to the next series. Patients would then use the RestoreX traction device throughout the series to 3 months post-treatment. Those that were assigned the surgery + PTT treatment protocol would undergo surgery using either penile plication or incision and grafting, depending on the degree of curvature and erectile function. Traction using RestoreX will also be prescribed to these men 2-4 weeks post-operatively until 3 months post-treatment. Key clinical outcomes of both treatment protocols will be compared.
