Optimal Modeling: an Updated Method for Safely and Effectively Eliminating Curvature During Penile Prosthesis Implantation

To assess outcomes of a variant of traditional modeling (“optimal modeling,” OM) in patients with residual curvature following prosthesis implantation. We performed a retrospective review of all patients who underwent penile implant insertion. Patients with >30° of residual curvature after cylinder placement and inflation underwent OM and were compared 1:1 to a demographically-matched cohort who received implantation without ancillary straightening. Optimal modeling was performed by forcibly bending the erect penis in the direction opposite the point of maximal curvature while maintaining glanular pressure to prevent urethral injury. This was performed for 90-second intervals for as many cycles as necessary to achieve
