Predictors of treatment success after collagenase Clostridium histolyticum injection for Peyronie's disease: development of a nomogram from a multicentre single‐arm, non‐placebo controlled clinical study

To build a nomogram able to predict treatment success after collagenase Clostridium histolyticum (CCH) for Peyronie's disease (PD).Between November 2016 and November 2017, we enrolled 135 patients with PD into a multicentre single-arm prospective study. All patients enrolled received CCH treatment. Success of therapy was defined as a decrease in penile curvature (PC) of ≥20° from baseline. Treatment satisfaction was assessed using a scale from 1...
