Abstract

PURPOSE: Since Food and Drug Administration approval of collagenase Clostridium histolyticum for Peyronie's disease, there has been significant debate regarding its role and comparable efficacy to surgery.

MATERIALS AND METHODS: A randomized, controlled trial was performed of Peyronie's disease men treated with either collagenase C histolyticum + RestoreX penile traction therapy + sildenafil or penile surgery + RestoreX penile traction therapy + sildenafil, with 3-month data presented. Primary objectives were overall satisfaction, subjective changes in erectile function, penile sensation, penile length, and changes in the International Index of Erectile Function-Erectile Function Domain score. Secondary outcomes included objective changes in length, curve, adverse events, and other standardized and nonstandardized questionnaires.

RESULTS: A total of 40 men were enrolled, with 38 (collagenase C histolyticum group = 19, surgery group = 19) completing treatment and having 3-month data available. All demographic and clinicopathological variables were similar between groups. Following treatment, 50% of men in the collagenase C histolyticum group reported being very satisfied (vs 21% in the surgery group, P = .08) and noted better subjective erectile function (100% vs 68%, P = .03) and penile length (88% vs 16%, P < .0001), lesser impacts on penile sensation (75% vs 11% no change, P < .001), and similar International Index of Erectile Function-Erectile Function Domain changes…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 40 participants or records.
