Abstract: Peyronie's disease is a localized connective tissue disease characterized by an active, inflammatory phase and a stable, quiescent phase, with the eventual development of collagenous plaques within the tunica albuginea of the penis. Risk factors primarily associated with Peyronie's disease include Dupuytren's contracture, penile trauma, and family history. A variety of treatment strategies have been utilized, including oral and topical agents, electromotive drug administration, intralesional injections, extracorporeal shockwave therapy, penile traction, and surgery. However, most of these strategies are ineffective, with surgery being the only definitive treatment. Collagenase clostridium histolyticum is a newly US Food and Drug Administration-approved agent for intralesional injection. It is thought to downregulate many of the disease-related genes, cytokines, and growth factors and degrade collagen fibers. It also suppresses cell attachment, spreading, and proliferation. Collagenase clostridium histolyticum has been clinically proven to be a safe and effective therapeutic option, demonstrating decreases in penile curvature and plaque consistency, as well as increases in patient satisfaction. During clinical evaluation, the Peyronie's Disease Questionnaire was validated as an effective tool for assessing treatment outcomes.
