Introduction. Peyronie's disease is a sexual medicine condition that may adversely affect male sexual function. Aim. To provide expert opinions/recommendations concerning state-of-the-art knowledge for the pathophysiology, diagnosis and treatment of Peyronie's disease. Methods. An International Consultation in collaboration with the major urology and sexual medicine associations assembled over 200 multidisciplinary experts from 60 countries into 17 committees. Committee members established specific objectives and scopes for various male and female sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respective sexual medicine topic represent the opinion of experts from five continents developed in a scientific and debate process. Concerning the Peyronnie's disease committee, there were 10 experts from six countries. Main Outcome Measure. Expert opinions/recommendations are based on grading of evidence-based medical literature, extensive internal committee discussion over 2 years, public presentation and deliberation. Results. Peyronie's disease is characterized by an inflammatory response beneath the tunica albuginea with fibroblast proliferation forming a thickened fibrous plaque that may cause penile pain, penile curvature and erectile dysfunction. Medical treatments have been described but few prospective controlled trials have revealed significant clinical benefits. Surgical treatments (penile plication, Nesbit excision, plaque incision and grafting and penile prosthesis insertion) should be considered after Peyronie's disease has stabilized. Surgical outcome studies reveal that a stable deformity is best corrected with the least postoperative ED by a Nesbit procedure. Plaque incision and grafting should be reserved for men with good erectile function and marked penile shortening although there is a higher prevalence of postoperative ED. Implantation of a penile prosthesis is an excellent option for men with an accompanying erectile deficit. Conclusions. Safe and effective treatments for Peyronie's disease examined by prospective, placebo-controlled, multi-institutional clinical trials are needed.
