Introduction.  Peyronie's disease (PD) is characterized by fibrotic plaque formation within the tunica albuginea, leading to penile deformity, angulation, painful erections, and often, erectile dysfunction. There is limited knowledge of its etiology and pathophysiology. Currently, there is no standardization for reporting the evaluation and treatment outcomes. No consensus exists on the ideal management of PD. Aim.  The aim of this study is to review the use of radiation therapy (RT) for the treatment of PD. Methods.  This study used a review of the literature and informed expert opinion. Main Outcome Measures.  The main outcome measures are the reported improvement with regard to pain, curvature, plaque size, and erectile function as well as a review of the safety profile of RT. Results.  Radiation has been used for the empirical treatment of PD with mixed results throughout the literature. Low-dose RT in the early stages of PD seems to be effective in patients with painful erections not improving with time or with the use of oral or intralesional therapies. Comparison with other current medical therapies is difficult due to the absence of criteria for therapeutic success and the absence of randomized, controlled trials. Multiple studies have demonstrated varied results in terms of curvature reduction, plaque volume, and sexual functioning. The absence of the use of validated means of measuring penile deformity and sexual function, the limited relevance of plaque and pain improvement combined with the potential negative consequences of radiation on erectile tissue structure and function lead us to make a recommendation that RT not be used for the management of PD. Conclusions.  In clinical practice, mixed success for RT has led to the recommendation against its use as a treatment modality for PD. Mulhall JP, Hall M, Broderick GA, and Incrocci L.
