Comparative Outcomes of Subtunical Microdissection and Grafting Versus Classical Plaque Incision and Grafting in Complex Peyronie's Disease

Plain-language summary

The goal of this clinical study is to compare two surgical techniques used for the treatment of complex Peyronie's disease. Peyronie's disease can cause penile curvature, deformity, and difficulties during sexual intercourse due to fibrotic plaques within the penile tunica albuginea. In patients with severe deformity, surgical correction is often required. The main question this study aims to answer is whether subtunical microdissection can provide effective correction of penile curvature while preserving erectile function when compared with the classical plaque incision and grafting technique. Participants with complex Peyronie's disease who require surgical correction will undergo either subtunical microdissection or classical plaque incision and grafting. In order to standardize the procedures, the same graft material will be used in both surgical techniques. A bovine pericardial graft will be applied in all cases, and graft size will be determined according to the geometric principles described by Egydio. In the subtunical microdissection technique, the subtunical plane beneath the Peyronie's plaque is carefully dissected using microsurgical instruments under approximately 3.5× optical magnification with surgical loupes. In the classical technique, plaque incision is performed followed by graft reconstruction of the tunical defect. All surgical procedures will be performed by the same surgical team using a standardized operative approach and a uniform anesthesia protocol. Participants will be followed prospectively after surgery to evaluate penile curvature, erectile function, and patient satisfaction. The results of this study may help determine whether subtunical microdissection represents an effective and safe alternative surgical strategy for the treatment of complex Peyronie's disease.
