Subtunical microdissection and grafting versus classical plaque incision and grafting for complex Peyronie's disease
Official title: Comparative Outcomes of Subtunical Microdissection and Grafting Versus Classical Plaque Incision and Grafting in Complex Peyronie's Disease
Run by Namik Kemal University · NCT07470528 · Data updated 2026-11-12
This test will see if subtunical microdissection with a bovine pericardial graft corrects severe penile curvature while better preserving erectile function than classic plaque incision and grafting in men with complex Peyronie's disease who need surgery.

Is this trial a fit for you?
✓Likely a good fit
Men aged 18 or older with stable, complex Peyronie's disease (severe or multiplanar curvature, hourglass or hinge deformity) who require graft-based surgical reconstruction and can complete follow-up are ideal candidates.
✕Probably not a fit
Patients with ossified plaques needing excision, congenital curvature, active/progressive disease, prior penile prosthesis or reconstructive surgery, severe unresponsive erectile dysfunction, or serious systemic illness are unlikely to benefit or are excluded.

What this trial studies
This interventional study compares two graft-based surgical techniques for complex Peyronie's disease at a single center in Tekirdag, Turkey. Eligible men with stable, complex deformities will undergo either subtunical microdissection with grafting or classical plaque incision and grafting, with the same bovine pericardial graft material and graft sizing determined by geometric principles. The subtunical microdissection technique uses microsurgical dissection beneath the tunica under magnification to release plaque-related deformity while aiming to preserve tunical integrity. Outcomes will focus on correction of curvature and preservation of erectile function, along with graft- and surgery-related complications during postoperative follow-up.
Why it matters
Potential benefit: If successful, the subtunical microdissection approach could correct deformity while reducing the risk of postoperative erectile dysfunction and graft-related complications.
How similar studies have gone: Classical plaque incision and grafting is an established standard for complex cases, while subtunical microdissection is a newer technique with limited published data and not yet widely validated.
