The use of collagen fleece (TachoSil) as grafting material in the surgical treatment of Peyronie's disease. A comprehensive narrative review.

Grafting for the treatment of Peyronie's disease (PD) can be performed with autologous grafts, allografts, xenografts and synthetic grafts, with all available materials presenting their own characteristics. Still, there is a current arising interest in the use of collagen fleece (TachoSil) as grafting material. We generated an extensive literature review, aiming to assess the use of TachoSil in the treatment of PD. TachoSil is currently indicated in men with PD and preserved erectile function for defect closure after partial plaque excision or incision. In addition, it is indicated for residual curvature correction during penile prosthesis implantation (PPI) in patients with PD and severe erectile dysfunction. Our literature search identified 12 studies evaluating the role of TachoSil for PD surgical treatment. We presented the surgical procedure of TachoSil grafting for the treatment of complex penile curvatures with or without simultaneous PPI and summarized the available evidence on the matter. Identified studies suggest that TachoSil is considered highly effective, reliable and safe in patients with PD. Moreover, it displays favorable properties compared to other grafting materials. It should be stressed that, despite some limitations of available data, TachoSil presents key strengths, which include easy application, decreased operative times, no risk of damaging the implant during PPI, preservation or increase in penile length, fewer cases of penile hypoesthesia, low risk of other adverse events, additional hemostatic effects and low cost. Still, randomized trials comparing TachoSil with different grafting materials are necessary to establish its efficacy.
