Abstract Background Adjuvant maneuvers are often necessary to correct residual curvature during inflatable penile prosthesis (IPP) placement in patients with Peyronie's disease (PD). Aim We present our multicenter experience using collagen fleece as graft material for plaque incision and grafting (PIG) during IPP placement in patients with moderate to severe PD. Methods We retrospectively reviewed 51 patients with IPP from 3 sites who underwent PIG with Tachosil (Baxter, IL) collagen fleece. Coloplast (Minneapolis, MN) IPP devices were used. Factors associated with residual curvature, revision, and patient satisfaction were performed using chi-squared analysis. Outcomes We evaluated postoperative outcomes including factors associated with residual curvature, revision, and patient satisfaction. Results The mean compound curvature was 69.6°. The mean follow-up was 10.6 (range 1–38) months. All patients reported erections sufficient for penetrative intercourse at the last follow-up. Residual curvature <15° was noted in 6 of 51 (12%) patients. 3 patients required device revision. 2 patients experienced temporary glanular paresthesia, and no patients experienced device infection. Clinical Implications In our multicenter study, patients experienced substantial curve correction with minimal complications, and in the few patients who had persistent mild curvature, severe preoperative curvature (>60°) was found to be the only risk factor. Strengths & Limitations Our study represents the largest series of patients coming from multiple centers undergoing surgical correction of PD with IPP and collagen fleece grafting. Limitations of this study include the retrospective study design, lack of a comparison group, and modest follow-up. Conclusion PIG using collagen fleece is a safe and effective means of correcting residual curvature after IPP placement in patients with moderate to severe PD.
