The use of a polyglycolic acid polymer graft in Peyronie's disease - preliminary outcomes.

Abstract

Plaque incision and grafting is indicated for patients with Peyronie's Disease [PD] and severe curvature, complex deformities or for patients with significant penile shortening. To date, no graft studied has been considered ideal. The aim of this study is to conduct a descriptive analysis about functional results with the use of a bioabsorbable graft for PD treatment. A single-center, retrospective evaluation of a cohort of patients who were treated by plaque incision and grafting with a polyglycolic acid polymer graft (Gore® Bio-A®) between 2018 and 2021 was conducted. Correction of penile curvature was the main outcome. Loss of penile sensitivity, de novo erectile dysfunction and any other adverse event were the secondary endpoints. 14 patients were included in this study (mean age 59.5 ± 7.2 years). The median follow-up time was 12 months (range 3-12). The curvature correction rate was 78.5%. Glans hypoesthesia was present in one of 14 patients (7.1%) and refractory erectile dysfunction was reported in 64.2%. None of the patients presented any major adverse event based on Clavien-Dindo classification. Curvature correction and changes in penile sensitivity rates were similar to those found in the literature. No major surgical complications, such as graft rejection, infection, and extrusion, occurred in this sample. Although a population with a higher prevalence of erectile dysfunction was included in this sample, higher rates of refractory erectile dysfunction were observed and these findings should be confirmed in further studies.
