PURPOSE: The objective of this study was to evaluate the effects of intratunical injection of platelet rich plasma (PRP) for the treatment of Peyronie's disease (PD) in a rat model.
MATERIALS AND METHODS: Twenty male Sprague-Dawley rats (300-350 g) were randomly divided into 4 groups: sham, PD, PD + PRP, and PRP. The PD + PRP groups received intratunical injections with 0.1 mL PRP on day 15 (treatment) or day 0 (PRP effect). Forty-five days following transforming growth factor-beta 1 injection, rats underwent pathological examination. Tissues were evaluated histologically for fibrosis grade (Haematoxylin & Eosin staining), collagen/smooth muscle ratio (Masson Trichrome staining) and type III/type I collagen ratio (Picro-sirius red staining). Statistical analysis was performed by Kruskal-Wallis and chi-square followed by the Mann-Whitney U test for post hoc comparisons.
RESULTS: Significant changes were found in all 3 groups compared to the sham group (p < 0.0001 for fibrosis, p = 0.001 for collagen/smooth muscle ratio and p = 0.003 for type III/type I collagen ratio). The values in the PRP group and the findings in the PD group are similar (p = 0.122 for fibrosis, p = 0.221 for collagen/smooth muscle ratio and p = 1.0 for type III/type I collagen ratio).
CONCLUSION: This is the first study of PRP on PD. As a result of pathological examinations, PRP shows PD-like effects in rats. PRP may be a cheap, easily accessible, and an effective disease model for PD treatment research.
