Materials and Methods: Subepithelial biopsies of the urethral plate were obtained in 17 boys, including 13 with distal and 4 with penoscrotal hypospadias. Ventral penile curvature was noted in 5 cases. Specimens were evaluated by 7 light microscopy after hematoxylin and eosin staining. Results: All biopsies demonstrated well vascularized connective tissue comprised of smooth muscle and collagen. There was no evidence of fibrous bands or dysplastic tissue. Conclusions: The urethral plate consists of epithelium overlying connective tissue. We found no histological evidence of fibrous cords historically considered responsible for chordee.
