PURPOSE: Rather than resecting the distal spongiosum lateral to the open urethra for hypospadias, we mobilized this tissue with the urethral plate away from the corpora cavernosa, subsequently wrapping it around various types of urethroplasty to prevent fistula formation. MATERIALS AND METHODS: The distal spongiosum was preserved and used for coverage in 25 hypospadias repairs in 1 year. We initially applied it in this manner when the distal spongiosum persisted as a pillar of healthy erectile tissue but later when the distal tissue appeared more fibrous in nature. The wrap was used to cover various types of urethroplasty, including advancement in 6 cases, tubularization in 10, flip-flap repair in 6 and an island onlay pedicle graft in 3. RESULTS: All patients have at least 1 year of followup. There has been no fistula formation or residual chordee. In 1 patient minor meatal retraction did not require a secondary procedure. Cosmetic results have been good. CONCLUSIONS: A distal wrap of corpus spongiosum may be used to avoid fistula formation without causing residual or recurrent curvature. It re-creates a nearly normal urethra in some cases.
