Urethral plate salvage with dorsal graft promotes successful penile flap onlay reconstruction of severe pendulous strictures.

Abstract

A modified 1-stage penile flap onlay reconstruction is presented for patients with a long stricture in whom the urethral plate is deficient or absent. Of 37 patients who underwent transverse penile island flap onlay urethroplasty 3 men and 1 boy required simultaneous augmentation (2) or replacement (2) of an inadequate urethral plate. The 15-year-old boy had persistent severe chordee after multiple hypospadias procedures. A dorsal buccal mucosal graft was used in 3 cases and cadaveric dermal graft was used in 1. The goal of dorsal graft application in each case was to create a uniform urethral plate 1 cm. wide to promote successful 1-stage penile flap onlay reconstruction. No patient has required further instrumentation and all void without difficulty. In the 15-year-old boy chordee has completely resolved. Using dorsal grafts to salvage an inadequate urethral plate during 1-stage penile island flap onlay reconstruction obviates flap tubularization.
