ABSTRACT
OBJECTIVES: To develop a technique for urethral reconstruction using a combined labia minora flap and buccal mucosa graft. Urethral lengthening is the most difficult part in female transsexuals and poses many challenges. METHODS: From April 2005 to February 2008, 38 patients (aged 19-53 years) underwent single-stage metoidioplasty. The technique starts with clitoral lengthening and straightening by division of both clitoral ligaments dorsally and the short urethral plate ventrally. The buccal mucosa graft is quilted to the ventral side of the corpora cavernosa between the native orifice and the tip of the glans. The labia minora flap is dissected from its inner surface to form the ventral aspect of the neourethra. All suture lines are covered by the well-vascularized subcutaneous tissue originating from the labia minora. The labia majora are joined in the midline and 2 silicone testicular implants are inserted to create the scrotum. The neophallus is covered with the remaining clitoral and labial skin. RESULTS: The median follow-up was 22 months (range 11-42). The median neophallic length was 5.6 cm (range 4-9.2). The total length of the neourethra was 9.4-14.2 cm (median 10.8). Voiding while standing was reported by all 38 patients, and temporary dribbling and spraying were noted by 12. Two fistulas and one urethral erosion resulted from the testicular implant and required secondary revision. CONCLUSIONS: A combined buccal mucosa graft and labia minora flap present a good choice for urethral reconstruction in female-to-male transsexuals, with minimal postoperative complications.

AIM OF THE STUDY: Urethral reconstruction in severe hypospadias presents a great challenge. We evaluated a method of combining longitudinal dorsal island skin flap and buccal mucosa graft to create a neourethra in the most severe hypospadias. Our aim was to repair the most difficult cases in a one-stage procedure. METHODS: Between January 2003 and July 2007, 23 patients (aged from 9 to 26 months) underwent repair of severe hypospadias (18 penoscrotal and 5 scrotal forms). The short urethral plate is divided in all cases and the remaining curvature was repaired by dorsal plication. The buccal mucosa graft is harvested and fixed to the ventral side of corpora cavernosa to form the first half of the neourethra. A longitudinal dorsal island skin flap is created and buttonholed ventrally. It is sutured to the buccal mucosa graft to form the neourethra. An abundant flap pedicle is fixed laterally to cover all the suture lines of the neourethra. Penile skin reconstruction is done using available penile skin. RESULTS: The mean follow-up was 27 (range 11-66) months. Satisfactory results were achieved in 20 patients. There were two urethral fistula and one temporary distal urethral stricture. CONCLUSION: A combined longitudinal island skin flap and buccal mucosa graft could be a good choice for single-stage urethral reconstruction in the repair of the most severe hypospadias.
