Surgical correction of penoscrotal transposition associated with hypospadias and bifid scrotum: our experience of two stage repair.

OBJECTIVE: To assess the results of surgical correction of incomplete penoscrotal transposition and bifid scrotum using the Glenn-Anderson technique, and its impact on subsequent definitive urethroplasties and final outcome. PATIENTS AND METHODS: We retrospectively reviewed 31 children that underwent two-stage repair for incomplete penoscrotal transposition with severe hypospadias and bifid scrotum. Patient age at stage 1 ranged from 12 to 24 months (average 16 months). The operative principle was based on achieving a normal anatomical position of the penis and scrotum using the Glenn-Anderson technique. In cases with associated scrotal or perineal hypospadias this was transformed into a penoscrotal hypospadias. Final stage urethroplasty was performed after a period of 6 months with a modified Thiersch-Duplay technique. RESULTS: Cosmetic and functional results of the Glenn-Anderson operation were excellent. No major complications were observed. Of 31 patients, 12 (38%) had complications secondary to urethral repair. CONCLUSION: The Glenn-Anderson technique for reconstruction of penoscrotal transposition and bifid scrotum is a simple technique, free of major complications. The purpose of this intervention is to improve the cosmetic appearance and function of the penis. A minimum period of 6 months between consecutive urethroplasties is important. The final stage guarantees good functional and cosmetic results preserving the prepuce.
