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

Abstract

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.
