Y-duplication of the male urethra: use of anterior anorectal wall for posterior urethral lengthening.
We have approached two patients with Y-duplication of the male urethra by a new two-staged technique to provide better results. A strip of anterior anorectal wall in continuity with the posterior urethra was used for posterior urethral lengthening and a tubed pedicled prepucial flap was used to reconstruct the anterior urethra without using the native urethra. This was done under a covering colostomy. After a gap of 6 months to allow for healing of the anorectum and to ensure adequate functioning of the perineal neourethra, second stage reconstruction was done using buried scrotal tube for the mid urethra along with colostomy closure. On follow-up at 8 and 12 months, respectively, both children were well with no stricture or fistula. There was normal anal continence and no stenosis. This technique tackles the problem in Y-duplication of the male urethra of lengthening the posterior urethral channel, which is often difficult to bring to the anterior half of the perineum especially if the opening is high up in the anorectum (case 2).
