Objective To investigate the cause and management of urethral dehiscence after hypospadias repair. Methods 23 cases of urethral dehiscence after hypospadias repair were reviewed.According to the location of meatus and the status of available skin, urethroplasty was performed by preputial island flap, scrotal island flap or bladder mucosa translocation. Results 23 cases were followed up from 1 to 9 years.15 cases were cured.3 developed urethral fistulae after the secondary repair, which were subsecondary closed up successfully by Thiersch procedure,4 had stricture at the anastomosis site or at the meatal stenosis , which were cured by a silastlic tube stent ( 1.5~5.0 months ). 1 had a mild penile curvature yet erection was satisfactory. Conclusions Preputial or scrotal island flap translocation should be the primary choice of secondary urethral reconstruction, whereas bladder mucosa graft is used in case of local skin deficiency.A secondary surgery should be performed by experceinced uro pediatric surgeons.
