摘　　要：Background:Repair of proximal hypospadias remains a challenge with no consensus on the best surgical approach.Several reports have shown recurrence of chordee after plate-preserving techniques.In this report,we present our experience in managing cases who presented with persistent/recurrence of chordee after tubularized incised plate(TIP)repair for proximal hypospadias.Methods:Between 2015 and 2023,the study included eight patients who presented with ventral penile curvature after previous hypospadias repair in infancy(TIP urethroplasty).Reoperation to correct persistent ventral curvature was performed several years after the primary TIP repair(3-15 years;mean 7.9 years;median 7.5 years).The reoperation was a two-stage procedure:the first stage comprised transection of the urethra and grafting(lower lip mucosal graft);the second stage(6 months later)was a Thiersch-Duplay urethroplasty.Results:Complications included poor taking of the graft after the first stage in one case(12.5%),which was regrafted using buccal(cheek)mucosa.Complications after second stage included urethro-cutaneous fistulae in five(62.5%)that were successfully surgically treated at a later stage.Follow-up after second stage ranged between 6 months and 7 years(mean 2.4 years;median 1 year).Satisfaction with reoperation to correct penile curvature was noted by parents as well as older children(adolescents)who appreciated better cosmesis by increasing ventral penile length and improved curvature.Conclusion:Preservation of the urethral plate in proximal hypospadias may result in shortened penile length,mostly on the ventral aspect.A two-stage reoperation to increase the length of the penile urethra can successfully reverse this complication.
