- Abstract:
- Objective To report the outcomes of using buccal mucosa graft placed over pedicled external spermatic fascia flap plus onlay adjacent penile skin flap for single-stage correction of children with unsuccessful re-operative hypospadias.Methods Between 2014 and 2017,13 re-operative hypospadias children underwent correcting penile curvature by transecting adjacent scarred urethral plate or keloid and anastomosing unilateral external spermatic fascia flap to ventral surface of corpus cavernosum for dorsal penile urethral defect.A buccal mucosa graft was placed directly on the top of flap and an onlay adjacent penile skin flap employed for one-stage urethroplasty.A urethral catheter was inserted for 3 weeks and then removed.Results Repair was successful in all cases.During a mean follow-up period of 12-40 months,penile cosmetic appearance was decent.There was no residual chordee.For two cases of postoperative urethrocutaneous fistula,one case presented with obstructive pattern uroflowmetry due to meatal stenosis while another child developed glans dehiscence.Conclusion In this preliminary clinic report,failed hypospadias repair has been successfully managed with single-stage correction using buccal mucosa graft over pedicled external spermatic fascia flap plus onlay adjacent penile skin flap urethroplasty.More studies are necessary for further elucidating the role of grafting over flap in the correction of failed re-operative hypospadias.
