A study of one-stage repair using pedicled preputial double-faced island flap combining with Duplay urethroplasty on severe hypospadias

Objective To retrospectively summarize the clinical application and efficacy of the Pedicled preputial double-faced island flap (PPDIF) combining with Duplay procedure in patients with severe hypospadias.Methods From January 1998 to March 2010,72 children (ranging from 10M to 12Y,mean age 4.1 years) with severe hypospadias underwent one-stage urethroplasty by using PPDIF combining with Duplay procedure,which included 50 scrotal type patients and 22 perineal type patients.Results The mean follow-up time was 23 months.The straightening and outlook of the penis were satisfactory,and the meatus located at normal anatomical position after operation.10 cases (13.9％) were complicated with fistula and 4 (5.6％) were complicated with urethral stenosis after operation.80.6％ of patients get the better curative efficacy.Conclusions PPDIF combining with Duplay procedure is better approach to treat severe hypospadias.It can bring the benefits to patients involving better cosmesis,less urethral stenosis and fistula incidence.
