ABSTRACT
Objective To discuss the indication and efficacy for treating hypospadias with ure-throplasty of Pedicled preputial double-faced island flap(PPDIF). Methods Records of 99 children (mean age, 5.1 years; age range, 4 months-12 years)with hypospadias who underwent PPDIF oper-ation were reviewed. Of them, 56 cases were penile type of hypospadias, 24 cases of penile root type, 13 cases of scrotal type and 6 cases of perineal type according to Barcat classification. Based on Duck-ett technique, the partial preputial cortical plate remained and was displaced to gastr-penis with ure-thra. , and finally the new urethra would be covered by the cortical plate. Results During follow-up of average 2 years, 8 patients(8. 1%) developed urethral fistula, 1 (1.0 %) developed mild meatal ste-nosis, and 1(1.0 %) developed flap necrosis. The success rate for total PPDIF procedure was 89.90 % (89/99). And the success rate of simple PPDIF for cases with penile and penile root hypospadias, and PPDIF+Duplay for cases with serotal and perineal hypospadias were respectively 91.25 % (73/80) and 84.21%(16/19). respectively. Conclusions PPDIF is good for treating most hypospadias. Furth-more it make penis better shape. In the severe cases, PPDIF+Duplay prededure is recommended and the effect was affirmative.
