Objective To introduce a new technique for urethral coverage in Snodgrass hypospadias repair,and to evaluate its effectiveness and complications.Methods From April 2003 to February 2006, this new procedure was performed in 289 children with hypospadias aged 3 months to 12 years (mean age,2. 4 years).The native meatus of urethra was identified subcoronal in 78 cases,penile/shaft in 136,penoscrotal in 36 and scrotal in 16;and 23 cases had undergoneⅡstage operation and re-operation.The overlapping coverage with bilateral shaft based vascularized dartos pedicle was done in the new urethra by Snodgrass hy- pospadias repair in these children.Results All the cases were followed for 3 months to 2 years.Postoper- atively,urinary fistulas developed in 32 cases (11%).Of them,11 were cured spontaneously within 4 weeks. The incidence of actual urinary fistula was 7% (21/289).Of the 21 fistulas which were not cured,11 (5%) occurred in 214 cases of distal hypospadias;and 10 (13%) in 75 cases of proximal hypospadias,Ⅱstage and re-operation.No dehiscence and diverticulum was found.Combined with mucosal collar technique,the ventral skin of the penis was sewn on the midline.During the follow-up,excellent cosmetic results with normal-ap- pearing circumcised penis were achieved in most patients.Conclusions Bilateral shaft based vascularized dartos pedicle urethral coverage procedure is a reliable and effective method for preventing urethral cutaneous fistulas and dehiscence.This method can reconstruct a satisfactory cosmetic appearance of the penis.

OBJECTIVETo evaluate some currently used surgical approaches to the correction of congenital penile curvature.
METHODSSeventy-six patients with congenital penile curvature underwent surgical correction, of whom 67 were accompanied with hypospadias, 5 with epispadias and 4 with normal urethral meatus. The methods for straightening the phallus included 5-week preoperative hCG treatment, complete degloving of penile skin, release of periurethral fibrous bands extending proximally to the meatus, plication of dorsal or ventral tunica albuginea, and embedding of dermis and tunica vaginalis grafts.
RESULTSAll the cases were followed up for 2 months to 2 years, and the mean follow-up time was 9.3 months. Satisfactory phallus straightening was achieved in 67 cases (88%), mild residual chordee remained in 6 (8%), which needed no reoperation for the time being unless warranted by follow-up, and relapse occurred in 3 (4%), which needed further operation.
CONCLUSIONMost cases of congenital penile curvature can be corrected sufficiently with the above methods.
