ABSTRACT

<p><b>OBJECTIVE</b>To discuss the treatment of congenital hypospadias in infancy.</p><p><b>METHODS</b>After correction of chordee, the tubed oral mucosa was used to prefabricate urethra in penis as free graft. The urethral anastomosis was performed at the second stage. The scrotum fascia flap, pedicled with scrotal artery, was transferred to cover the penile defect.</p><p><b>RESULTS</b>From Jan. 2007 to May 2010, 42 cases were treated. The tubed oral mucosa was 3.0-4.0 cm in length, and 0.6-0.8 cm in diameter. The maximum size of scrotum flap was 1.5 cm x 3.0 cm. Urethral fistula happened in two cases due to necrosis at the distal end of scrotal flap, which was healed spontaneously after dressing for 1-2 weeks. Primary healing was achieved in all the other cases. After operation, the 26 cases have been visited for 6 months to 3 years, no urethra fistula , narrow and the penis curved. There is an universal urinate for oneself and a good form.</p><p><b>CONCLUSIONS</b>The tubed oral mucosa can be used to prefabricate urethra, which is anastomosed at the second stage. The tubed oral mucosa combined with scrotal fascial flap which has a reliable blood supply, is very suitable for hypospadias in infancy.</p>
