ABSTRACT
<p><b>OBJECTIVE</b>To investigate the indications and clinical effect of using oral mucosa as the graft in hypospadias repair.</p><p><b>METHODS</b>We performed hypospadias repair using oral mucosa for 19 patients, 10 with the urethral opening at the root of the penis, 7 at the scrotum and 2 at the perineum. Of these patients, 8 had received urethroplasty once, and 6 twice, unsuccessfully, and 7 of them were complicated by penile chordee. The lower lip mucosa was used as the graft for 14 cases, and the buccal mucosa for the other 5. Fifteen cases received autologous oral mucosa onlay for repair, with the new urethra covered by the dartos coat of the dorsal skin. For the other 4 cases, whose urethral plates had been damaged in the previous operations, oral mucosa strips were used to substitute the urethral plates to get the penis straightened, followed by urethroplasty 6 months later.</p><p><b>RESULTS</b>Of the 19 patients, 17 (89.5%) achieved satisfactory results, with a desirable shape of the penis and a vertical slit-like meatus at the tip of the glans. Chordee was corrected in all the patients. No urethral stricture was found during the 3 - 18 months follow-up. Urethral fistula occurred in 2 cases because of infection, but cured by surgical repair 6 months later.</p><p><b>CONCLUSION</b>Using oral mucosa as the graft is an effective surgical option for hypospadias repair.</p>
