[Autologous buccal mucosal graft for urethral reconstruction]

To search for a new method for urethra reconstruction using autologous buccal mucosal graft while lacking of local skin.

Since 1998, a total of 25 patients with complex hypospadias have been treated using buccal mucosal grafts for urethral reconstruction. The reconstructed urethra was anastomosed with the meatus half year later.

All the reconstructed urethra survived without contracture or stricture except one infection, which healed with no adverse consequence.

The key points for operation success is rich capillary network, thick epidermis and thin lamina propria of the buccal mucosa. Buccal mucosa is an excellent tissue for urethral reconstruction.
