The use of oral mucosa in urethral surgery
Why ?
• Its biological and histological characteristics
• Due to its elasticity, it is adaptable for any kind of urethroplasty(one-stage or two-stage) (onlay or inlay)
• In the literature (years 1966-2006), 1.267 articles on the useof oral mucosa for urethral reconstruction have been reported
