In urethral stricture disease, the Barbagli flap urethroplasty uses tissue from which donor site?

• A Buccal mucosa graft (BMG) from the inner cheek ✓
• B Penile skin (Orandi flap)
• C Split-thickness skin from the thigh
• D Tunica vaginalis flap

Explanation

The Barbagli technique (dorsal onlay buccal mucosa graft urethroplasty) uses a buccal mucosa graft harvested from the inner cheek or lower lip. Buccal mucosa is the preferred graft material for urethral reconstruction due to its hairless, well-vascularised, pliable nature and resistance to urinary environment. The graft is inlaid onto the dorsal urethral surface, quilted to the corpus spongiosum, and is associated with long-term patency rates >80%. The Orandi flap uses penile skin as a pedicled flap. Split-thickness skin grafts have higher contraction rates in the urethra.
