ABSTRACT

Buccal mucosal graft (BMG) urethroplasty has emerged as an ideal substitute for the surgical management of long
segment urethral strictures due to its superior structural and functional properties. BMG offers a thick, resilient
epithelium, rapid revascularization, and minimal donor site morbidity, making it the preferred graft material for
substitution urethroplasty.[4][7] Clinical studies demonstrate high success rates exceeding 85% even in strictures
exceeding 4 cm, with effective use in dorsal, ventral, lateral, or combined grafting techniques.[6] Compared to
other graft sources like penile skin flaps, BMG shows lower recurrence and complication rates. While long-term
recurrence remains a challenge, ongoing advances including tissue-engineered buccal mucosa aim to improve
durability and reduce donor site morbidity. Overall, BMG urethroplasty represents the current gold standard for
reconstructing complex and long anterior urethral strictures with satisfactory functional and anatomical outcomes.
In our institute we perform Dorsal ONLAY BMG for long segmental (>2cm) stricture in all cases.[19]
