Buccal Mucosa Graft in Urological Surgery: A State-of-the-Art Review an Expert Opinion

Background/Objectives: Buccal mucosa graft (BMG) is increasingly utilized in reconstructive urological surgeries due to its versatility, robust integration, histological characteristics and low morbidity at the donor site. Initially employed in urethral surgery, BMG use has expanded to complex ureteral and penile reconstructive procedures. This narrative review examines BMG applications in various urological surgeries, comparing its outcomes to other graft types, with a focus on surgical techniques and patient outcomes. Methods: A narrative review was conducted using PubMed and Scopus to identify relevant studies published over the last three decades on the use of BMG in urological reconstructive surgery. Articles in English addressing BMG harvesting, applications, and functional outcomes were analyzed. Results: BMG has demonstrated high success rates in every field of its application, especially in urethral reconstruction with an 83-91% efficacy rate in intermediate follow-up. Studies have also reported positive outcomes in complex ureteral and penile curvature surgeries, with patient satisfaction rates reaching up to 85%. Conclusions: BMG is an adaptable tissue graft for urological reconstructive surgeries, offering favorable outcomes with minimal morbidity. Although current results are encouraging, larger prospective studies with standardized protocols are necessary to fully validate its long-term efficacy and optimize treatment approaches for complex urological reconstructions.
