Biomatrices in Urethral Reconstruction

Abstract

Urethral reconstruction is still a big challenge in urology. Traditionally, the penile skin or buccal mucosa was used as graft for replacement. However, the morbidity of the donor site was reported previously. Furthermore, there is a lack of an adequate autologous donor graft in many cases. The tissue engineered urethra may provide an alternative to the reconstruction. Herein, we reviewed the biomatrices for urethral substitution either in animal model or in clinical cases.
