ABSTRACT
Replacement of damaged or diseased tissues has been one of the most challenging aspects in medicine. Tissue replacement within the urinary tract is a technically demanding procedure, particularly urethral reconstruction which has posed a continuing challenge to the reconstructive urologist. Various techniques utilizing flaps or grafts (genital/extragenital), whether single or multistage, have been used in the armamentarium of urethral reconstruction with satisfactory results. However, in complex and recurrent cases, enough non-hirsute genital skin is not always available in amount and quality. Although different types of grafts have been employed including split-thickness and full-thickness skin, bladder mucosa, and buccal mucosa grafts (which have become the favored graft for urethral substitution),1 yet they may not always be sufficient to bridge long defects.
