Our experience with a dermal patch graft urethroplasty is presented in 10 Pitman-Moore minipigs. Histologic review at various post-urethroplasty intervals showed epithelialization of the graft. In addition, several cases in which this technique was used are presented with early followup. The advantages of dermal patch urethroplasty as well as the application of dermal grafts in other areas of the urinary tract are discussed.
