Rectal Mucosa Graft Take in Staged Urethroplasty.

ABSTRACT

When an oral mucosa graft is not a viable option for urethroplasty, colonic mucosa grafts have served as a promising alternative since described by Igor A. Thyrmos in 1902.1 In previous studies, colonic mucosa graft retrieval required sigmoid resection2-3 which limited adoption of this technique. We previously described the success of a minimally-invasive transanal endoscopic microsurgical technique of rectal mucosa graft harvest for urethroplasty.4 Here, we pictorially demonstrate the take of a transanal endoscopically harvested rectal musosa graft used in a 2-stage anterior urethroplasty (to our knowledge, the first such 2-stage procedure) with 6 months of follow-up.
