Figure 6: Overviews of cross sections of rabbit posterior urethras. In Group 1, part of the tubularized buccal mucosa graft survived in the neourethra at 1 month. At 3 months, excessive contracture of the tubularized BMG was observed. In Group 2 animals, there was no evidence of epidermal lining on the luminal surface of the neourethra 1 month postimplantation. At 3 months, the urethral caliber was narrowed, although some discontinued epidermal layers developed on the luminal surface of the neourethra. In Group 3, the neourethra lumen was lined with typical squamous epithelial layers, and the constructed neourethra maintained a wide urethral caliber for 3 months. Scale bars = 1.0 mm.
