FIG. 4.

Retrograde urethrograms were performed for the assessment of urethral caliber at 2 weeks, 1 month, 2 months, and 6 months postimplantation. Urethral strictures were observed in both the BAMG and Und-rASCs/BAMG groups at 2 weeks and 1 month postimplantation (urethrocutaneous fistula developed in one animal in the Und-rASCs/BAMG group); at 2 months postimplantation, the stricture of the urethra was slightly improved compared with the formers. In the Epith-rASCs/BAMG group, a mild stricture of the urethra was observed at 2 weeks postimplantation, and 1 month after the surgery, the stricture was significantly improved. Arrow indicates the replaced part of urethra.
