Plain-English summary
Ten male Beagle dogs underwent a surgical procedure where a piece of muscle tissue was wrapped around the penis to help improve urinary control. Before the surgery, the dogs had a certain level of urethral pressure, which increased significantly after the procedure and continued to improve over the following ten weeks. This technique showed promise for treating male urinary incontinence by enhancing urethral pressure.

Abstract
PURPOSE: It was the aim of this study to investigate the possibility of pedicled rectus abdominis muscle fascial flap wrapped around the penis for enhanced urethral pressure in dogs. MATERIALS AND METHODS: Ten adult male Beagle dogs underwent a procedure in which surrounding tissue of the penis at the site of the bulbomembranous urethra was dissected and a pedicled rectus abdominis muscle fascial flap was wrapped around the penis. Profilometry of the urethral pressure was carried out before, during and after the operation in all dogs. RESULTS: Before the operation, the mean maximal urethral pressure (MUP) was 48.9 +/- 11 cm H(2)O, and the mean MUP was 78.3 +/- 20.5 cm H(2)O after the penis was surrounded by a rectus muscle flap. There was a significant difference (t = 4.99, p = 0.0007). Ten weeks after the operation, the mean MUP was 88.3 +/- 22.4 cm H(2)O, which was significantly higher than that before the operation (t = 6.0584, p = 0.0002). CONCLUSIONS: A pedicled rectus abdominis muscle fascial flap wrapped around the penis can raise the urethral pressure. This provided an experiment basis for treating male urinary incontinence with a pedicled rectus muscle flap.
