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.

摘要

目的

本研究旨在探讨带蒂腹直肌肌筋膜瓣包裹阴茎以提高犬尿道压力的可能性。

材料与方法

10只成年雄性比格犬接受了一项手术，在球膜部尿道部位解剖阴茎周围组织，并将带蒂腹直肌肌筋膜瓣包裹在阴茎周围。对所有犬在手术前、手术中和手术后进行尿道压力轮廓测定。

结果

手术前，平均最大尿道压力（MUP）为48.9±11 cm H₂O，在阴茎被腹直肌瓣包裹后，平均MUP为78.3±20.5 cm H₂O。存在显著差异（t = 4.99，p = 0.0007）。手术后10周，平均MUP为88.3±22.4 cm H₂O，显著高于手术前（t = 6.0584，p = 0.0002）。
