Abstract EN
Detailed knowledge of the anatomy of the rhabdosphincter and adjacent tissues is mandatory during urologic surgery to ensure reliable oncologic and functional outcomes.
To characterize the levator ani (LA) function for the urethral sphincter, we described connective tissue morphology between the LA and urethral rhabdosphincter.
The interface tissue between the LA and rhabdosphincter area in males contained abundant irregularly arrayed elastic fibers and smooth muscles.
The male rhabdosphincter was positioned alongside the LA to divide the elevation force and not in-series along the axis of LA contraction.
The male perineal membrane was thin but solid and extends along the inferior margin or bottom of the rhabdosphincter area.
In contrast, the female rhabdosphincter, including the compressor urethrae and urethrovaginal sphincter muscles, was embedded in the elastic fiber mesh that is continuous with the thick, multilaminar perineal membrane.
The inferomedial edge of the female LA was attached to the upper surface of the perineal membrane and not directly attached to the rhabdosphincter.
We presented new diagrams showing the gender differences in topographical anatomy of the LA and rhabdosphincter.
