Human’s levator ani muscle & rectum syntopic relations in the light of classic and digital morphologic methods’ data

Abstract

Recently, one of the most pressing issues of modern medicine is pelvic floor dysfunction, which includes pelvic organ prolapse, urinary and fecal incontinence []. The leading role in maintaining the pelvic organs is assigned to levator ani muscle. The study of attachment features of muscle to pelvis, rectum will clarify the pathogenesis of pelvic floor insufficiency and development of incontinence symptoms and pelvic organs prolapse. The use of classical morphological and innovation technologies of «Autoplan» hardware and software complex using MRI data made it possible to identify morphologically denser and sparse zones of the wall of the distal rectum, directly related to the attachment of levator ani muscle fibers to it.
