THE TOPOGRAPHY FEATURES OF LEVATOR ANI MUSCLE IN THE INTERMEDIATE FETAL PERIOD OF HUMAN DEVELOPMENT
Abstract
Recently, one of the topical issues of medicine is the problem of pelvic floor dysfunction. The most frequent manifestations of it include urinary incontinence, fecal incontinence, pelvic organ prolapse. The prevalence of urinary and fecal incontinence in old age reaches 50%, and more than 7% need urgent surgical correction of these conditions. Morphological studies of human fetuses allow us to trace in detail the features of the antenatal development of the pelvic floor for a better understanding of the anatomy and pathogenesis of myofascial insufficiency of the supporting apparatus of the pelvic organs.
The aim is to study the topography features of levator ani muscle in the intermediate fetal period of human development.
Material and methods. On fixed human fetuses of 14 to 26 weeks of gestation, morphometry of iliococcygeal part of levator ani muscle insertion to orienteers of chondropelvis was performed.
Results. The study revealed a physiological lowering (descension) of the tendinous arch of levator ani muscle. The process of descension is more pronounced in male fetuses due to more intensive longitudinal growth of pelvic bones; in female fetuses, the process of descension stabilizes at 21 weeks of intrauterine development.
Conclusion. The data obtained demonstrate the sexual features of the intrauterine development of the human pelvic floor in second trimester of gestation and can be used for the treatment of pelvic dysfunctions, taking into account the features of the topography of the tendinous arch of levator ani muscle.
