Decline in the elevator antimuscle tone is caused either by denervation or by direct muscle trauma, and hence resulting in an open urogenital hiatus
, which, combining with the functional and anatomic alterations in the muscles and nerves of the pelvic floor, contribute to the development of POP.
Their study reported that sitting position stretches the puborectalis muscle which slightly closes urogenital hiatus
, thus ausing slight obstruction at urogenital hiatus
during micturition, at sitting position independent to presence or absence of any bladder outlet obstruction.
Size of urogenital hiatus
as a potential risk factor for emptying disorders after pelvic prolapse repair.
The vaginal suspensory axis is a continuum of connective tissue that serves as the primary structure to hold the central pelvic organs above the levator plate and behind the urogenital hiatus
. The named components of this axis are the perineum, rectovaginal septum, pericervical ring, uterosacral ligaments, and presacral periosteum.
"We're relying on native endopelvic connective tissue to close the urogenital hiatus, which is unique in colpocleisis techniques," said Dr.
Traditional colpocleisis closes the urogenital hiatus without specifically identifying the perivaginal endopelvic fascial septa, while using some degree of vaginectomy.
