The ligaments that maintain the normal position of the uterus are the round ligament, the broad ligament, the uterosacral ligament and the main ligament. When these four pairs of ligaments are functioning normally, the uterus maintains a normal physiological position of anterior tilt and forward flexion. If these pairs of ligaments become decompensated, the uterus will end up in an abnormal position, and even prolapse as the woman grows older. If the prolapse of the uterus progresses to a certain level, clinical manifestations such as urinary incontinence, urination disorders, and fecal discharges may occur. At this time it is necessary to give appropriate attention and sometimes even surgical intervention is required.
