The causes of pelvic organs prolapse

Normal anatomy of the female pelvis

Normal anatomy of the female pelvis

It occupies the inner part of the pelvis of the woman, which is a cavity situated below the abdomen and is bounded by the bone frame of the pelvis

The uterus, flanked on each side by annexes (Fallopian tubes and ovaries) occupies the central part of that pelvic cavity.

Uterus, Fallopian tubes and ovaries are the internal genital organs of the woman and it is in particular the uterus that the fertilised or fertilized egg (ovum produced by the ovary and fertilized in the tube by a sperm) carries out its ‘nesting’ and the foetus develops, during the entire pregnancy.

The rectum occupies the posterior part of this cavity. It fills the cavity of the sacrum before following a pronounced angle to prolong into the anal channel. Rectum and anus form the terminal part of the digestive tube.

The ‘fall’ of the pelvic organs takes place through the vagina.

The uterus prolapse appears as a projection, a ‘bubble’ either permanent or during effort either within the vagina or at the orifice of the vulva or outside it. It is composed of all or part of the vaginal walls more or less doubled by the bladder. The bladder prolapse is called cystocoele, proctocoel for the rectum, the adjacent peritoneum culs-de sac (elytrocele) as well as the solid vaginal base of the uterine collar (hysterocele).

The vagina, more precisely the ‘uro- genital cleft’, is the point of weakness of the woman’s pelvic floor, on which converge all the forces notably from pushing of the abdomen.

This disorder corresponds therefore to a disturbance of the (static pelvis).
