Recto-uterine fold

Recto-uterine fold (also known as Douglas' fold) is a structure in female anatomy that is part of the peritoneum, the serous membrane that forms the lining of the abdominal cavity. It is one of the two ligaments that serve as the boundary of the recto-uterine pouch, the other being the vesico-uterine fold.

Anatomy

The recto-uterine fold extends from the front of the rectum to the back of the uterus. It is formed by the peritoneum draping over the uterus and rectum, creating a pouch-like space known as the recto-uterine pouch or Douglas' pouch. This is the lowest point of the abdominal cavity when a woman is in the supine position.

Clinical significance

The recto-uterine fold and the pouch it helps form have clinical significance in gynecology and obstetrics. In cases of pelvic inflammatory disease (PID), pus can accumulate in the recto-uterine pouch, causing pain and discomfort. This can be detected during a bimanual examination.

In addition, the recto-uterine pouch is often the site of ectopic pregnancy. This is a medical emergency that requires immediate attention.
