The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and ...
The vesicouterine pouch is a fold of peritoneum over the uterus and the bladder, forming a pelvic recess. [1] It is continued over the intestinal surface and body of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
The rectouterine pouch, being the lowest part of the peritoneal cavity in a woman at supine position, is a common site for the spread of pathology such as ascites, tumour, endometriosis, pus, etc. As it is the furthest point of the abdominopelvic cavity in women, it is a site where infection and fluids typically collect.

Culdoscopy is an endoscopic procedure performed to examine the rectouterine pouch and pelvic viscera by the introduction of a culdoscope through the posterior vaginal wall. [1] The word culdoscopy (and culdoscope) is derived from the term cul-de-sac, which means literally in French "bottom of a sac", and refers to the rectouterine pouch (or called the pouch of Douglas).
The pelvic inlet is typically used to divide the abdominopelvic cavity into an abdominal (above the inlet) and a pelvic cavity (below the inlet). Sometimes, the pelvis cavity is considered to extend above the pelvic inlet, and in this case the pelvic inlet is used to divide the pelvic cavity into a false (above the inlet) and a true pelvis ...
Pelvic fascia extends to cover the organs within the pelvis. It is attached to the fascia that runs along the pelvic floor along the tendinous arch. The fascia which covers pelvic organs can be divided according to the organs that are covered: The front is known as the "vesical layer". It forms the anterior and lateral ligaments of the bladder.
The vagina is attached to the pelvic walls by endopelvic fascia. The peritoneum is the external layer of skin that covers the fascia. This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness. It permits some shifting of the pelvic structures.
As might be expected, the contents of the urogenital triangle differ greatly between the male and the female. Some of the components include: [1] Posterior scrotal nerves / posterior labial nerves; Urethra; Vagina; Bulbourethral gland / Bartholin's gland; Muscles Superficial transverse perineal muscle; Ischiocavernosus muscle; Bulbospongiosus ...
