Vesico-uterine pouch

In human female anatomy, the vesico-uterine pouch, vesicouterine excavation (or uterovesical pouch of Meiring) is a second, but shallower, pouch formed from the peritoneum over the uterus and bladder, continued over the intestinal surface and fundus 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. Also termed Dunn's pouch, this is an important anatomical landmark for chronic endometriosis. Endometrial seeding in this region causes cyclical pain in women of child bearing age. Dunn's pouch is also an important factor in a retroverted uterus, which can frequently complicate pregnancies.
