Sagittal section of the lower part of a female trunk, right segment. (Excavatio vesicouterina labeled at bottom right.)
The epiploic foramen, greater sac or general cavity (red) and lesser sac, or omental bursa (blue). Uterovesical excavation labeled at bottom left, third from the bottom.
In human female anatomy, the 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 retroversion of the uterus, which can frequently complicate pregnancies.
The vesicouterine excavation is close to the anterior fornix of the vagina.
