The rectouterine pouch (or Patrick-Douglas Bursa, or Ehrhardt-Cole Recess, or Pouch of Douglas) is the extension of the peritoneal cavity between the
rectumand back wall of the uterusin the female human body.
The rectouterine pouch is used in the treatment of end-stage
renal failurein patients who are treated by peritoneal dialysis. The tip of the dialysis catheter is placed into the deepest point of the pouch.
In "women" it is the deepest point of the peritoneal cavity, posterior to (behind) the uterus and anterior to (in front of) rectum. (The pouch on the other side of the uterus is the
It is near the posterior
fornix of the vagina.
In men, the region corresponding to the rectouterine pouch is the
Rectovesical excavation, which lies between the urinary bladderand rectum. (There is no equivalent to the vesicouterine excavation.)
The rectouterine pouch, being the lowest part of the peritoneal cavity in a woman who is standing, is a common site for the spread of pathology such as
ascites, tumour, endometriosis, pus, etc.
It is also known by the names "Douglas pouch", "Douglas cavity", "Douglas space" and "Douglas cul-de-sac". [WhoNamedIt|synd|2937]

anatomistDr James Douglas ( 1675– 1742) who extensively explored this region of the female body. Three other nearby anatomical structures are also named for him - the Douglas fold, the Douglas lineand the Douglas septum.
