The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) behind (retro) the peritoneum. It has no specific delineating anatomical structures. It has no specific delineating anatomical structures.
The retroperitoneum or retroperitnium is an anatomical region that includes the peritoneum-covered organs and tissues that make up the posterior wall of the abdominal cavity and the pelvic space - which extends behind to the abdominal cavity.
In women, the rectouterine pouch is the deepest point of the peritoneal cavity. It is posterior to the uterus, and anterior to the rectum. [2] Its anterior boundary is formed by the posterior fornix of the vagina. [1] The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch.
The interior is called the peritoneal cavity, this is the location of all 'intra-peritoneal' organs (disambiguation: retro-peritoneal organs). The most inferior extent of the peritoneum covers the pelvic inlet ; in females, this region of the peritoneum is referred to as the 'broad ligament'.
The structures within the intraperitoneal space are called "intraperitoneal" (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g., the kidneys), and those structures below the intraperitoneal space are called "subperitoneal" or ...
The retropubic space is a surgical landmark that has surgical significance in several gynecological and urological procedures. Access to the space is achieved by separating the rectus abdominis muscle at the mid line, and bluntly dissecting the tissue in the direction of the symphysis pubis, until reaching the peritoneum.
The kidneys are located behind the peritoneum, in the retroperitoneum, outside the abdominal cavity. The viscera are also covered by visceral peritoneum . Between the visceral and parietal peritoneum is the peritoneal cavity , which is a potential space. [ 1 ]
Peritoneal recesses (or peritoneal gutters) are the spaces formed by peritoneum draping over viscera. [1]The term refers mainly to four spaces in the abdominal cavity; the two paracolic gutters and the two paramesenteric gutters.
