Anatomy, Abdomen and Pelvis, Retroperitoneum

Excerpt

The retroperitoneum is an anatomical space located behind the abdominal or peritoneal cavity. Abdominal organs that are not suspended by the mesentery and lie between the abdominal wall and parietal peritoneum are said to lie within the retroperitoneum. Several individual spaces make up the retroperitoneum. These spaces are the anterior pararenal space, posterior pararenal space, and the perirenal space. Each of these spaces contains parts of various organs and structures. These structures include organs that contribute to several systems in the body, including the urinary, adrenal, circulatory, gastrointestinal, and endocrine systems. This article will discuss the structure, function, embryology, and anatomy of the retroperitoneum, and will also include discussion of its clinical significance and specific surgical considerations.
