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.
