What is the retroperitoneal space?

Retroperitoneal space is part of the abdominal cavity that lies behind the delay, a membrane that usually lines the inside of the abdomen. This membrane, which also serves as a tract for many nerves, as well as blood and lymphatic vessels, different organs are supported. The parietal peritoneum is usually attached to the abdominal wall, while a layer called visceral peritoneum is often wrapped around the intraperitoneal organs. Among these layers is also lubricating fluid and blood vessels and nerves.

inside the retroperitoneal space are kidneys, adrenal glands, bladder and ureters. Aorta and lower vessels vena Cava are located in space and also part of the esophagus and rectum. These are called primary retroperitoneal organs, which means that they are usually formed during pregnancy behind a peritted branch and remain there throughout the development. All organs in space usually have some tissue peritone connected kir front or front, although no anatomical structures are generally part of REtroperitoneal space.

Secondary retroperitoneal organs are generally formed in the suspension in the abdominal cavity, but migrate into the retroperitoneal space, as the embryo evolves. In this category, the head, neck and body of the pancreas are usually in this category, as well as most duodenum and ascending and decreasing parts of the large intestine. Different muscles usually form the floor of the retroperitoneal space. These include PSOAS, Quadratus lumborum and part of the abdominal muscles, which are usually covered with different layers, including connective tissue primarily composed of fat.

parts of the large intestine, kidney and suprarenal glands are usually protected by this oily layer of tissue. The retroperitoneal space is also divided into various segments, including the periral space, which is generally defined tissue surrounding the kidneys. There is also an anterior paralenal space that has one layer of gushingthe arc on the one hand and a structure called renal fascia on the other. The rear part is bounded by the renal facade on one side, while the other end is lined with abdominal muscles.

various diseases and other medical diseases are often associated with retroperitoneal space. One condition is called retroperitoneal fibrosis in which fibrous tissue can prevent urinary tracts and blood vessels due to the conditions of the immune system, infection or drugs. Bleeding can also occur in the retroperitoneal space and are sometimes caused by anticoagulant drugs, tumors and aneurism of aorta.
