Retroperitoneal organs are found behind the peritoneum, between it and the abdominal wall. These include the kidneys, adrenals, and pancreas.
Primarily retroperitoneal:
- urinary
- adrenal glands
- kidneys
- digestive
- esophagus (partially)
- small intestine (partially; for example duedonum with the exception of its first part)
- ascending colon and descending colon
- rectum (part, lower third is extraperitoneal)
The kidneys, pancreas, and parts of the intestines (duodenum, ascending colon, descending colon) are retroperitoneal organs in the abdominal region. These organs are located behind the peritoneum, a membrane that lines the abdominal cavity.

Retroperitoneal structures Structures that lie behind the peritoneum are termed "retroperitoneal". Organs that were once suspended within the abdominal cavity by mesentery but migrated posterior to the peritoneum during the course of embryogenesis to become retroperitoneal are considered to be secondarily retroperitoneal organs.
- Primarily retroperitoneal:
- urinary
- adrenal glands
- kidneys
- ureter
- bladder
- circulatory
- aorta
- inferior vena cava
- digestive
- esophagus (part)
- rectum (part, lower third is extraperitoneal)
- urinary
- Secondarily retroperitoneal:
- the head, neck, and body of the pancreas (but not the tail, which is located in the splenorenal ligament)
- the duodenum, except for the proximal first segment, which is peritoneal
- ascending and descending portions of the colon (but not the transverse or sigmoid)
A useful mnemonic to aid recollection of the abdominal retroperitoneal viscera is SAD PUCKER:
- S = Suprarenal glands (aka the adrenal glands)
- A = Aorta/IVC
- D = Duodenum (second and third segments [some also include the fourth segment] )
- P = Pancreas (tail is intraperitoneal)
- U = Ureters
- C = Colon (only the ascending and descending branches)
- K = Kidneys
- E = Esophagus
- R = Rectum

These organs are wrapped by the peritoneum. Parts of the small intestine (i.e. jejunum and ileum) and parts of the large intestine (i.e. transverse colon and sigmoid colon) are intraperitoneal organs.
Retroperitoneal organs are located behind the peritoneum. The kidneys, pancreas, duodenum, ascending colon, and descending colon are all retroperitoneal organs.
The retroperitoneal organs of the abdominal region are the kidneys, ureter, adrenal glands, and bladder.
The kidneys are retroperitoneal. They are behind the lining of the abdominal pelvic cavity.

Which organ lies within the retroperitoneal space?
The kidneys are the organs that lie within the retroperitoneal space. They are located behind the peritoneum, which is the membrane that lines the abdominal cavity.
What does the term retroperitioneal mean?
The term retroperitoneal refers to the area behind the peritoneum, the membrane lining the abdominal cavity. Organs located in the retroperitoneal space include the kidneys, adrenal glands, and part of the pancreas. These organs are positioned outside the peritoneal cavity and are not covered by the peritoneum.
What is the term for organs that lie within the abdominal cavity but not within the peritoneal cavity?
The term for organs that lie within the abdominal cavity but not within the peritoneal cavity is "retroperitoneal organs." These organs include the kidneys, adrenal glands, pancreas, and parts of the gastrointestinal tract. They are positioned behind the peritoneum, a membrane that lines the abdominal cavity.
Is the spleen retroperitoneal?
No, the gall bladder is an abdominal organ that is contained within the peritoneum. The retroperitoneal organs are the kidneys, adrenal glands and the ureters - they are outside of the peritoneum.
What is located behind the peritoneum?
The retroperitoneal space is located behind the peritoneum. It contains organs such as the kidneys, adrenal glands, pancreas, and parts of the intestines and blood vessels. These organs have a direct relation to the peritoneum but lie outside of it.
Why are the kidneys retroperitoneal?
Organs are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal.
What is the division of the abdominal cavity containing those organs posterior to the peritoneal lining?
The retroperitoneal space contains organs in the abdominal cavity that are behind the peritoneal lining.
Which organ lies within the retroperitoneal space?
The kidneys are the organs that lie within the retroperitoneal space. They are located behind the peritoneum, which is the membrane that lines the abdominal cavity.
What does the term retroperitioneal mean?
The term retroperitoneal refers to the area behind the peritoneum, the membrane lining the abdominal cavity. Organs located in the retroperitoneal space include the kidneys, adrenal glands, and part of the pancreas. These organs are positioned outside the peritoneal cavity and are not covered by the peritoneum.
What is the term for organs that lie within the abdominal cavity but not within the peritoneal cavity?
The term for organs that lie within the abdominal cavity but not within the peritoneal cavity is "retroperitoneal organs." These organs include the kidneys, adrenal glands, pancreas, and parts of the gastrointestinal tract. They are positioned behind the peritoneum, a membrane that lines the abdominal cavity.
Are the kidneys anatomically located ventrally within the abdomen?
The kidneys are located behind (posterior to) the abdominal cavity, in the retroperotoneum.Yes, the kidneys are located outside of the peritoneal cavity. In anatomy, they are referred to as being "retroperitoneal".No. Unlike the other abdominal organs, the kidneys lie behind the peritoneum that lines the abdominal cavity and are thus considered to be retroperitoneal organs.Yes
What is secondarily retro-peritoneal?
Secondarily retroperitoneal refers to organs that were originally intraperitoneal during development but become retroperitoneal in the adult human anatomy. These organs include the kidneys, adrenal glands, pancreas, and ascending/descending colon. They are considered retroperitoneal because they are located behind the peritoneum, the lining of the abdominal cavity.
Is abdominal aorta aintra peritoneal or retroperitoneal?
The abdominal aorta (and inferior vena cava for that matter) is a primary retroperitoneal structure.
What does central retroperitoneal mean?
means anything present behind the peritoneum(The membranous lining of the body cavity especially the abdominal cavity which surrounds most of the organs.
The kidneys lie behind what cavity?
The kidneys lie behind the abdominal cavity, specifically in the retroperitoneal space.
Where is the retro perineal cavity located?
The retroperitoneal cavity is located immediately posterior to the abdominal cavity (behind). It contains the kidneys (and so also the adrenal glands), the pancreas, and the abdominal aorta and vena cava. The walls of the abdominal cavity are covered with a serous membrane, called the peritoneum, as are most internal organs. The fluid in the membrane protects these structures and reduces friction between the organs and the cavity walls as well as between the organs themselves. The retroperitoneal space is separated from the peritoneal space by this layer of membrane covering the anterior organs e.g. liver, stomach, intestines. Both spaces are within the abdominal cavity.
Is the spleen retroperitoneal?
No, the gall bladder is an abdominal organ that is contained within the peritoneum. The retroperitoneal organs are the kidneys, adrenal glands and the ureters - they are outside of the peritoneum.
