1 Definition

Retroperitoneal is a term used to discribe structures and organs which are just anteriorly coverd by peritoneum.

2 Classification

The classification is given by the different development of the organs within the abdominal cavity.

2.1 Primarily retroperitoneal

Primarily retroperitoneal organs develop and remain anteriorly covered by peritoneum. Examples of primarily retroperitoneal organs are kidney and ureter.

2.2 Secondarily retroperitoneal

Secondarily retroperitoneal organs develop first intraperitoneal but they become retroperitoneal during emryogenesis. Examples of secondarily retroperitoneal organs are ascending and descending colon or pancreas.

3 Mnemonic

  • S = Suprarenal glands
  • A = Aorta and Inferior vena cava
  • D = Duodenum
  • P = Pancreas (except tail of pancreas)
  • U = Ureter
  • C = Colon (ascending and descending part)
  • K= Kidney
