summary

2. Retroperitoneal space:
 between the peritoneum and the posterior
parietal wall of the abdominal cavity
 from the diaphragm to the pelvic floor

3.  Superiorly- 12th thoracic vertebra, lateral
lumbocostal arch and diaphragm
 Inferiorly- base of the sacrum, iliac crest,
and iliolumbar ligament, pelvic levator
muscles.
 Anteriorly- posterior parietal peritoneum
 Posteriorly- fascia overlying the quadratus
lumborum and the psoas major muscles,
vertebral column, tendinous portion of
tranverse abdominis.

5.  Urinary: adrenal glands
kidneys
ureter
 Cirulatory: abdominal aorta
inferior vena cava
 Digestive: oesophagus (thoracic part)
rectum (part of middle third and
lower third)
pancreas(head, neck and body)
duodenum (except the first part)
ascending and descending colon

6.  Suprarenal (adrenal) glands
 Aorta/IVC
 Duodenum
 Pancreas
 Ureters
 Colon
 Kidneys
 Esophagus
 Rectum

7.  It is divided into three spaces by the
anterior renal fascia (Gerotas’s) and
posterior renal fascia (Zuckerkandl) fascia
 The three spaces are:
Anterior pararenal space
Perirenal space
Posterior pararenal space

11.  Superior – to bare area of liver and is
contiguous with the mediastinum
 Medial – at the level of renal hilum
 Lateral – Anterior renal fascia and posterior
renal fascia fuse to form lateral conal plane
 Inferior – ARF and PRF fuse around 8cm
below kidney

12.  Retromesentric plane
 Retrorenal plane
 Lateral conal plane

13.  between anterior pararenal and perirenal
spaces contigous across the midline and
laterally with the retrorenal and lateral
conal space

14.  between the perirenal and posterior
pararenal space

15.  Combined fascial plane that continous into
pelvis anterolateral to psoas muscle
 Allows pathway to pelvis
 Trifurcation of 3 planes
