Kidneys, ureters, bladder, urethra Kidneys- retroperitoneal, bean-shaped Oblique orientation, paravertebral gutters along
posterior abdominal wall One on each side of spine at the
level of T12 – L4 Surrounded by perirenal fat, and Gerota’s fascia Composed of
outer cortex- functional subunit- nephrons- filter urine inner renal medulla- pyramids, Loops of Henle
Mass on CT recon ofHorseshoe Kidney
Retroperitoneal, paired, suprarenal, y shaped Rt adrenal- posterior to IVC, medial to Rt
hepatic lobe, lateral to Rt crus of diaphragm. Lt adrenal- in “triangle” of the aorta,
pancreatic tail, and Lt kidney- borders Lt crus of diaphragm
Outer cortex- produce steroids Corticosteroids
glucocorticoids, mineralocorticoids and androgens Inner medulla
Hormones Epinephrine and norepinephrine- fight or flight
NeuroblastomaOf Lt adrenal gland
Adrenal Hemorrhage
Neuroblastoma
Stomach- food reservoir and early digestion Located under Lt dome of diaphragm Superior portion- joins esophagus at cardiac
orifice (cardiac sphincter) Boder- lesser and greater curvature Inferior portion- pyloric antrum -> duodenum Anterior surface- contact with diaphragm,
anterio abdominal wall and Lt lobe of liver Lining of stomach = rugae Gastric juices= mucus, hydrochloric acid,
intrinsic factor and pepsinogen and lipase Very vascular organ
CT scan of chest & upper abdomen (coronal section); herniation of stomach & splenic flexure of colon, along with collapse of lung and mediastinal shifting
Small bowel between pylorus and ileocecal valve
6-7 meters in length Duodenum
Pylorus- head of panc- retroperitoneal 4 portions
First- superior-duodenal bulb Second- descend- ampulla of Vater Third- horizontal- L3- ant to SVC, AO Fourth- ascending- Lt of AO at L2 meets with Jejunum
jejunum– duodenojejunal flexure ligament of Treitz- suspensory lig-around celiac axis Entry of small bowel into peritoneal cavity Lt upper abdomen/ umbilical region- absorption occurs- folds??
Ileum Longest portion, RL abdomen- terminate at ileocecal valve-
CECUM Often this is the site of intussusception / inflammation and
WHAT?
Intestines
herniaIntussesseption
Inferior to stomach and liver Larger diameter, haustra and bands called
taenia coli The appendix attaches to posteromedial
surface of cecum Ascending-
retroperitoneal, cecum to liver- hepatic flexure Transverse
Peritoneal, horizontal, toward spleen, splenic flexure Descending
Retroperitoneal, Lt lat abd to sigmoid Sigmoid
Chains along branches of arteries of intestine and AO
Small, oblong, soft and difficult to visualize –unless ABNORMAL
Enlarged= greater than 1 cm in short axis and 2 cm in long axis.
Abdominoaortic nodal groups- surround AO/IVC Visceral –drain adjacent organs Lymph drains from abdominal cavity into
lumbar trunk, and intestinal in to intestinal trunk and both trunks join the thoracic duct and then the venous system
PTLD????
Diaphragm Quadratus lumborum
Lg portion of posterior abdominal wall Iliac crest- inferior 12th rib
Psoas Lateral surpaces of lumbar vertebrae Insert into greater trochanter of femur
Rectus abdominis Anterior surface of abd/pelvis
Linea alba Xiphoid- symphysis pubis- midline and
interlacing
