Superior thickening of the quadratus lumborum fascia

7
Q

Paranephric fat

A

Large amount of fat found only posterior to the kidney

8
Q

Blood supply to Adrenal Glands

A

Superior Suprarenal Artery- from inferior phrenic

Middle Suprarenal Artery- from Aorta

Inferior Suprarenal Artery- from Renal

9
Q

Left Renal Vein

A

Receives drainage from the left testicular/ovarian and left superior suprarenal veins

10
Q

Subcostal Nerve

A

Level = T12

Distribution= Skin and muscles of anterolateral abdominal wall

Course= Passes beneath lateral arcuate ligament and courses laterally

11
Q

Iliohypogastric Nerve

A

L= L1

D= Skin of upper inguinal and suprapubic region; internal oblique and transversus abdominus muscles

C=Course inferolaterally anterior to quadratus lumborum

12

Course inferolaterally anterior to quadratus lumborum

13
Q

Damaged on lumbar approach to kindey

A

Subcostal, ilioinguinal, and iliohypogastric nerves

14
Q

Genitofemoral Nerve

A

L= L1, L2

D= Genital branch; motor to cremaster
Femoral branch; skin of medial thigh

*Pierces the psoas, courses inferiorly on the ANTERIOR PSOAS, abd separates

18
Q

Lumbosacral Trunk

A

L= L4-L5

D= Joins sacral plexus

19
Q

Illiopsoas Test

A

Patient flexes thigh against resistance

Pain? => Inflammation involving the psoas
-Could be appendicitis

20
Q

Three Sites of Ureter Constriction

A
  1. Uretopelvic Jnxn
  2. Pelvic Inlet (b/w external and internal illiac arteries)
  3. Entrance to bladder
