1

what layers surround the kidneys

perirenal fat (around)
renal fascia (extraperitoneal fascia)
pararenal fat (along side)

2

at what vertebral levels are the kidneys

t12 - L3

3

which kidney is lower

right

4

which kidney is longer

left

5

what are the anterior relations of the right kidney

IVC, duodenum, liver, colic flexure, suprarenal gland

6

what are the anterior relations of the left kidney

pancreas, spleen, stomach, colic flexure, small intestine

7

what ribs does the kidney overlie

10, 11, 12

8

why do the kidneys move with respiration

they lie on the diaphragm

9

what abdominal muscles do they kidneys lie on

QL, TA, psoas major

10

what is the renal column

the extension of cortex between the pyramids

11

what are the renal papillae

the part of the medulla that projects into the minor calyx

12

where in the kidney are the nephrons

renal pyramids

13

what vertebral level are the renal arteries

L1- left
L2- right
behind the renal veins
there may be extrahilar arteries branching from the aorta

14

where does lymph from the kidney go to

lumbar nodes

15

what structures are in the renal hilum, from anterior to posterior

vein
artery
pelvis

16

why is the right renal vein short

the IVC is to the right of the midline
this makes surgery difficult

17

what does the renal artery divide into

five segmental arteries that enter at the hilum

18

what arteries arise from each segmental artery

lobar arteries, one for each pyramid

19

what arteries arise from the lobar arteries

interlobar arteries

20

what are the arcuate arteries

branches of the interlobular arteries which arch over the base of the pyramids
these give off interlobular arteries

21

what do the afferent glomerular arterioles supply

renal corpuscle
arise from the branches of the interlobular arteries

22

what is the kidney nerve supply

T12 and L1

23

where is kidney pain referred to

back and lumbar regions, loin and groin

nausea and emesis may be associated due to vagal afferents

24

where is the ureter

posterior abdo wall
23-30 cm long

25

where are the narrowings of the ureter

pelvic ureteric junction
crossing the pelvic brim
passing into the bladder

26

what do the ureters cross

ant to psoas major
anterior to lumbar plexus
bifurcation of the common iliac artery
overlies the lumbar transverse process
runs medial to the sacral iliac joints
passes medial to the branches of the internal iliac on the lateral pelvic wall and floor

27

what does the pelvic ureter cross in the male

between the vas and seminal vesicle

28

where does the pelvic ureter pass in the female

posterior to ovary
inf to uterine artery
passes cervix and lateral fornix of vagina

29

where does lymph from the ureter pass

para aortic and iliac nodes

30

what is the blood supply of the ureter

Aorta
Renal
Gonadal
Common and internal iliac
Uterine, vaginal
Vesical
