Kidney, Ureter, Bladder Flashcards
Location of the kidney
T12 - L3
3 coverings of the kidney
- perirenal fat
- renal fascia/gerota
- pararenal fat
3 structures that enter the renal hilum
- renal vein - anterior
- renal artery
- renal pelvis - posterior
Landmarks of Left kidney
superior pole - 11th rib
hilum - L1
inferior pole - L3
Landmark of Right kidney
hilum - L1 and L2
Blood supply of kidney
renal artery from aorta L2
venous supply of kidney
renal vein from IVC
nerve supply of kidney
renal sympathetic plexus
lymph drainage of kidney
lateral aortic lymph nodes
Renal transplant
- renal artery anastomosed to internal iliac artery
2. renal vein anastomosed to external iliac vein
Weight of adrenal gland
4 grams
characteristic of right adrenal gland
triangular in shape
anteromedial - IVC
anterolateral - liver
posterior - diaphragm
characteristic of left adrenal gland
crescent in shape
anterior - stomach, splleen, pancreas
posterior - diaphragm
embryonic origin of adrenal gland
- cortex - mesoderm
2. medulla - neural crest
blood supply of adrenal medulla
- superior from inferio phrenic artery
- middle from abdominal aorta
- inferior from renal artery
venous drainage of adrenal medulla
- right adrenal vein drains to IVC
2. left adrenal vein drains to left renal vein to IVC
areas of ureteric constrictions
- renal pelvis joins the ureter
- crosses the pelvic brim and external iliac artery
- pierces the bladdder wall
blood supply of ureter
- upper - renal artery
- middle - gonadal artery
- lower - superior vesical artery
lymph node drainage of ureter
- lateral aortic
2. iliac nodes
nerve supply of ureter
- renal plexus
- testicular/ovarian plexus
- hypogastric plexus
Dermatome level of Renal Colic
T11 - L2
blood supply of the urinary bladder
- superior vesical
2. inferior vesical from internal iliac
venous drainage of urinary bladder
venous plexus to internal iliac
false ligaments of the urinary bladder
- medial umbilical ligament
2. median umbilical ligament
true ligaments of the urinary bladder
- pubovesical/ puboprostatic
2. recto vesical
nerve supply of the urinary bladder
- smypathetic - upper lumbar nerves through hypogastric plexus
- parasympathetic - pelvic splanchnic S2 - S4
Lymph node drainage of urinary bladdder
internal and external iliac nodes
function of parasympathetic nerve of urinary bladder
contraction of detrussor muscle and relaxes the sphincter vesicae
emptying of urinary bladder
function of sympathetic nerve of urinary bladder
inhibit contraction of detrussor muscle
stimulate closure of sphincter vesicae
What are the outcomes of URETERIC BUD/ METANEPHRIC DIVERTICULUM OR DUCT
- ureter
- renal pelvis
- renal calices
- collecting tubules
What are the outcomes of METANEPHRIC TUBULES
- nephron
Divisions of urogenital sinus
- cranial vesical part
- middle pelvic part
- caudal phallic part
Fate of Vesical part of urogenital sinus
urinary bladder
Fate of pelvic part of urogenital sinus
urethra in the bladder neck
prostatic and membranous parts in males and entire part in females plus lower part of vagina
fate of phallic part of urogenital sinus
genital tubercle
