Q

Why is the left renal vein longer than the right renal vein?

A

It passes anterior to aorta to drain into the IVC

17
Q

State the lymphatic drainage for the kidneys

A

Lumbar nodes

18
Q

Outline the blood supply to the ureters

A 
Renal artery
Abdominal aorta
Common iliac artery
Internal iliac artery
Vesicular artery
19
Q

State the lymphatic drainage for the ureters

A

Lumbar nodes

Iliac nodes

20
Q

An infrarenal abdominal aortic aneurysm involves the renal arteries. True/ False?

A

False

The proximal renal artery is occluded in suprarenal aneurysm

21
Q

List common anatomical variants of the kidney

A 
Bifurcated renal pelvis
Bifurd/ duplicated ureters
Retrocaval ureter (behind IVC)
No seperation
Ectopic kidney
Solitary kidney
22
Q

Outline the basic structure of the kidney from outer to inner layer

A 
Renal capsule
Renal cortex
Renal medulla
--> Renal pyramids
--> Nephrons
23
Q

Nephrons are contained within what structure of the kidney?

A

Renal pyramids

24
Q

Outline the structure of the nephron in order of blood flow

A 
Glomerulus
Proximal convulated tubule
Loop of Henle
Distal convulated tubule
Collecting duct
25
Q

What is the function of the glomerulus?

A

Ultrafiltration of blood from renal artery branches

26
Q

Outline the collecting duct system in order of urine flow

A

Minor calyx
Major calyx
Renal pelvis
Ureter

27
Q

The structures of the collecting duct system increase/decrease in diameter until pelviureteric junction.

A

Increase

28
Q

List anatomical sites of ureteric constriction

A

Pelviureteric junction
Ureter crosses anterior aspect of common iliac artery
Ureteric orifice

29
Q

State the two types of ureteric obstruction and give examples

A

INTERNAL: impacted renal calculi from urine calcium salts, blood clot
EXTERNAL: expanding mass e.g. tumour

30
Q

Describe the response of the ureter in obstruction

A

Increase in peristalsis proximal to obstruction to try remove it - comes in waves causing colicky pain

31
Q

List the consequence of ureteric obstruction

A

Urine production continues until UT pressure > pressure favouring filtration at glomerulus –> RENAL FAILURE

32
Q

What is renal failure?

A

Failure to adequately filter blood into urine

33
Q

What is hydronephrosis?

A

Water inside kidney

34
Q

What is the pathogenesis of hydronephrosis?

A

Urine back pressure into calyces compresses nephrons in medullary pyramids causing renal failure
