35
Q

What two vessels are responsible for the compression in Anatomical Nutcracker?

A

Q

What is the overall innervation of the kidney?

A

Renal plexus

40
Q

The renal plexus is formed by fibers from what locations?

A

Celiac plexus, aortic plexus, direct branches from the thoracic and lumbar splanchnic nerves

Q

What are the functions of the fat around the kidneys?

A

Protection, insulation, support (attachment to the posterior wall)

42
Q

What are the layers covering the kidneys?

A

Renal capsule (innermost), perinephric fat, renal fascia, paranephric fat (outermost)

43
Q

What is the membranous layer of extraperitoneal tissue which splits into anterior and posterior layers to enclose the kidney?

A

Q

What are the risk factors for renal calculi?

A

Being male, low fluid intake/dehydration, southeastern U.S.A.

47
Q

What is the pain pathway of renal calculi?

A

Dull ache in the kidney followed by severe pain when they enter the ureter

48
Q

What happens if renal calculi become lodged in the ureter?

A

Restriction of urinary flow

49
Q

What is a possible treatment to break up renal calculi?

A

Q

What is the nickname for nephroptosis?

A

“Floating Kidney”

52
Q

What is nephroptosis?

A

53
Q

Where can the kidney descend to during nephroptosis?

A
