What substance is most likely causing the pain in this patient?

A
  • renal colic caused by renal stones

- most renal stones are made up of calcium oxalate

17
Q

Rampiril

A

ACE inhibitor

18

majority of renal phosphate reabsorption occurs in the ….

A

PROXIMAL CONVOLUTED TUBULE

20
Q

which cells detect changes in salt concentrations and adapts the glomerular filtration rate accordingly?

A
  • macula densa
21
Q

Describe where principal cells are located and their role?

A
  • located in DCT

- have ADH and aldosterone receptors

22
Q

which cells are located in DCT and have aldosterone and ADH receptors?

A
  • principal cells
23
Q

Role of juxtaglomerular cells?

A
  • smooth muscle cells
  • mainly lcoated in afferent arteriole walls
  • baroreceptors
  • detect BP changes
  • secrete RENIN
24
Q

mechanisms a patient in hypovolemic shock may use to maintain BP

A
  • increase heart rate
  • peripheral vasoconstriction
  • arterioles are sites of highest resistance in CV system
25
Q

29 y/o male, polyuria, polydipsia, in hospital previously for a head injury.

water deprivation test was done.

pituitary MRI showed thickened pituitary stalk.

patient most likely has?

A
  • diabetes insipidus
26
Q

y wave on JVP

A

ventricular filling

emptying of right atrium

27
Q

arterial baroreceptors located

A

carotid sinus and aortic arch

28
Q

bladder recieves parasympathetic innervation from

A
  • pelvic splanchnic nerves
29
Q

what recieves venous drainage from the bladder and prostate?

A
  • vesicoprostatic venous plexus
30
Q

A 25-year-old man is injured in a road traffic accident. His right tibia is fractured and is managed by fasciotomies and application of an external fixator. Over the next 48 hours his serum creatinine rises and urine is sent for microscopy, muddy brown casts are identified. What is the most likely underlying diagnosis?

A

acute tubular necrosis.

31
Q

acute interstitial nephritis

A
  • usually occurs aar of drug toxicity

- no muddy brown casts

A 63-year-old male presents with several episodes of haematuria. He suffers from COPD secondary to long term smoking. What is the most likely underlying cause?

A

transitional cell carcinoma of bladder strongly linked to smoking/

33
Q

Alport syndrome

A
  • X linked dominant
  • defect in type 4 collagen gene
  • abnormal glomerular basement membrane
34
Q

42 y/o female with diabetes. has been started on metformin. worried about how diabetes will affect kidneys longterm.

by which mechanism does the most damage to kidneys occur?

A
  1. non-enzymatic glycosylation of vascular membrane
  2. in large and medium vessels leads to atherosclerosis
  3. NEG in small vessels —-> hyaline arteriosclerosis
  4. sclerosis of renal efferent arteriole of glomerulus
  5. leads to nephropathy
35
Q

bladder receives sympathetic innervation from the?

A

superior and inferior hypogastric plexuses

36
Q

horseshoe kidneys become trapped under what which prevents their anterior ascent

A

inferior mesenteric artery

37

A
  • cholecystitis

- leads to post hepatic jaundice aar of biliary obstruction

39
Q

A
  • afferent arteriole constriction
