Q

Give 4 functions of the lower urinary tract.

A
  1. Storage of urine.
  2. Converts the continuous process of excretion to an intermittent, controlled and volitional process.
  3. Prevents leakage of stored urine.
  4. Allows rapid, low pressure voiding.

Q

Describe the physiology of micturition.

A

The bladder fills and stretch receptors are stimulated. Afferent impulses stimulate parasympathetic action of detrusor muscle; it contracts. The urethral sphincters relax; this is mediated by inhibition of the neurones to them. The PAG is stimulated.

IgA gets glycosylated (sugar sticks to it) => when moves through kidney, gets deposited => inflammation and scarring (nephritis)

263
Q

Describe the pathophysiology behind nephrotic syndrome.

A

Podocytes or basement membrane aren’t working properly and so huge amounts of protein leaks into the bowman’s capsule and is excreted in the urine.

264
Q

A 50 y/o M presents with haematuria. On examination he has HTN, increased serum Cr and urea, proteinuria and bilateral palpable costo-vertebral angle masses. You take a family history and find out that his dad died of a sub-arachnoid haemorrhage. What is the most likely diagnosis?

A

ADPKD.

  • Normally people present around 50 y/o.
  • Raised creatinine and urea indicate a kidney problem.
  • The kidneys can be HUGE in ADPKD hence the palpable masses.
  • Intracranial haemorrhages are an extra-renal manifestation of ADPKD.
265
Q

A

Normally present around 50 y/o.

Cysts increase in size with advancing age.

266

A

Cysts increase in size and cause renal enlargement. Often the kidney’s can be HUGE!

267

285
Q

What CCB can be used to treat renal stones?

A
