Q

What is a stag-horn calculi indicative of?

A

Stag-horn calculi are larger renal stones that can extend from the renal pelvis into the calyces and quickly lead to obstruction. These are made from struvite, also known as ammonium magnesium phosphate). Infection from Proteus species can predispose to struvite stone formation and hence, the formation of a stag-horn calculus as they metabolise urea into ammonia.

61
Q

What is the pathophysiology of BPH?

A

BPH is characterised by the nodular overgrowth of prostatic tissue, predominantly in the transition zone. This growth impinges on the prostatic urethra, causing dynamic and static obstruction, leading to urinary symptoms.

62
Q

A

Low or high pressure and by the presence of detrusor activity

63
Q

What can cause Chronic Urinary retention?

A
  • Benign prostatic hyperplasia (most common)
  • Prostate cancer
  • Certain medications such as antihistamines, anticholinergics, or antispasmodics
  • Congenital conditions such as posterior urethral valves
64
Q

What are the management strategies for Chronic Urinary Retention?

A
  • Alleviate the obstruction (often with catheterization)
  • Address the underlying cause
  • Pt may require IV fluids to manage post-obstructive diuresis
65
Q

What complications can result from chronic obstructive diuresis?

A
  • Post-obstructive diuresis
  • Chronic Kidney disease
  • Hydronephrosis
  • Bladder Diverticula
66
Q

When does post-obstructive diuresis occur?

A
  • Occurs when there is >200ml/hr for two consecutive hours or
  • Production of >3L of urine in 24 hours
67
Q

Why does post-obstructive diuresis occur?

A
  • Due to hydronephrosis there is loss of medullary concentration gradient in nephrons.

Results in massive loss of water and salt through polyuria.

In these patients there is a severe risk of hypovolaemia and hyponatraemia/other electrolyte imbalances.

68
Q

How do you manage post obstruction diuresis?

A

Urine osmolarities should be taken as this will determine management.

  • Iso-osmolar urine indicate the kidneys do not need to concentrate the urine and is consistent with physiological diuresis and it generally self-limiting.
  • Hyper-osmolarity indicates the kidneys are concentrating urine so post-obstructive diuresis has, or is resolving.
  • Hypo-osmolarity indicates salt wasting and the inability for the kidneys to concentrate urine. This is pathological and patients should have fluids replaced like for like.
69
Q

Which of the urethral sphincters is under voluntary control and what is its innervation?

A

External Urethral sphincer is under voluntary control through the pudendal nerve

70
Q

What are the investigations for Erectile Dysfunction?

A

QRISK3
Free testosterone (should be measured in the morning between 9am and 11am)
- If free testosterone is low or borderline then should be repeated along with follicle-stimulating hormone, luteinizing hormone and prolactin levels.

Q

What is the next appropriate treatment for a man with Erectile dysfunction were Sildenafil is contraindicated?

A
