Alduzosin hydrocholrise, dozazosin, tamsulosin, prazosin :

A

Alpha blockers

34
Q

MoA of Tamsulosin:

41
Q

What should you consider in any patient presenting with voiding difficulty, particularly those with incontinence

A

Detrusor failure or underactive detrusor function. Incontinence may be overflow.

42
Q

Incontinence =

A

A storage symptom. Any involuntary loss of urine

43
Q

2 ways incontinence can be an issue:

  • Social

- Hygiene

44
Q

Types of incontinence:

A

Stress
Urge
Overflow
Mixed

45
Q

Stress incontinence =

A

Leakage of urine due to extra abdominal pressure (coughing, sneezing, laughing). Usually due to problem with sphincter.

46
Q

Urge incontinence =

A

Sudden urge and intense need to pass urine. Usually due to bladder spasms

47
Q

Mixed incontinence =

A

Stress and urge

48
Q
