Q

What is urge incontinence

A

Characterized by a sudden, intense urge to void followed by involuntary urine leakage. It is often caused by overactivity of the detrusor muscle, which may be triggered by infections, bladder stones, or neurological conditions like stroke or multiple sclerosis.

70
Q

What is stress incontinence

A

This occurs when there is leakage during activities that increase intra-abdominal pressure, such as coughing, sneezing, or exercising. More common in women

71
Q

What is outflow incontinence

A

This type involves leakage due to an overfilled bladder, often caused by mechanical obstruction

72
Q

What is functional incontinence

A

This is when an individual is not able to reach a toilet in time

73
Q

What causes an urge incontinence

A

Overactivity of the bladder wall as a result of UTI, MS and bladder stones

74
Q

What causes stress incontinence

A

Weak pelvic floor

75
Q

What causes overflow incontinence

A

This is caused by a mechanical obstruction e.g. BPH

76
Q

What is the management of urinary incontinence

A
  1. Behavioral management: Pads, and exercises
  2. Medical management: With anticholinergic drugs
