  2. Urge incontinence
  3. Mixed incontinence
  4. Detrusor disinhibition incontinence
  5. Functional incontinence
90
Q

Explain urge incontinence

A

Urge incontinence is caused by an involuntary detrusor contractions which cause an urgent need to void.

After a variable latency period, the contractions exceed bladder outlet resistance (normally produced by the intenal sphincter), resulting in incontinence.

91
Q

Explain the mechanism of how detrussor disinhibition results in incontinence.

A

Spontanous triggering of the spinal reflex voiding mechanism when bladder reaches a threshold volume and there is inadequate inhibition of bladder contractions by the CNS;

Urine loss may occur with or without warning !

92
Q

Explain the machanism of stress incontinence.

A

Leakage caused by an increase in intra-abdominal pressure, as produced by a cough, sneeze, laughing, standing up, or heavy lifting.

Also called sphincter incompetence.

93
Q

Explain what DHIC means and what overflow is ?

A
  • DHIC - Detrusor Hyperactivity with Impaired Contractility => despite an overreactive bladder, detrusor contractions are ineffective, resulting in bladder distention and overflow incontinence;
  • Overflow - due to urinary retention, pressure in the bladder exceeds outlet (sphincter) resistance causing leakage until the bladder pressure drops below the outlet resistance.
94
Q

Explain functional and mixed incontinence.

A
  1. Mixed incontinence : incontinecne form multiple etiologies, most commonly stress and urge;
  2. Functional incontinence : incontinence despite a normaly functioning bladder due to the inability to reach a toilet in time;
95
