Urinary Incontinence & Prolapse in Women Flashcards
(41 cards)
Lack of voluntary control over urination or defecation
incontinence
urinary incontinence affects 10-70% of women and peaks around
middle age
Involuntary leakage accompanied by urgency
Need to “rush to the toilet”
Uninhibited bladder contraction
Urge Incontinence (Detrusor overactivity)
Involuntary leakage with effort (coughing, laughing, sneezing, exercise)
Increase in intra-abdominal pressure overcomes sphincter closure
Stress Incontinence
Combination of stress and urge incontinence
Mixed Incontinence
Frequent voids of very small amounts of urine
Overflow Incontinence
what can worsen symptoms of incontinence
COPD/smoking (cough stress)
in office testing for incontinence
- cough stress test
- postvoid residual volume (PVR)
- ultrasound /catheter- inaccurate - urodynamic testing
- cystourethroscopy
In general a PVR less than ____ mL shows adequate emptying
50
Anal and bulbocavernosus
(Osinski) reflex can be used to assess
sacral reflex activity
Q tip test
Measures urethral mobility- there is a problem of urethral support
is a polysynaptic reflex that is useful in testing for spinal shock and gaining information about the state of spinal cord injuries (SCI).
The bulbocavernosus reflex (BCR) or “Osinski reflex”
M1, M2 (80%) and M3 (20%) cholinergic receptors involved in ____________
detrusor contraction
Only M3 cholinergic receptors are responsible for the ________________ detrusor contraction
parasympathetic
detrusor relaxations usually involves which receptor
beta-3 adrenergic receptor
anticholinergic side effects
Dry mouth Constipation. Heartburn Blurry vision Rapid heartbeat (tachycardia) Flushed skin, Urinary retention Impaired memory Confusion. Skin irritation (from oxybutinin patch)
- Relaxes the bladder muscle - β3 agonist
- Can increase the amount of urine bladder can hold
- Increase the amount one is able to urinate at one time
- Side effects Increased blood pressure Common cold symptoms (nasopharyngitis) Urinary tract infection Headache Constipation. Cleared by kidney and liver Interactions with other medications
mirabegron
- Blocks the actions of acetylcholine
- Paralyzes the bladder muscle
- Helpful for people who are non-responders to other medications
- Benefits can last several months
- Repeat injections once or twice a year
- Side effects
Significantly improves symptoms of incontinence
Causes few side effects
May increase urinary tract infections??
Botox
- Alpha antagonist (blocking uptake of norepinephrine at nerve endings)
- It makes the bladder muscle relax
- Makes the smooth muscles at the bladder neck contract
- May be used to treat mixed incontinence — (urge and stress incontinence)
-Side effects
Can include cardiovascular problems (irregular heartbeat)
Dizziness or fainting
Orthostatic hypotension.
Older adults may be especially susceptible to these side effects
Dry mouth
Blurry vision
Constipation
Interactions with many different medications
Imipramine - tricyclic antidepressant - antagonizes everything !!!
- Serotonin and norepinephrine reuptake inhibitor
- Approved to treat depression and anxiety
- Can help the urethral sphincter relax
- Can improve urinary incontinence in some women
- May be helpful for women who have urinary incontinence and depression
- Side effects Nausea Dry mouth Dizziness Constipation Insomnia and fatigue.
Duloxetine- cymbalta
decrease in estrogen affects how the bladder
deterioration of the supportive tissue around the bladder and urethra— weakens the tissue and potentially aggravates stress incotinence
topical estrogen for incontienence
not much scientific evidence
Combination systemic hormone replacement therapy (estrogen plus progestin) not effective
for incontinence
yep
Oral estrogen replacement may worsen/improve incontinence symptoms
