|
has some questions on it. check it out she might take practice questions from here (she wrote this site)
|
|
Is incontinence a normal part of aging?
|
no
|
|
Definition
|
leakage of urine THAT INTERFERES WITH QUALITY OF LIFE OR HEALTH.
it is leakage of any amount of urine. doesn't matter how many pads you wear. |
|
most common reason in med to get it
|
after surgery for prostate CA or BPH
|
|
External sphincter relationship with passive continence
|
not involved.
|
|
Symp innervation of lower urinary tract
|
Hypogastric nerves
T10-L2 |
|
Parasymp inn of lower urinary tract
|
pelvic nerves
S2-4 |
|
Somatic inn of lower urinary tract
|
Pudendal nerves
Includes external urethral sphincter and muscles of the pelvic floor |
|
Innervation at bladder neck and top of urethra
|
hypogastric nerve.
Symp lets you hold urine in. Para lets you urinate. (beta receptors) |
|
Bladder dysfunction causes of incontinence
|
Urge incontinence
Either due to detrusor overactivty (neurogenic or nonneurogenic origin) or poor compliance (gradual rise in pressure) Overflow incontinence - incomplete emptying |
|
Urethral dysfunction causes of incontinence
|
leakage with activity.
Stress incontinence due to anatomic issues (mobility of bladder neck) or intrinsic sphincter deficiency |
|
DIAPPERS
|
reversible causes of incontinence
Delirium Infection Atrophic vaginits Pharmacologic (e.g. narcotics) Psychological Excessive urine prod Restricted mobility - can't get to bathroom Stool impaction |
|
Constant incontinence causes
|
congenital ectopic fistula
iatrogenic vesicovaginal fistula |
|
why smoking is a risk factor
|
more coughing, more damage to pelvic floor.
|
|
is low fluid intake a risk factor?
|
yes - high [] urine is bad.
|
|
estrogen depletion can cause...
|
atrophic vaginitis.
|
|
Types of incontinence
|
stress, urge, overflow, mixed
|
|
Stress incontinence pts are...
|
rarely wet at night.
leakage with coughing, laughing, sneezing, etc. |
|
Stress incontinence due to...
|
abdominal pressure poorly transmitted to proximal urethra.
loss of support from pelvic floor muscles. or intrinsic sphincter deficiency - due to surgery, alpha blockers, hormones. |
|
Urge incontinence
|
can be triggered with water cues.
there is a demand to go immediately and you have no choice. bladder pressure gets really high and exceeds sphincter pressure. Due to detrusor overactivity or hyperreflexia. |
|
CMG (cystometrogram) in overactive bladder
|
high pressures relieved when urination begins.
|
|
"overactive bladder"
|
created by drug companies - not associated with any leakage.
|
|
CMG in poor compliance bladder
|
the CMG just linearly increases
|
|
Detrusor underactivity
|
can lead to incontinence
|
|
Causes of extreme bladder volumes
|
rare in women - prolapse or post suspension
men - prostate disease or urethral stricture |
|
when to consider urethral strictures
|
young pts.
due to STIs or trauma to urethra (often falling on bar of bicycle) |
|
Dysfunctional eliminators
|
they dont relax pelvic floor when they void so bladder has to squeeze very very hard but tires out with time.
bowel movements every 7-12 days |
|
provacative stress test
|
checking to see if the pt leaks with an increase in abdominal pressure.
|
|
when to do urodynamics
|
pts who don't respond to medical therapy.
it is to assess bladder storage (overactivity and urge), outlet (abnormal bladder neck and stress) and emptying (overflow). |
|
when to do pad test
|
when history doesn't match the physical (e.g. bad history but no leaking on provocation)
|
|
Tx of urge incontinence - ways to deal with it
|
absorbent products
external collection devices for males (condom with a bag on the end) penile clamps indwelling catheters - which exacerbates the bladder problem bc the bladder wants to contract to get the foreign object out) |
|
Conservative ways of treating urge incontinence
|
timed voiding is the best thing.
change fluid intake pelvic floor exercises... |
|
Anticholinergic SEs
|
dry mouth
flushing constipation (and stool impaction is a cause of urge incontinence so this can make things worse) urinary retention CONTRAIND IN NARROW ANGLE GLAUCOMA (most pts have open angle) |
|
rx of poor compliance
|
complete bladder emptying with clean intermittent cath or indwelling cath
anticholinergics alpha antag. |
|
Rx of stress incontinence
|
pelvic floor exercises
alpha agonists estrogen tricyclic antidepressants |
|
Rx of urge incontinence - surgical
|
treat the bladder outlet obstruction (e.g. TURP)
botulinum toxin nerve stim |
|
Tx of overflow - surgical
|
releive the obstruction
empty bladder (CIC or timed voiding) |
|
PV sling
|
pulls bladder neck up - good for anatomy stress urge incontinence
an alternative to this is injecting collagen |
|
Follow-up in these pts
|
check post-void residual if previously abnormal.
anticholinergics determine response to treatment. |
