A

comes from an inc. in intrabd pressure and weakened urethral sphincter/pelvic floor muscles (from childbirth or lack of hormones)
-leak a small amount during activities (cough, laugh, sneeze, exercise)

bladder doesnt relax and fill well (from a higher detrussor tone), so it takes less urine to sense stretch and signal the need to pee

what types of food may cause frequency and urgency?

A

caffeine, alcohol, milk, citrus, spices

29
Q

nighttime incontinence without daytime symptoms, consider…

A

LE edema and fluid shifts

- edema in legs during the days goes to the kidneys at night

30
Q

sleep apnea can be associated with what?

A

incontinence (don’t know why)

31
Q

neurogenic bladder: Spastic bladder dysfunction results from …

A

neurologic lesions above the level of the sacral cord

32
Q

neurogenic bladder: Flaccidity of the detrusor muscle is caused by …

A

Flaccidity of the detrusor muscle is caused by disruption of the lower motor neurons of the pelvic nerve

33
Q

what can cause an involuntary contraction of the bladder?

A

when a specific level of stretch is reached

34
Q

5 parts of Dx of incontinence

A
  1. history
  2. pelvic exam
  3. neurologic if appropriate
  4. UA
  5. cystometry
35
Q

pelvic exam for incontinence dx

A
  • check pelvic floor, urethra angle (kinked b/c of prolapse may cause obstructive symptoms).
  • check for atrophic vag (post-menopausal women: stress incontinence)
36
Q

what is cystometry?

A

measures relationship of pressure and volume in bladder, residual volumes, compliance, flow rates and capacity

37
Q

4 kinds of txt for intcontinence

A
  1. behavioral
  2. exercises/devices
  3. medical
  4. surgery
38
Q

behavioral txt for all types of incontinence.

A

Diet modification, bedtime fluid restriction

39
Q

behavioral txt for urge incontinence

A

timed voiding with increasing intervoiding times results in increased bladder capacity

40
Q

4 kinds of exercises/devices for incontinence txt

A

Kegel exercises
Vaginal cones
Pessaries
InterStim device stimulates pudendal nerve, has 80% efficacy

41
Q

what does a vaginal cone do?

A

improves strength and tone

42
Q

what are pessaries for?

A

pushes on neck of bladder. provides support that is no longer there
- for pelvic floor collapse

43
Q

what is the main txt type for OAB and urge? how does it work? what are the preferred agents?

A

medical - anticholinergics to decrease detrussor muscle tone. (trospium/Sanctura for the least ADRs )

44
Q

what drug can be prescribed for stress incontinence? how does it work?

A

SNRI- duloxetine/ Cymbalta : blocks the reuptake of serotonin and NE in the spinal cord

45
Q

what are the concerns with cymbalta?

A

suicide in younger patients taking it

46
Q

surgery is mostly an option for what type of incontinence?

A

stress

47
Q

what are two surgery options for stress incontinence?

A

burch procedure and suburethral slings

48
Q

what is the burch procedure? when is it used?

A

an invasive urethropexy: neck of the bladder is suspended from nearby ligaments with sutures.
-when the bladder or urethra has fallen out of its normal position

49
Q

what is the most popular suburethral sling?

A

“tension free vaginal tape”

50
Q

if its a mechanical problem, its likely a _____ fix

A

mechanical

51
Q

tension free urethral sling (vaginal tape) will not help if ______ _____

A

prolapsed uterus

52
Q

what is intradetrusor botox injection used for?

A

OAB if neurogenic bladder from spinal cord injury or MS

53
Q

what is neuromodulation for OAB?

A

stimulation of S3 afferents with implanted electrodes- thought to reprogram central voiding reflex

54
Q

what are the two types of enuresis (bedwetting) ?

A

primary and secondary

55
Q

below age ___, enuresis is not really a uncommon or a concern

A

7

56
Q

what is primary vs secondary enuresis

A

3

58
Q

enuresis: Alertness should be maintained for symptoms of common underlying problems such what three things?

A

constipation, stress, cystitis/UTI

59
Q

PE for enuresis

A
  1. abd and pelvic exams
  2. neuro exam of lower extremities
  3. assessment of the “anal wink”

60
Q

Dx of enuresis

A

UA for UTI, otherwise behavioral assessment, then imaging down the line

61
Q

Txt of enuresis (3 parts)

A
  1. motivational therapy (sticker chart)
  2. enurersis alarms (detect wetness and wake the pt)
  3. desmopressin (ADH hormone) - we should naturally produce more of this at night
62
Q

conditions that may cause or mimic OAB( weeds)

A
  • Bladder detrusor muscle may contact inappropriately due to nerve damage/ infection, surgery, tumors, Parkinson’s, MS, stroke
  • UTIs
  • Polyuria
