1
Q

A
  • urinary incontinence is not a normal change with aging

- it results from some age related changes, genitourinary pathology, comorbid conditions, and environmental obstacles

Q

DRIPP

A
  • reversible causes
    D = delirium
    R = restricted mobility
    I = infection, inflammation, impaction of stool
    P = polyruia secondary to d.m., caffeien, volume overload
    P = pharmaceuticals (diuretics, atuonomic agents, psychiatric drugs)

Q

Urge incontinence

A
  • patients experience sudden strong urge to urinate
  • this happens at frequent intervals
  • the DETRUSOR muscle responds to small urinary volumes with contraction
  • URINE IS CLEAR
  • Post void residual to usually less than 50ccs

Q

treatment of urge incontinence

A
  • Tx = kiegel exercises and bladder relaxation
  • common meds = ditropan and detrol (anticholinergics)
  • -> meds can cause constipation, dry mouth, and can affect CNS

Q

Stress incontinence

A
  • patients lose urine when intraabdominal pressure increases as with coughing, laughing, or lifting
  • this represents failure of sphincter mechanisms to remain closed during bladder filling
  • often due to insufficient pelvic support in women and secondary to trauma from prostate surgery in men

Q

overflow incontinence

A
  • caused by outflow obstruction or impaired detrusor contractility
    (volume builds up until gush of urine)
  • causes of impaired contractility = B12 deficiency, diabetes, tabes dorsalis, alcoholism, spinal diseases
  • outlet obstruction: prostatic hypertrophy, urethral stricture, neoplasia, constipation, large cystocele

Q

Other more unusual causes

A
  • bladder-sphincter dyssynergia (neurological/spinal cord injury), fistulas, reduced detrusor compliance, and recurrent cystitis

Q

evaluation

A
  • history and physical exam
  • precipitant urgency suggest detrusor overactivity
  • Loss of urine wiht cough or strain suggests stress ui
  • continuous leakage suggests sphincter weakness or overflow
  • On physical exam, note functional status, mental status, orthostatic bp and heart rate along with bladder distention and impaction
  • neuro exam looking for signs of cord compression like muscle wasting, hoffman, babinksi signs
  • Sacral root integrity is reflexed by RECTAL TONE and PERINEAL SENSATION

Q

Post void residual

A

have patient empty bladder and then meausre urine volumen left in the bladder by cath or scan
- normal is less than 50 ccs

Q

management

A
  • consider non-pharmacologic therapies
  • decrease caffeine, etoh, and evening fluid
  • for detrusor instability, instruct on relaxation techniques and kiegel exercises. also timed toileting with gradually increasing intervals can be helpful

Q

Management for stress incontinence

A
  • kiegel exercises, biofeedback, PT therapy
17
Q

Pharmacologic management

A
  • estrogen replacement may benefit womenw ith either stress UI or urge UI
  • alpha stimulation with blockage with sudafed may help with stess ui by increasing the tone of the external urethral sphincter
  • anticholinergice therapy may help with urge incontincene
18
Q

surgical therapy

A
  • may benefit some women with stress incontinence who have failed the previous mentioned therapies
19
Q

Catheter care

A
  • use ONLY for CHRONIC urinary retention, to allow skin healing, and when requested by patients and family for comfort
  • used closed system only, aoid topical or systemic antibiotics or catheters treated with antibiotics
  • SILVER alloy hydrogel catheters reduce UTI
  • Consider catheter sling
20
Q

catheter care (bacteria)

A
  • Bacteriuria is universal: terat only if symptoms are present: fever, dysuria, anorexia or delirium
  • replace catheter to get culture
  • nursing home patients with catheters should be in private rooms
  • for acute retention, place catheter for seven to ten days, then remove
  • change about each 6 to 8 weeks
  • for recurrent blockage, increase fluids and consider dilute acetic acid irrigation
