Week 8: GU, Sexual Health & Renal Flashcards
What is stress incontinence
Involuntary loss of urine with increased intra- abdominal pressure
What is urge incontinence
= the urge to void immediately preceding or accompanying involuntary urine leakage
Patients are aware of the intense need to avoid but are unable to hold back urine
What is the difference between urge incontinence and over active bladder (OAB)?
“Overactive bladder” is a term that describes a syndrome of urinary urgency with or without incontinence, which is often accompanied by nocturia and urinary frequency
The terms “urgency incontinence” and “overactive bladder with incontinence” are often used interchangeably.
T/F with urge incontinence, the person typically piddles a little
False
typically the entire contents of the bladder are lost rather than a few drops.
**although up to date says it can be either
Risk factors for urge incontinence (includes many associated medical conditions)
Urgency urinary incontinence is more common in older women and may be associated with comorbid conditions that occur with age.
May be idiopathic or secondary to other conditions…
Medical: CHF, DM, diuretics
Neurogenic: MS, PD, CVD, dementia, SCI
Bladder outlet obstruction: Previous bladder neck surgery, pelvic organ prolapse
Gyne: UTI, pregnancy, pelvic mass, urethral diverticulum, child birth
Psychosomatic: habits, anxiety, high fluid consumption
Obesity
Smoking
Stroke
Prior radiation to pelvis
Prostate: BPH, CA
What is thought to cause urge incontinence? Basic patho
Thought to result from detrusor overactivity, leading to uninhibited contraction during bladder filling
Bladder hypersensitivity
What the heck is the detrusor muscle?
The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle
S&S of urge incontinence
-You have a sudden, intense urge to urinate followed by an involuntary loss of urine.
Frequency
Nocturia
Diagnostics we may order for someone with urge incontinence?
-UA (UC if indicated)
-PVR
-Bladder stress test
What are considered bladder irritants & should be avoided with urge incontinence?
caffeine
smoking
alcohol
acidic, spicy foods
carbonated beverages
What are the 1st line treatments for urge incontinence?
Non pharm (1st line, try for 6+ weeks)
- PELVIC FLOOR PHYSIO!
-Reduce bladder irritants (caffeine, smoking, alcohol, carbonated)
-Fluid restriction
Bladder training: Regular voiding schedule
- Voiding diary
-Distraction techniques when urge comes on: deep breathing, crosswords…
-Encourage double voiding/ complete emptying.
-OTC products (pads, incontinence underwear, urine wicking devices)
How should you instruct a patient to carry out a regular voiding schedule for stress incontinence?
Start timed voiding q1 hour, then increased by 15-30min/ wk or until 2d without incontinence
goal 3-4 hour without leaks
*want to avoid last minute rush to bathroom./
If 6 or so weeks of nonpharmacologic strategies doesn’t fix urge incontinence, we can start to consider drugs. What are our typical pharm treatments?
Anticholinergics (oxybutynin, tolterodine, fesoteriodine, …) - These act at detrusor smooth muscle to reduce over activity.
B3 adrenergic agonist (mirabegron) (increases bladder capacity)
Vaginal estrogen in estrogen deficient females
If pharm management of urge incontinence is inadequate. What kind of procedures can be helpful?
**once has failed 2 adequate trials of meds (4-12 weeks each):
Sacral neuromodulation (SNM)
Detrusor botox injection
Laser therapy
Intravesicular instillations
Red flags warranting referral for incontinence
recurrent incontinence, incontinence assoc with pain, UT abnormalities, hematuria, recurrent infection, fistulas, prostate/ pelvic irradiation, previous radical pelvic sx, pelvic mass, lack of tx response
What is the most common cause of incontinence in Canada?
stress (~50%)
How common is urge urinary incontinence/OAB in Canada?
~16% of those with incontinence
Which kind of urinary incontinence is typically the most responsive to pharm tx?
Urge/OAB
What is the basic patho of stress incontinence?
-Thought to be related to lack of mechanical support of urethra/ insufficient resistance to outflow of urine with increased abdo pressure
-Sphincter incompetence
Risk factors for stress incontinence?
-20-30% of F (F>M)
increased age
obesity
pregnancy/ vaginal delivery
post menopause
smoking/ chronic cough
neurological
genetics
high impact exercise
-Can also occur in M post prostate Ca tx (or rarely surgical tx BPH)
S&S of stress incontinence
Leakage of urine with state increased intra abdominal pressure (cough, sneeze, laugh, sex)
The urine leakage may be an occasional drop or dribble if the condition is mild. In severe cases, you may leak a stream of urine
*I don’t think it usually involves irritative signs like dysuria or frequency, but some sources say it may…
What investigations might you order for stress incontinence?
UA (if hematuria and irritative voiding symptoms: cytology; if pyuria/ bacteria: UC)
-PVR
What is a normal PVR?
normal is <1/3 total volume, abnormal is >1/3 and indicates poor bladder contractility or bladder outlet obstruction
Nonpharm treatment of stress incontinence
-urinary diary
-weight loss, smoking cessation
-Pelvic floor PT (kegels) (x8-12 weeks, then r/a)
-Devices for biofeedback or electrical stimulation (vaginal electromyography probe for biofeedback, vaginal cones, non implantable electrical stimulation)
-Pessaries to decrease leakage (or for pelvic organ prolapse)
