Urinary & faecal incontinence Flashcards
Define urinary Incontinence
The complaint of involuntary loss of urine after having gained the control on voiding.
LUTS: Storage symptoms:
• Frequency, Nocturia, Urgency, Incontinence
LUTS: Voiding symptoms:
• Slow stream, splitting/ spraying, intermittency, hesitancy, straining,
terminal dribble
LUTS: Post-micturation symptoms:
• Sense of incomplete evacuation,
post-micturation dribble
Gender diferences in incontinente
Storage LUTS >Voiding and post-micturation LUTS in both
sexes.
Stress incontinence more common in women Urge incontinence more common in men
Normal Micturation stages
- Realize need to void urine
- Plan the act
- Recognize appropriate place • Negotiate environment
- Manage clothing
Types of incontinence
- Urge (OAB)
- Stress
- Overflow
- Functional
- Mixed
Risk Factors fir incontinance
- Age: SI-peaks in middle age, Urge & mixed UI increase after 50 years in women
- Heredity
- Race: SUI in white women > Hispanic/ black
- Physical activity
- High BMI: Highest quartile of body mass-2-4 times more incidence of UI than lowest
- Diet - High fat, low residue diet, Tea, fizzy drinks, water intake
- Infection (Asymptomatic bacteriuria!!)
- Smoking, cough, Chr. Lung diseases
Disability/disease related (Falls/Leg weakness/postural hypotension, Impaired mobility, visual impairment, Cognitive impairment, DM, constipation
Surgery: Prostatectomy, Hysterectomy • Hormone replacement worsens UI
Medications that increase risk of incontinence
- Diuretics
- Sedatives
- Choline esterase inhibitors
- Alpha blockers
- Digoxin, frusemide: anticholinergic effects.
- Antimuscarinics can worsen cognitive function and make incontinence worse.
Urge Incontinence mechanism
- Detrusor muscle is overactive
- Contracts unpredictably
- Cytometry shows uninhibited contractions
- Constant fear of not making to toilet in time
Definition of stress incontinence
Involuntary leakage of urine on
• effort or
• exertion or
• on coughing or sneezing
Mechanism of Urethral closure
- Urethral Smooth muscle
- Striated muscle of urethra
- Mucosa and Connective tissue
Continence depends on what three factors:
- Urethral closure pressure
- Abdominal pressure
- Transmission of the pressure
Overflow incontinence pathophysiology
- Impaired voiding due to
- Outflow obstruction e.g. BPH
- Lower motor neuron lesion, i.e. neuropathic bladder
- Usually sub acute or chronic, painless retention of urine. • Dribbling, Nocturia
Differentiating Urge Vs Stress UI
Urge UI
Sudden severe desire
Need to wake up at night
Stress UI
Making to the toilet
Leaking on physical activity
