• To define– incontinence
• To learn– Risk factors for incontinence– Diagnosis of the type of incontinence
• To manage – An incontinent woman
Objectives
DefinitionDefinition
• Urinary incontinence is the inability to control urination which results in unintended urinary flow or leakage
• Urinary incontinence is the inability to control urination which results in unintended urinary flow or leakage
Classification of UIClassification of UI
• 6 major subtypes of urinary incontinence:
– Stress
– Urge (“overactive bladder”)
– Mixed
– Overflow
– Functional
– Other (deformity/lack of continuity)

Stress incontinenceStress incontinence
• Signs & Symptoms: – urine leakage triggered by coughing,
sneezing, laughing, lifting, exercising, straining
– usually worse standing than supine– small to moderate volumes of urine– infrequent nocturnal leakage– little post-void residual
• Signs & Symptoms: – urine leakage triggered by coughing,
sneezing, laughing, lifting, exercising, straining
– usually worse standing than supine– small to moderate volumes of urine– infrequent nocturnal leakage– little post-void residual
Stress incontinenceStress incontinence
• Causes: – urethral hypermobility due to pelvic floor laxity
– aging– difficult or multiple vaginal deliveries– hysterectomy – other perineal injury (e.g. radiation)
– intrinsic urethral sphincter deficiency – autonomic neuropathy– inadequate estrogen levels – partial denervation

Stress incontinenceStress incontinence
Urge incontinence (overactive bladder, detrusor instability)
Urge incontinence (overactive bladder, detrusor instability)
• Symptoms: – Frequent abrupt, intense urge to urinate that cannot
be voluntarily suppressed– moderate to large volumes of urine– nocturnal wetting– perineal sensation intact
• Symptoms: – Frequent abrupt, intense urge to urinate that cannot
be voluntarily suppressed– moderate to large volumes of urine– nocturnal wetting– perineal sensation intact
Urge incontinence (overactive bladder, detrusor instabiliy)
Urge incontinence (overactive bladder, detrusor instabiliy)
• Cause: – Inappropriate contraction of detrusor muscle during
bladder filling– idiopathic– related to aging (unclear mechanism)– decreased cortical inhibition (CVA, Parkinson’s disease,
Alzheimer’s disease, brain tumor)– bladder irritation (UTI, bladder CA, stones)

• Refers to patients with both stress incontinence and urge incontinence.
• Helpful to identify the most bothersome symptom and treat accordingly

Overflow incontinenceOverflow incontinence
• Signs & Symptoms: – Frequent voiding/dribbling (worse after fluid load or diuretic)– small volumes– without warning– slow or weak flow– incomplete bladder emptying– feel need to strain– nocturnal wetting
• Bladder hypotonic/flaccid and palpably distended • Large post-void residual (PVR)

• Bladder hypotonic/flaccid and palpably distended • Large post-void residual (PVR)
Overflow incontinenceOverflow incontinence
• Causes:– long-standing outlet obstruction
– detrusor chronically overstretched– detrusor insufficiency
– lower motor neuron damage due to peripheral neuropathy or sacral cord injury
– impaired sensation – peripheral neuropathy, Vit B12 deficiency, SCI
– medications that reduce detrusor tone – anticholinergics, antidepressants, antipsychotics, anti-
Parkinsonians, narcotics, Ca-channel blockers, vincristine

Overflow incontinenceOverflow incontinence
Functional IncontinenceFunctional Incontinence
• Inability to void independently due to impairment of physical and/or cognitive function
– disabling illness, bedridden– frontal lobe dysfunction, lack of awareness– deliberate incontinence (rare)
• Patient may have other types of incontinence that are amenable to treatment
• Pure functional incontinence should be a diagnosis of exclusion
• Inability to void independently due to impairment of physical and/or cognitive function
– disabling illness, bedridden– frontal lobe dysfunction, lack of awareness– deliberate incontinence (rare)
• Patient may have other types of incontinence that are amenable to treatment
• Pure functional incontinence should be a diagnosis of exclusion
Deformity or Lack of ContinuityDeformity or Lack of Continuity
• Causes:– Vesicovaginal or ureterovaginal fistula, often
as complication of hysterectomy or other pelvic surgery
– Ectopic ureters– Diverticulae

• OB/Gyn Hx– gravity/parity– # of vaginal, instrument
assisted and C/S deliveries– interval between deliveries– previous hysterectomy,
vaginal and/or bladder surg– pelvic RT– trauma– estrogen status

Bladder DiaryBladder Diary
• 24-48 hours
• Requires literacy and significant amount of time and work by patient
• see sample in handout

Physical ExamPhysical Exam
• If screen (+) for UI:
• Have pt void as normally and completely as possible immediately before exam
• Record volume voided
• Determine PVR within 10 minutes by catheterization (send urine for UA & Cx)
• PVR > 100ml considered abnormal
• If screen (+) for UI:
• Have pt void as normally and completely as possible immediately before exam
• Record volume voided
• Determine PVR within 10 minutes by catheterization (send urine for UA & Cx)
• PVR > 100ml considered abnormal
Physical Examination
• General examination
• Neck examination (cervical spondylosis)
– should investigate limitations in cervical lateral rotation and lateral flexion,
– interosseous muscle wasting, – Babinski reflex +
interruption of inhibitory tracts to the detrusor
detrusor overactivity
Physical Examination
• Back examination – may reveal dimpling or a
hair tuft at the spinal cord base, suggestive of occult dysraphism
Physical Examination
• Cardiovascular examination should look for evidence of volume overload.
• Abdomen should be palpated for masses, tenderness, and bladder distention.
• Extremities should be examined for joint mobility and function.
Physical Examination
• Genital examination – Inspection of the vaginal mucosa
(atrophy, narrowing of the introitus by posterior synechia, vault stenosis, and inflammation)
– A bimanual examination (masses or tenderness)
– Pelvic floor muscle strength
• Rectal examination – Masses and fecal impaction
Pelvic-floor muscle assessment International Continence Society
1—no response, cannot perceive
2—weak squeeze, felt as a flick
3—moderate squeeze, felt all around finger
4—strong squeeze, full fingers compressed
Messelink EJ et al Neurourol Urodynam 2005;24:374–80
Physical Examination
• Neurologic examination – Sacral root integrity
• perineal sensation, • tone of the anal sphincter• the bulbocavernosus reflex
– Cognitive status,– Motor strength and tone,– Peripheral sensation for
peripheral neuropathy
Q-tip test
Sensitivity Specifity
Postvoid Residual Measurement
• Rules out urinary retention• Poor test-retest reliability (limited
use)• PVR < 100 cc normal
> 200 cc abnormally
100-200 cc borderline → further investigation
1. Catheter or cystoscope2. Radiography
excretion urography, micturition cystography
3. USG4. Radioisotopes

Pad Tests
• The most useful objective urine loss test in clinical practice
• Normal range: < 2 g of urine/h2-10gr Mild10-50gr Moderate> 50gr Severe
• Pad tests are not recommended in the routine assessment of women with UI
RCOG 2006
Urodynamic testingUrodynamic testing
• PVR: simple test for overflow incontinence• Cystometry: dx of complicated mixed conditions
– Normal: sense filling between 100-200ml
– non-urgent desire to void at 250-350ml– detrusor contraction at 400-550ml
• Uroflowmetry: info on outflow obstruction• Cystoscopy: detects structural abnormalities,
inflammation, masses• IVP: detects structural abnormalities, urethral narrowing,
incomplete bladder emptying
• PVR: simple test for overflow incontinence• Cystometry: dx of complicated mixed conditions
– Normal: sense filling between 100-200ml
– non-urgent desire to void at 250-350ml– detrusor contraction at 400-550ml
• Uroflowmetry: info on outflow obstruction• Cystoscopy: detects structural abnormalities,
inflammation, masses• IVP: detects structural abnormalities, urethral narrowing,
incomplete bladder emptying
Endoscopy
• provide unique anatomical information with a simple, minimally invasive approach
• adjunct to multichannel urodynamics in women with possible ISD, urethral diverticula, urogenital fistulae, foreign bodies or urothelial lesions
• Cystoscopy is not recommended in the initial assessment of women with UI alone

Anticholinergic Drugs (Urge UI)
• Oxybutynin• Tolterodine• Trospium• Darifenacin• Variety of preparations: Immediate Release;
Extended Release; Transdermal• Outcomes same; Try different agent if one
doesn’t work***** ALL these drugs suppress the detrusor contractility and MAY CAUSE
