Urinary Incontinence
Aka: Urinary Incontinence, Incontinence
- Epidemiology
- Increased prevelance with age
- Age 44 year women: 17%
- Age 75 year women: 27%
- High Incidence in female athletes
- Female Varsity Athletes: 32%
- Female Basketball players: 68%
- Physiology
- Physiology of urination and Bladder control
- Detrussor muscle (Bladder) control
- Parasympathetic innervation
- Beta adrenergic control
- Internal Urethral sphincter
- Alpha adrenergic control
- External Urethral sphincter
- Somatic or voluntary control
- Incontinence is not a normal part of aging
- Age predisposes to Incontinence
- Age does not cause Incontinence
- Pathophysiology
- Disorders of Urinary Storage
- Detrussor Hyperactivity
- Urge Incontinence
- Sphincter incompetence
- Urge Incontinence
- Stress Incontinence
- Disorders of Urine Emptying
- Detrussor hypoactivity
- Overflow Incontinence
- Urethral Sphincter obstruction
- Overflow Incontinence
- Types of Urinary Incontinence
- Low Pressure Urethra (Type 3)
- Urethral tone loss (<60 cm H20)
- Causes: trauma, surgery
- Overflow Incontinence (Urinary Retention)
- Bladder overdistention with Urinary Retention
- Post-void residual >200 cc of urine
- Less common in women
- Causes: Neuropathy, BPH, or pelvic mass
- Requires evaluation for tumor mass
- Urge Incontinence (Overly sensitive Bladder)
- Loss of large Bladder volumes (contrast with stress)
- Associated with urinary urgency, frequency, nocturia
- Causes: CNS, Cystitis, Bladder Cancer, stones
- Stress Incontinence (Loss of pelvic support at Urethra)
- Loss of small Bladder volumes (contrast with urge)
- Occurs with coughing, sneezing, lifting
- Causes: Urethral hypermobility, Sphincter damage
- Functional Incontinence
- Normal Bladder with decreased access to toilet
- Differential Diagnosis: (Mneumonic: "DIAPPERS") - Causes transient acute Incontinence
- Delirium
- Infection or Inflammation
- Recurrent Urinary Tract Infection
- Infectious Vaginitis
- Interstitial Cystitis
- Carcinoma-in-situ of the Bladder
- Atrophic Urethritis or Atrophic Vaginitis
- Pharmaceuticals
- Diuretics
- Sedative-Hypnotic Medications
- Antipsychotic medications
- Antidepressants
- Analgesics including Narcotics
- Muscle relaxants
- Sympathetic blockers
- Psychological causes
- Excessive urine output (e.g. Diabetes Mellitus)
- Restricted Mobility (i.e. difficult ambulation)
- Stool Impaction
- Exam
- Spontaneous loss of urine
- Detrussor Instability
- Urge Incontinence
- Provocation with cough, valsalva, or bearing down
- Suggests Stress Incontinence
- Perform Pelvic exam, lifting anterior vaginal wall
- Changes Bladder neck position
- Retest with cough or valsalva
- Spontaneous uncontrolled large volume Bladder emptying
- Suggests Urge Incontinence
- Diagnosis
- See Provoked Full Bladder Stress Test
- Urodynamic Testing (Cystometrography)
- Indicated for Incontinence not due to stress or urge
- Evaluation
- Rule-out reversible cause
- Medication adverse effects
- Atrophic Vaginitis
- Benign Prostatic Hyperplasia (BPH)
- Polyuria
- Medication
- Diabetes Mellitus
- Fecal Impaction
- Urinary Tract Infection
- Functional Incontinence
- Limited mobility
- Altered Level of Consciousness
- Rule-out Overflow Incontinence
- Check post-void residual if indicated by history
- Consider neurologic or post-surgical cause
- See Low Pressure Urethra
- Distinguish Urge Incontinence from Stress Incontinence
- If secondary cause is unlikely
- Management: General
- Management is per specific Incontinence cause
- Make toilets more accessible
- Higher toilets
- Well lit floors
- Change bedroom to be close to bathroom
- Consider bedside commode
- Wear clothes that are removed easily
- Use moderation in fluid intake
- Lose weight (if obese)
- Smoking Cessation
- Avoid Diuretics
- Avoid Alcohol
- Avoid caffeine
