What are the management options for incontinence in elderly males?

Management of Urinary Incontinence in Elderly Males

The management of urinary incontinence in elderly males should follow a stepwise approach beginning with assessment of the type of incontinence, followed by conservative measures, and then pharmacological interventions based on the specific type of incontinence identified. 1, 2

Assessment and Diagnosis

• Initial evaluation should include:

  • International Prostate Symptom Score (IPSS) to quantify symptom severity
  • Physical examination including digital rectal examination (DRE) to assess prostate size
  • Urinalysis to rule out infection or hematuria
  • Frequency-volume chart to assess voiding patterns and identify nocturnal polyuria
  • Post-void residual measurement to assess for incomplete bladder emptying
  • PSA testing if prostate cancer diagnosis would alter management 1, 2

• Identify the type of incontinence:

  • Storage symptoms (urgency, frequency, nocturia) - suggest overactive bladder (OAB)
  • Voiding symptoms (hesitancy, weak stream, intermittency) - suggest benign prostatic obstruction (BPO)
  • Mixed symptoms - combination of storage and voiding symptoms 1

First-Line Management

Conservative Measures (For All Types of Incontinence)

• Lifestyle modifications:

  • Regulate fluid intake (approximately 1.5 liters/day)
  • Reduce intake of caffeine and alcohol
  • Avoid bladder irritants
  • Implement timed voiding schedules
  • Weight loss for overweight patients
  • Avoid sedentary lifestyle 1, 2, 3

• Bladder training:

  • Scheduled voiding with progressive increases in time between voids
  • Particularly effective for urgency incontinence 1, 2

• Pelvic floor muscle exercises:

  • Beneficial for stress or mixed urinary incontinence
  • Can improve symptoms of urgency when performed regularly 1, 2

Pharmacological Management (Based on Incontinence Type)

For Voiding Symptoms (BPO/BPE)

• Alpha-blockers (first-line):

  • Tamsulosin, alfuzosin, silodosin
  • Rapid onset of action (2-4 weeks)
  • Effective for improving urinary flow 1, 2

• 5-alpha reductase inhibitors:

  • Finasteride, dutasteride
  • Recommended for men with enlarged prostate (>30cc) or PSA >1.5 ng/ml
  • Can be used alone or in combination with alpha-blockers
  • Takes 3-6 months for full effect 1, 2

For Storage Symptoms (OAB)

• Behavioral therapy (first-line):

  • Bladder training and timed voiding 1, 2

• Antimuscarinic agents (if behavioral therapy fails):

  • Oxybutynin, trospium, solifenacin, tolterodine
  • Effective for reducing urgency episodes and frequency
  • Caution in men with elevated post-void residual (>200-300 mL) due to risk of urinary retention
  • Side effects include dry mouth, constipation, cognitive effects 1, 2, 4

• Beta-3 adrenergic agonists:

  • Mirabegron
  • Indicated for OAB with symptoms of urge incontinence, urgency, and frequency
  • Better tolerated than antimuscarinics with fewer anticholinergic side effects
  • Demonstrated efficacy in reducing incontinence episodes and micturition frequency 2, 5

For Mixed Symptoms

• Combination therapy:
  • Alpha-blocker + antimuscarinic or
  • Alpha-blocker + 5-alpha reductase inhibitor
  • More effective than monotherapy for appropriate patients 1, 2

Special Considerations for Elderly Males

• Assess for functional incontinence:

  • Mobility limitations
  • Cognitive impairment
  • Environmental barriers to toileting 1

• Medication review:

  • Identify and modify medications that may contribute to incontinence (diuretics, sedatives, antidepressants) 3

• Avoid indwelling catheters:

  • If used, remove within 48 hours to reduce risk of urinary tract infection
  • Consider silver alloy-coated catheters if catheterization is necessary 1

• For patients with cognitive impairment:

  • Prompted voiding can be effective
  • Implement a regular toileting schedule 1

Follow-up and Monitoring

• Reassess patients 4-12 weeks after initiating treatment
• Evaluate symptom improvement using IPSS
• Consider post-void residual and uroflowmetry during follow-up
• Annual reassessment if symptoms are stable 1, 2

When to Refer to a Specialist

• Persistent bothersome symptoms despite initial management
• Recurrent urinary tract infections
• Hematuria
• Significant post-void residual
• History of prior pelvic surgery or radiation
• Suspected neurological cause of incontinence 1, 2

Treatment Algorithm

1. Initial Assessment → Determine type of incontinence
2. Conservative Management → Lifestyle modifications + bladder training + pelvic floor exercises
3. If predominantly voiding symptoms → Alpha-blocker (± 5-alpha reductase inhibitor if enlarged prostate)
4. If predominantly storage symptoms → Continue bladder training → If inadequate response, add antimuscarinic or mirabegron
5. If mixed symptoms → Alpha-blocker + bladder training → If storage symptoms persist, consider adding antimuscarinic or mirabegron
6. If inadequate response → Refer to specialist for advanced therapies

This structured approach to managing urinary incontinence in elderly males focuses on identifying the type of incontinence and implementing appropriate interventions to improve continence, quality of life, and reduce morbidity associated with this condition.
