What is the best management approach for a patient with daily urinary leakage post-prostatectomy (post removal of the prostate gland)?

Management of Daily Urinary Leakage Post-Prostatectomy

Start pelvic floor muscle exercises immediately and continue conservative management for at least 6 months before considering surgical intervention, unless incontinence is severe and not improving. 1, 2

Initial Assessment

Evaluate the patient to determine:

• Type of incontinence: Stress urinary incontinence (most common, caused by sphincteric insufficiency) versus urgency incontinence (bladder dysfunction) versus mixed incontinence 1, 3
• Severity: Activities that trigger leakage, volume of urine loss, number of pads used daily 1
• Timeline: How long post-surgery and whether symptoms are improving or stable 1
• Degree of bother: Impact on quality of life 1

If the type cannot be definitively determined from history and physical exam, consider urodynamic testing or pad testing. 1

Conservative Management (First-Line for 6-12 Months)

For Stress Urinary Incontinence (Most Common)

• Pelvic floor muscle exercises (PFME) should be offered immediately after catheter removal 1, 2
• PFME accelerates continence recovery in the first 3-6 months, though overall continence rates at 1 year may be similar regardless 1, 3
• Most men achieve continence (no pad required) within 12 months of surgery 1

For Urgency or Mixed Incontinence

• Bladder training combined with PFME for urgency components 3
• Pharmacologic therapy if urgency predominates:
  • Solifenacin is first-choice: Most effective with lowest discontinuation rate due to side effects (NNTB: 9 for continence) 3
  • Tolterodine is an alternative: Similar efficacy (NNTB: 12 for continence) 3
  • Avoid oxybutynin: Highest risk for discontinuation from adverse effects 3
  • Common side effects include dry mouth, constipation, and blurred vision 3

Surgical Management (After 6-12 Months)

Surgery may be considered as early as 6 months if incontinence is not improving despite conservative therapy. 1, 2

Indications for Surgical Intervention

• Patients showing no significant improvement after 6 months 1
• Patients with severe incontinence at 6 months 2
• Patients who remain incontinent at 1 year post-procedure 2

Surgical Options

• Artificial urinary sphincter (AUS) is the gold standard, particularly for:

  • Severe incontinence 1
  • Patients with history of radiation therapy 1, 2
  • Expected outcome: approximately one thin pad per day 1

• Male slings can be offered as an alternative with appropriate counseling 1

Important Surgical Counseling Points

• AUS effectiveness decreases over time: 24% failure rate at 5 years, 50% at 10 years 2
• Radiation history increases erosion risk (relative risk 2.97) 1
• If AUS fails, it can be revised or replaced 1

Special Considerations

Climacturia (Urinary Leakage During Sexual Activity)

This affects 20-93% of men post-prostatectomy and requires specific management: 3, 4

• Empty bladder prior to sexual activity 1, 3
• Use condoms to catch urine 1, 3
• Achieve orgasm while supine 1
• Continue PFME 1, 3
• Both AUS and transobturator male slings show high rates of improvement in climacturia 1

Timeline Expectations

• At catheter removal: Most men are not continent 1
• 3 months: 34-77% continent depending on presence of anastomotic leak 5
• 6 months: 76-80% continent 5
• 12 months: 90-93% continent; incontinence expected to improve to near baseline 1, 5

Common Pitfalls to Avoid

• Do not rush to surgery: Most patients improve significantly within the first year 1
• Do not use oxybutynin first-line for urgency symptoms due to high adverse effect profile 3
• Do not ignore urgency components: Up to 48% of patients have overactive bladder symptoms requiring specific treatment 1
• Screen for climacturia: Patients may not volunteer this information but find it highly bothersome 4
