Management of Male Stress Urinary Incontinence
Start with pelvic floor muscle exercises (PFME) immediately after catheter removal if post-prostatectomy, and if incontinence persists beyond 6 months with bothersome symptoms despite conservative therapy, proceed directly to surgical intervention with artificial urinary sphincter (AUS) as the gold standard for moderate-to-severe incontinence. 1
Initial Conservative Management
Pelvic Floor Muscle Training
- Offer PFME/PFMT to all post-prostatectomy patients immediately upon catheter removal 1
- This accelerates time-to-continence recovery (improvement seen at 3-6 months)
- However, overall continence rates at 1 year remain similar whether PFME was performed or not
- This means PFME speeds recovery but doesn't change ultimate outcomes
Timeline Expectations
- Most men are NOT continent at catheter removal—counsel patients this is normal 1
- Continence generally improves to near baseline by 12 months post-surgery 1
- Surgery may be considered as early as 6 months if incontinence is not improving despite conservative therapy 1
Surgical Management Algorithm
Patient Stratification by Severity
Mild Incontinence (1-2 pads/day):
- Male urethral slings are appropriate
- Success rates: 70-90% 2
- Do NOT use slings for severe incontinence—they have poor efficacy 3
Moderate-to-Severe Incontinence (≥3 pads/day):
- Artificial urinary sphincter (AUS) is the gold standard 1
- Success rates: 73-93% 2
- Most efficacious and durable option 4
Post-Radiation Patients:
- AUS is preferred over male slings or adjustable balloons 1, 3
- Radiation increases complication rates and decreases efficacy for all devices
- AUS revision rates are higher in radiated patients (risk ratio 1.56) 3
- Modern radiation techniques (post-2007) show equivalent outcomes to older techniques 3
Specific Surgical Options
Artificial Urinary Sphincter (AUS):
- Gold standard with over 30 years of published data 5
- Counsel patients that device will likely lose effectiveness over time 1
- Failure rates: ~24% at 5 years, ~50% at 10 years 1
- Reoperations are common but expected
- Can be replaced same-day if mechanical failure (not infected)
- If infected: explant all components, wait 3-6 months before replacement 1
Male Urethral Slings:
- Appropriate for mild incontinence only
- Contraindicated in severe SUI 3
- Lower complication rates than AUS
- If sling fails, proceed to AUS 1
Adjustable Balloon Devices (ProACT):
- May offer to non-radiated patients with mild-to-severe SUI 3
- Cure/improvement rates: 55%/80% respectively 3
- Higher intraoperative complication rates than other procedures 3
- Urethral/bladder perforation: 5.3% 3
- Mean explantation rate: 27% 3
- Requires serial contrast adjustments in clinic for optimization
- Less long-term data available
Urethral Bulking Agents:
- Least invasive but also least effective 1
- Consider only for patients who refuse or cannot tolerate more invasive surgery
- Best results in: high Valsalva leak point pressure, unscarred anastomosis, no radiation history 1
Special Considerations
Post-BPH Surgery Incontinence
- Evaluate and treat identically to post-prostatectomy incontinence 1
- Offer sling or AUS if conservative measures fail
- Persistent SUI rate: 0-8.4% after BPH surgery
Bladder Neck Contracture/Stricture
- Treat any vesicourethral anastomotic stenosis (VUAS) or bladder neck contracture (BNC) BEFORE anti-incontinence surgery 1
- These obstructions decrease sling success rates
- AUS is preferred over slings in patients with VUAS/BNC 1
Concomitant Erectile Dysfunction
- Concomitant or staged procedures may be offered 1
- Counsel about possible increased complication risk with simultaneous surgery
Device Failure Management
- Re-evaluate with history, physical exam, cystoscopy, and cross-sectional imaging 1
- For AUS: check if device deactivated, assess cuff coaptation, measure reservoir fluid volume
- Consider cuff relocation (proximal), downsizing, or tandem cuff placement 1
- For failed sling: proceed to AUS 1
Common Pitfalls to Avoid
- Don't rush to surgery before 6 months unless severe symptoms with no improvement
- Don't use slings for severe incontinence—they will fail
- Don't use slings as first-line in radiated patients—use AUS
- Don't forget to treat strictures/contractures first—they worsen outcomes
- Don't replace infected AUS immediately—wait 3-6 months minimum
- Don't underestimate AUS revision rates—counsel patients about 50% failure at 10 years
Last Resort Options
For patients unable to achieve acceptable quality of life after multiple device failures:
- Urinary diversion ± cystectomy may be considered 1
- Appropriate for intractable bladder neck contracture or severe detrusor instability
- Requires appropriate patient motivation and extensive counseling
