Next Best Step for Patient with Urinary Incontinence and Scarred, Open Proximal Urethra

For a patient with urinary incontinence and a scarred, open proximal urethra, the next best step is urodynamic testing followed by artificial urinary sphincter (AUS) placement as the definitive treatment option. 1

Diagnostic Evaluation

When evaluating a patient with urinary incontinence and a scarred, open proximal urethra, the following diagnostic steps are essential:

1. Urodynamic Testing: This is critical for non-index patients, particularly those with anatomical abnormalities like a scarred, open proximal urethra 1

   • Helps determine the type and severity of incontinence
   • Assesses bladder and urethral function
   • Evaluates for detrusor overactivity

2. Cystoscopy: While not routinely recommended for simple stress urinary incontinence (SUI), it is indicated in this case to:

   • Evaluate the extent of urethral scarring
   • Assess the condition of the bladder neck
   • Rule out other urological abnormalities 1

3. Imaging: Consider cross-sectional imaging (CT or MRI) to:

   • Assess the proximal extent of urethral damage
   • Evaluate pelvic anatomy
   • Rule out other contributing factors 1

Treatment Algorithm

Step 1: Confirm Type and Severity of Incontinence

• Urodynamic testing will likely confirm stress urinary incontinence due to the scarred, open proximal urethra
• Rule out mixed incontinence that might require additional treatment approaches

Step 2: Consider Conservative Management

• Pelvic floor muscle exercises may provide minimal benefit but are unlikely to be sufficient given the anatomical defect
• Conservative management alone is unlikely to be successful with significant anatomical abnormalities 1

Step 3: Surgical Intervention

• Artificial Urinary Sphincter (AUS): This is the gold standard treatment for patients with a scarred, open proximal urethra 1

  • Provides the best long-term continence outcomes
  • Specifically designed to address sphincteric incompetence
  • Particularly indicated when there is urethral scarring or prior failed treatments

• Male sling procedures are contraindicated in this scenario as they have poor outcomes in patients with scarred urethras or proximal urethral incompetence 1

Important Considerations

• Pre-surgical Evaluation: Any symptomatic vesicourethral anastomotic stenosis or bladder neck contracture should be treated before proceeding with incontinence surgery 1

• Post-surgical Follow-up: Patients should be monitored for at least one year for complications such as:

  • Device infection or erosion
  • Mechanical failure
  • Persistent or recurrent incontinence 1

• Patient Counseling: Patients should understand:

  • The need for manual dexterity to operate the AUS
  • Potential complications and success rates
  • The possible need for revision surgery in the future

Pitfalls to Avoid

1. Undertreatment: Studies show that up to 71% of patients with urinary incontinence receive no active treatment within a year of diagnosis 2. Given the anatomical defect described, active intervention is necessary.

2. Inadequate Evaluation: Failure to perform urodynamic testing may lead to misdiagnosis of the type of incontinence and inappropriate treatment selection.

3. Attempting Endoscopic Procedures: For scarred urethras, endoscopic procedures have high failure rates and may delay definitive treatment 1.

4. Overlooking Concomitant Conditions: Patients with urethral scarring may also have bladder dysfunction that requires additional management 1.

In cases where AUS fails or is contraindicated, urinary diversion may be considered as a last resort for patients who cannot achieve satisfactory quality of life with other interventions 1.
