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 to perform urodynamic testing to evaluate the functional status of the lower urinary tract before proceeding with surgical reconstruction. 1

Diagnostic Evaluation

When evaluating a patient with urinary incontinence and a scarred, open proximal urethra, a structured approach is necessary:

1. Urodynamic Testing: This is essential for non-index patients with complex presentations, especially those with:

   • Evidence of urethral damage/scarring
   • History of prior surgeries
   • Mismatch between subjective and objective findings 1

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

   • Assess the integrity of the lower urinary tract
   • Evaluate the extent of urethral scarring
   • Determine the precise location of the open proximal urethra 1

3. Imaging Studies: Consider additional imaging to fully characterize the urethral defect:

   • Retrograde urethrography
   • Voiding cystourethrography
   • Pelvic MRI (to assess surrounding tissue damage) 1

Treatment Algorithm

Based on the scarred, open proximal urethra and urinary incontinence, the treatment pathway should follow this sequence:

Step 1: Complete Diagnostic Workup

• Urodynamic testing to characterize the type and severity of incontinence
• Cystoscopy to visualize the urethral defect
• Imaging to determine the extent of scarring

Step 2: Address Any Underlying Conditions

• Treat any urinary tract infection
• Manage any concurrent bladder neck contracture or vesicourethral anastomotic stenosis before addressing incontinence 1

Step 3: Surgical Planning

For a scarred, open proximal urethra with incontinence, surgical options include:

• Artificial Urinary Sphincter (AUS): The gold standard for severe incontinence with urethral damage 1
• Urethral Reconstruction with Sling Placement: For cases with significant urethral defects 1, 2
• Pubovaginal Sling: Should be considered at the time of urethral reconstruction 2

Important Considerations

1. Avoid Repeated Endoscopic Procedures: Multiple endoscopic interventions in cases of urethral scarring can increase morbidity and delay definitive treatment 1

2. Timing of Reconstruction: Definitive urethral reconstruction should only be planned after:

   • Complete evaluation of the defect
   • Patient is medically stable
   • Tissue conditions are optimal for reconstruction 1

3. Potential for Failure: Patients with scarred urethras have higher failure rates with standard sling procedures; therefore, an artificial urinary sphincter may be more appropriate 1

4. Post-Surgical Monitoring: After reconstruction, patients should be monitored for at least one year for:

   • Recurrent stricture formation
   • Persistent incontinence
   • Voiding dysfunction 1

Pitfalls to Avoid

• Rushing to Surgery: Without proper urodynamic assessment, the wrong procedure might be selected
• Underestimating the Defect: Scarred, open proximal urethras often require more complex reconstruction than standard incontinence procedures
• Overlooking Concurrent Conditions: Bladder dysfunction (overactivity, poor compliance) must be addressed alongside the urethral defect 1
• Inadequate Follow-up: These complex cases require vigilant monitoring for complications

In cases where multiple reconstructive attempts fail or the urethral damage is too extensive, urinary diversion may be considered as a last resort for patients who cannot achieve satisfactory quality of life with other treatments 1.
