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, surgical reconstruction with an artificial urinary sphincter (AUS) is the most appropriate next step. This recommendation is based on the AUA/SUFU guidelines for incontinence after prostate treatment, which provide the most relevant guidance for managing urethral damage with incontinence 1.

Diagnostic Evaluation

Before proceeding with surgical intervention, a thorough assessment should be completed:

1. Confirm stress urinary incontinence: Verify that the incontinence is due to the scarred, open proximal urethra through:

   • Cystourethroscopy to assess urethral and bladder pathology 1
   • Urodynamic testing to rule out detrusor overactivity or other bladder dysfunction 1

2. Assess severity of incontinence:

   • Determine pad usage per day
   • Evaluate impact on quality of life
   • Document duration of symptoms

Treatment Algorithm

Based on the AUA/SUFU guidelines, the treatment approach should follow this algorithm:

For Severe Incontinence with Scarred Urethra:

1. Artificial Urinary Sphincter (AUS): First-line surgical option for severe incontinence with compromised urethral integrity 1

   • Provides superior continence outcomes in patients with anatomical defects
   • Particularly indicated when there is a scarred, open proximal urethra

2. Male Sling Procedures: Not recommended as first-line for patients with scarred urethras

   • The AUA/SUFU guidelines specifically note that patients with vesicourethral anastomotic stenosis or bladder neck contracture have decreased success rates with male slings 1
   • A scarred, open proximal urethra represents a similar anatomical challenge

Important Considerations

• Urethral Evaluation: Prior to AUS placement, complete urethral evaluation is essential to assess the extent of scarring 1

• Surgical Planning: The cuff size and placement location must be carefully determined based on the condition of the urethra 1

• Post-operative Management: Patients should be counseled that the expected outcome is reduction to one thin pad per day, not necessarily complete dryness 1

Alternative Options to Consider

If AUS is not feasible or fails:

1. Urethral Reconstruction: For severe urethral scarring, reconstruction may be necessary before continence procedures 2

   • Options include vaginal flaps (for female patients) or urethral reconstruction techniques

2. Urinary Diversion: In extreme cases where reconstruction is not possible

   • The AUA/SUFU guidelines state: "A urinary diversion can be considered in patients who are unable to obtain long-term quality of life after incontinence after prostate treatment" 1

Pharmacological Management

While awaiting surgical intervention, symptomatic management may include:

• For urgency component: Antimuscarinic medications like oxybutynin may help manage any concurrent overactive bladder symptoms 3
• Behavioral therapies: Pelvic floor muscle exercises, though likely to have limited benefit with anatomical defects 1

Conclusion

The scarred, open proximal urethra represents a significant anatomical defect causing stress urinary incontinence. While conservative measures may be attempted, they are unlikely to provide adequate symptom relief. The artificial urinary sphincter represents the gold standard treatment for this condition and should be pursued as the next best step after appropriate evaluation.
