Clean intermittent self-catheterization after urethrotomy for recurrent urethral strictures

Area of Science:

• Urology
• Surgical Innovation
• Patient Management

Background:

• Endoscopic optical urethrotomy is a primary treatment for urethral stricture but has a high recurrence rate.
• Preventing scar shrinkage post-urethrotomy is crucial for long-term success.
• Recurrent urethral stricture necessitates effective management strategies.

Purpose of the Study:

• To compare the efficacy of clean intermittent self-catheterization (CIC) for 6 versus 12 months following internal urethrotomy in patients with recurrent urethral stricture.
• To evaluate the impact of CIC duration on recurrence rates and uroflowmetry parameters.
• To assess the feasibility and complications associated with CIC in this patient group.

Main Methods:

• A controlled study involving 49 patients with recurrent urethral stricture, randomized to 6 or 12 months of CIC post-urethrotomy.
• Uroflowmetry assessments were performed pre- and post-urethrotomy, with follow-ups at 3, 6, 9, and 12 months.
• Recurrence was defined as the need for re-treatment.

Main Results:

• No significant difference in recurrence rates was observed between the 6-month and 12-month CIC groups.
• Patients who ceased CIC at 6 months showed a significantly lower maximum flow rate at 12 months compared to those continuing.
• CIC was easily learned by most patients, with complications including asymptomatic bacteriuria and symptomatic urinary infections.

Conclusions:

• Clean intermittent self-catheterization (CIC) is a feasible and satisfactory method for managing recurrent urethral stricture post-urethrotomy.
• Longer durations of CIC may help preserve maximum flow rate, although optimal duration remains undetermined.
• CIC offers a viable alternative to regular bouginage for selected patients.
