Direct visual internal urethrotomy for isolated, post-urethroplasty strictures: a retrospective analysis

Area of Science:

• Urology
• Surgical Innovation

Background:

• Urethroplasty is a common treatment for male urethral strictures.
• Data on managing recurrent strictures post-urethroplasty is limited.

Purpose of the Study:

• To evaluate direct visual internal urethrotomy (DVIU) for isolated, recurrent strictures following urethroplasty.
• To assess the success rate and identify factors associated with DVIU outcomes in this patient group.

Main Methods:

• Retrospective review of male patients who underwent urethroplasty (1999-2013) and developed recurrent strictures treated with DVIU.
• Success defined as absence of symptoms and need for further intervention.
• Comparative analysis of patient and stricture characteristics.

Main Results:

• 16% of urethroplasty patients (64/401) experienced recurrence.
• 37 patients underwent 50 DVIU procedures for recurrent strictures at the urethroplasty site.
• Overall success rate for DVIU was 40% (17/43), with single DVIU success in 35% (13/37).
• Success was not associated with patient age, stricture characteristics, or prior treatments.

Conclusions:

• Direct visual internal urethrotomy (DVIU) can be a viable, minimally invasive option for recurrent urethral strictures after urethroplasty.
• This approach successfully spared approximately 40% of patients from additional interventions.
