Technique and results of urethroplasty for female stricture disease

Purpose: Urethral stricture disease in females is uncommon and is often treated with repeat dilation or internal urethrotomies. Various surgical techniques to repair strictures have been described with successful results. However, these techniques are cumbersome to use. The vaginal inlay flap is simple and easy to learn. To our knowledge this is the first report of its use and clinical results in a series of patients from 2 institutions. Materials and Methods: Eight symptomatic women with a history of traumatic or difficult catheterization, a history of at least 1 urethral dilation or urethrotomy and difficult or a failed attempt at catheter placement underwent urethroplasty. The technique consisted of incising the posterior aspect of the stricture and advancing a vaginal inlay flap. A retrospective chart review was performed. Results: Followup was 1 to 9 years. All patients had subjective relief of symptoms and could easily catheterize with a 14Fr catheter. Average caliber of the urethra increased from 9.25Fr to 16.5Fr and post-void residual urine decreased from 130 to 15 cc. One patient with a hypotonic bladder was in retention, which resolved during 3 months. One patient underwent repeat dilation once 3 weeks after the primary procedure with no recurrence. No patient had stress urinary incontinence. There were no immediate or delayed serious complications. Conclusions: Urethral stricture disease in females is an uncommon entity that can cause voiding symptoms, recurrent infections, retention and renal impairment. This method of surgical repair offers a durable result and has a low incidence of complications.
