Purpose:
Urethral strictures in females are uncommon, and treatment options and outcome are not well-defined with scanty reports. We describe a new method of urethroplasty for the repair of female urethral stricture.
Materials And Methods:
Three 60-year-old females, each with a history of recurrent urinary tract infections and obstructive voiding symptoms due to urethral stricture, underwent urethroplasty with a dorsal vaginal or buccal mucosal graft. The dorsal aspect of the distal urethra was dissected from the surrounding tissue through a suprameatal incision and the urethral wall was incised through the stricture at the 12 o'clock position. A 1.5 cm wide free graft was harvested from the vaginal wall or buccal mucosa in 1 case, and the mucosal surface was placed upon the urethral lumen and sutured with a running 5-zero polyglactin suture to the open urethra. Indwelling 18Fr urethral and 16Fr suprapubic catheters were left in place for 2 and 3 weeks, respectively.
Results:
No additional treatment was required during the 1, 8 and 27 months of followup. All patients had normal micturition following catheter removal.
Conclusions:
Dorsal graft urethroplasty is feasible and effective for the correction of persistent female urethral stricture.
