BACKGROUND: Female urethral injury is rare, and there is no accepted standard approach for the repair of urethral strictures.

OBJECTIVE: To evaluate the efficacy of transpubic access using pedicle tubularized labial urethroplasty for urethral reconstruction in female patients with urethral obliterative strictures and urethrovaginal fistulas.

DESIGN, SETTING, AND PARTICIPANTS: Between January 1996 and December 2006, eight cases of female urethral strictures associated with urethrovaginal fistulas were treated using pedicle labial skin flaps.

INTERVENTIONS: A flap of approximately 3x3.5x3cm of the labia minora or majora with its vascular pedicle was tubularized over an 18-22 Fr fenestrated silicone stent to create a neourethra. This technique was used in five women. Two flaps, approximately 1.5-3.5 cm, were taken from bilateral labia minora or majora and were pieced together to create a neourethra. This technique was used in three patients.

MEASUREMENTS: We performed voiding cystourethrography and uroflowmetry to assess postoperative results.

RESULTS AND LIMITATIONS: The patients were followed up for 10-118 mo (mean 48.25 mo) after the procedure. There were no postoperative complications. Two patients complained of dysuria, which resolved spontaneously after 2 wk. One patient experienced stress incontinence that resolved after 4 wk. At 3-mo follow-up, one patient complained of difficulty voiding; the urinary peak flow was 13 ml/s, and the patient was treated successfully with urethral dilation. All other patients had normal micturition following catheter removal.

CONCLUSIONS: Pedicle labial urethroplasty is a reliable technique for the repair of extensive urethral damage, and a transpubic surgical approach provides wide and excellent exposure for the management of complex obliterative urethral strictures and urethrovaginal fistulas secondary to pelvic fracture.
