Transpubic Access Using Pedicle Tubularized Labial Urethroplasty for the Treatment of Female Urethral Strictures Associated with Urethrovaginal Fistulas Secondary to Pelvic Fracture

BackgroundFemale urethral injury is rare, and there is no accepted standard approach for the repair of urethral strictures.ObjectiveTo 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 participantsBetween January 1996 and December 2006, eight cases of female urethral strictures associated with urethrovaginal fistulas were treated using pedicle labial skin flaps.InterventionsA flap of approximately 3 × 3.5 × 3 cm 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.MeasurementsWe performed voiding cystourethrography and uroflowmetry to assess postoperative results.Results and limitationsThe 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.ConclusionsPedicle 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.
