[Utilization of a pedicled labial flap, single or double face, for the management of post-obstetric urethral damage]

Reported here is our experience with a single or double-face new procedure using a pedicled labial flap for urethral reconstruction in patients treated for extensive urethral damage after obstetrical injury. Between January 1992 to July 1997, 56 cases of urethral damage on African female patients, with an average age of 18 years old, were treated by pedicled labial urethroplasty. This procedure was done by using a single or double-face pedicled flap obtained from the major or minor labia. The flap was then introduced as in a tunnel beneath the vaginal epithelium reaching the damaged urethra. A variety of techniques were proposed: patch for sufficient lengthening (27 cases), tubularized flap allowing complete reconstruction of the urethra (18 cases) and the double-face urethroplasty (11 cases). Good quality urine continence was obtained by using the sub urethral Martius'sling procedure. In 11 cases, we combined the treatment with a colposuspension procedure. The average follow-up was 23 months (ranging from 5 to 47 months). The global success was 82% (52 patients treated). Recovery of normal miction and absence of urinary leak was obtained in 36 cases (69%). While 7 moderate failures occurred (13%), 9 cases were considered complete failures (17%). In view of the high success rate, we consider that the one-stage procedure by the use of a single or double face pedicled labial flap is a choice treatment and highly suitable for the management of extensive urethral cervical damage after obstetrical injury.
