title: Anatomical variability in the trajectory of the inside-out transobturator vaginal tape technique (TVT-O).
abstract: An experimental surgical study on human cadavers was undertaken to assess variability in the trajectory followed by the needle during application of the inside-out transobturator tape suspension (TVT-O) technique. The TVT-O surgical procedures were performed on six fresh female cadavers according to the standard recommended operative protocol. Subsequent anatomical dissection revealed that the needle had perforated the obturator membrane at a distance of 0.7 to 2.0 cm from the needle to the obturator canal. It subsequently followed a variable course passing at 0.5 to 2.0 cm from the anterior branch of the obturator nerve and 0.1 to 1.4 cm from the posterior branch. We conclude from this anatomical study that the TVT-O trajectory is subject to wider variability than was originally postulated.
