RESUMO

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.

RESUMO

The posterior intravaginal sling is a new tension-free needle suspension technique. It is used for the treatment of middle compartment (vaginal vault or uterine) prolapse. The Prolene sling suspends the vagina at the upper border of level II support as described by DeLancey (Am J Obstet Gynecol 166:1717, 1992). Human cadaveric dissections were undertaken to explore the pertinent anatomy that is involved when using this blind needle technique. Pre-dissected cadaveric material was used to obtain didactic illustrations of the anatomy of the procedure. Description of the surgical technique using anatomical landmarks and relative distances of the needle to these landmarks will improve the surgeon's visual understanding of the procedure. The measurements obtained demonstrate that the needle stays at a minimal distance of 4 cm away from the major (pudendal) vessels that could potentially cause life-threatening haemorrhage.
