title: Anatomical risks of transobturator suburethral tape in the treatment of female stress urinary incontinence.
abstract: BACKGROUND
  The objective of this study was to define the anatomical structures crossed by transobturator tape.
  
  
  METHODS
  Ten fresh, female anatomical subjects aged 74 to 89 years.
  
  
  METHODS
  Transobturator tape was inserted by outside-in way. The position of the tape was verified by perineal and abdominal dissection.
  
  
  RESULTS
  Transobturator tape has a transverse course. It crosses the adductor muscles close to their pubic insertion and passes over the inferior border of the obturator foramen by crossing the obturator membrane, before reaching the middle plane of the perineum after having crossed the obturator internus muscle. The tape passes above the internal pudendal pedicle and then under the levator ani muscle, under the tendinous arch of the pelvic fascia and continues in the middle third of the urethrovaginal septum. It avoids femoral and obturator vessels in the thigh and pudendal vessels in the perineum.
  
  
  CONCLUSIONS
  The anatomical course of transobturator tape shows that the anatomical structures crossed by the tape are muscle and fascia and, when the technique is performed correctly, no major neurovascular structures are in contact with the tape.
