title: Anatomic relation between single-incision slings and the obturator vessels.
abstract: The risk of arterial vascular injury within the retropubic space is a potentially life-threatening complication associated with mid-urethral sling placement for the treatment of female stress urinary incontinence. To determine the relationship between the major blood vessels and a single incision sling, these slings were placed in 12 fresh female cadavers. Following the insertion of each sling, the retropubic space was dissected and sling placement was observed relative to the obturator neurovascular bundle bilaterally. The distance between the most distal aspect of each sling arm, or the point of anchoring, was measured from the most medial aspect of the obturator vessels bilaterally. The mean distance between each sling arm and the medial portion of the obturator vessels was an average of 3.4 cm (range 2.0-6.0 cm) in 24 observations. Placement of the single incision sling may have a lower risk of injuring major vessels within the retropubic space compared to full-length mid-urethral slings.
