Our objective was to determine the relationships between a trans-obturator sling and anatomic structures within the obturator region. The obturator regions of six cadavers were dissected and distances from the mid-point of the ischiopubic ramus to the muscles, nerves, and vessels of the region were measured. A trans-obturator sling was placed and distances from the device to the same anatomic structures were determined. Four additional cadavers were dissected to determine the device route of passage. The obturator canal is on average 4.4 cm from the midpoint of the ischiopubic rami. The trans-obturator sling passes on average 2.4 cm inferior-medial to the obturator canal. The anterior and posterior divisions of the obturator nerve are on average 3.4 and 2.8 cm, respectively, from a passed trans-obturator device. The device passed on average 1.1 cm from the most medial branch of the obturator vessels. Vascular and nerve structures are within 1-3 cm of the path of any device passed through the obturator foramen. A trans-obturator sling risks injury to these structures, although the small caliber of the vessels and the confined space in which they would bleed make the consequences of injury uncertain.
