The aim of this study was to investigate the course of the transobturator posterior anal sling and its relationship to anatomical structures.

The transobturator anal sling procedure was performed in four fresh-frozen pelvises. The pelvises were dissected and the structures adjacent to the sling and the course of the sling were identified and measurements obtained.
The transobturator posterior anal sling travels mostly in the avascular area of the ischiorectal fossa and posterior to the puborectalis muscle as intended.
