Two-dimensional Ultrasonography of Pelvic Floor and Anorectal Anatomy

  • Felix Aigner
  • Hannes Gruber


This chapter should help to clarify the anatomical relationships and complex anorectal topography that can be clearly visualized by modern ultrasound techniques and should be recognized by the pelvic surgeon. The pelvic floor forms the supportive and caudal border of the abdominal cavity. Previous anatomical studies have demonstrated that the pelvic connective tissue can be divided into three compartments: anterior, middle, and posterior. This chapter is dedicated to the posterior compartment and reflects the supportive function of the pelvic floor muscle systems as well as its impact on continence function and defecation.
