In this chapter, we will review the pertinent anatomy, focusing on the 6 structures that should be considered during the repair and surgical techniques to promote restoration on normal anatomy and function. Key concepts include a tension-free repair, meticulous hemostasis, and postoperative bowel management. *Department Obstetrics and Gynecology †Fellow in Female Pelvic Medicine and Reconstructive Surgery, University of Michigan, Women's Hospital, Ann Arbor, Michigan Correspondence: John O.
