Basic Anatomy and Principles of Surgery in Gynaecologic Oncology

Pelvic can be divided into a true and false pelvis. The dividing

border between the true and false pelvis is an oblique line that

extends from the sacral promontory along the anterior aspect of S1

to the symphysis pubis. True pelvis is below this line and is smaller

than the false pelvis. The reproductive organs, bladder, pelvic

ureters, small bowel loops and rectum lie within the true pelvis.
