Answer

To avoid injuring the ureters, the surgeon must always be aware of the location of these structures in the retroperitoneum. The ureter is easily identified at the pelvic brim where it crosses over the external iliac artery. It is visible as a white structure that, on gentle compression, demonstrates characteristic propulsive movement.
