The ureter is the medial margin of a broad ligament pocket or hernia in up to 100% of large upper broad ligament defects.  Medial deviation of the ureter occurs in at least 25% of these.  This does not include small pockets near the uterosacral ligaments.

These examples show right broad ligament pockets or hernias in two patients.  The ureter is the medial margin in both examples.  The ureter is in the mid-broad ligament in the first example.  There is medial displacement of the right ureter to the uterosacral ligament in the second example.  The left ureter is in a normal position in that example.
