Q

What are some techniques for measuring a retroflexed uterus?

A
  1. Select more tools
  2. Curved caliper
  3. Trace the length of the uterus from the fundus to the external OS of the cervix

Q

What can be said about measuring a retroflexed uterus?

A

Endometrium might be difficult to assess as the uterus will rotate as it flexes resulting in a wider than normal endometrial appearance
