Could a simple ultrasound replace an invasive scope for Post-Surgery uterine checks?

This study looks at two ways to examine the uterine cavity after women have had hysteroscopic surgery for conditions like polyps, fibroids, or a uterine septum. One method is a non-invasive 3D ultrasound; the other is an office hysteroscopy, which involves inserting a small camera into the uterus. The goal is to see if the ultrasound is accurate enough to replace the more invasive procedure, potentially reducing pain and cost for patients.
