This is our last episode for 2023! A podcast family member reached out to me notifying me of a thread on social media discussing ultrasound measurements of “lower uterine segment thickness” (LUST) for TOLAC candidates. I consider myself pretty social media friendly, but was unaware of this comment thread. Should we be measuring lower uterine segment thickness in the late 3rd trimester as a discriminatory tool for TOLAC approval/denial? Is this evidence-based? Where did this concept originate? Is this supported by the ACOG? The answer to all of this is both YES and NO. We will explain in this episode.
