Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This study compares two types of ultrasound—2D and 3D—with and without saline infusion, to see which best detects defects in the scar from a previous C-section. Researchers will enroll 100 women aged 20-45 who have had at least one C-section. The goal is to find the most accurate imaging method and understand how scar size relates to symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could identify the most accurate imaging method for detecting cesarean scar defects, potentially improving diagnosis and treatment planning.
What could go wrong
This is a small, single-center diagnostic study, so results may not apply broadly. The comparison may not reveal a clear winner, and the clinical impact depends on linking defects to symptoms.
