NCT ID NCT02201732
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study compares hysteroscopy (using a tiny camera) to standard curettage (scraping) for removing leftover tissue after an incomplete miscarriage. It involved 577 women under 45 who wanted to get pregnant again. The main goal was to see which procedure leads to more successful pregnancies beyond 22 weeks.
