Single-layer versus double-layer uterine closure after cesarean and myometrial thickness
Official title: Effects of Single-Layer Versus Double-Layer Cesarean Scar Repair on Myometrial Thickness and Associated Clinical Outcomes
Run by Ankara City Hospital Bilkent · NCT07323355 · Data updated 2026-11-12
This trial tests whether closing the uterus with one layer or two layers during cesarean leads to thicker, healthier scar tissue in women having a cesarean delivery.

Is this trial a fit for you?
✓Likely a good fit
Women aged 18–44 who are delivering by cesarean at the study hospital, are clinically healthy on routine preoperative tests, and meet the listed inclusion criteria.
✕Probably not a fit
Women with chronic illnesses, suspected or confirmed placenta previa/accreta, anterior wall myomas, nonstandard uterine incisions, predicted obstetric hemorrhage, or those who will not deliver at the study site are unlikely to benefit from participation.

What this trial studies
This interventional trial compares single-layer and double-layer uterine closure techniques in women undergoing cesarean delivery at Ankara Bilkent City Hospital. Eligible participants receive one of the two closure methods during their cesarean operation and are followed after surgery. Myometrial thickness and scar characteristics will be measured using postoperative ultrasound and clinical follow-up. The protocol excludes women with chronic systemic disease, placenta previa/accreta, anterior uterine fibroids, nonstandard uterine incisions, or predicted obstetric hemorrhage.
Why it matters
Potential benefit: If one closure method produces reliably thicker myometrium and fewer scar defects, it could reduce postmenstrual symptoms and lower the risk of serious future complications like uterine rupture or placenta accreta.
How similar studies have gone: Previous comparisons of single- versus double-layer uterine closure have shown mixed results and there is no clear consensus on which technique best prevents scar defects.
