Design outcomes

Primary

Measure	Time frame
1. A well circumscribed anatomical niche classification. The niches will be measured by ultrasound 6 - 12 months after caesarean section 2. A difference in uterine bleeding pattern between women with different niche types (based on the classification), with a follow-up of the bleeding pattern for 5 years after caesarean section	—

Secondary

Measure	Time frame
1. To demonstrate a relation between niche and Lower Uterine Segment (LUS) thickness in case of a subsequent pregnancy. The LUS will be measured between 16 and 20 weeks? gestation, and between 36 and 38 weeks? gestation 2. To demonstrate an association between: 2.1. Niche and (in)complete uterine rupture 2.2. LUS thickness and (in)complete uterine rupture To identify an (in)complete rupture, the course of the pregnancy will be recorded	—
