Study information

Primary study designObservational
Study designObservational prospective cohort study
Secondary study designCohort study
Scientific titleScar Evaluation after Caesarean by Ultrasound Registry
Study acronymSECURE
Study objectivesThe primary hypothesis is that an association exists between the presence of a niche and abnormal uterine bleeding in women who had a previous caesarean section.
Ethics approval(s)Ethics approval received from the medical ethics committee of Vrije University Medical Centre (METc VUmc) on the 4th September 2007 (ref: 2007/126).
Health condition(s) or problem(s) studiedAbnormal uterine bleeding, uterine rupture, caesarean section
InterventionGel instillation sonohysterography is performed 6 to 12 months after caesarean section to detect a niche. Women are asked to fill in a questionnaire and keep a diary card to discover abnormal uterine bleeding.

In case of subsequent pregnancy, transvaginal ultrasound is performed to detect the presence of a niche and measure the thinnest zone of the lower uterus segment.
Intervention typeOther
Primary outcome measure(s)

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

Key secondary outcome measure(s)

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
