Discussion on the Lower Uterine Segment in Labour

Prediction of scar integrity and vaginal birth after caesarean delivery.

A statistically significant association with uterine rupture during a trial of labour after caesarean delivery was found in at least two studies for the following variables: inter-delivery interval (higher risk with short interval), birth weight (higher risk if 4000 g or over), induction of labour (higher risk), oxytocin dose (higher risk with higher doses), and previous vaginal delivery (lower...

Rupture of the transverse uterine scar after lower segment caesarean section.

THE lengthening list of indications for Caesarean section makes the management of subsequent deliveries a problem which confronts the obstetrician with ever-increasing frequency. Where the original Caesarean section was performed for a non-recurrent indication, subsequent vaginal delivery may reasonably be expected, and it is customary to allow such patients to go into labour. Even where electi...

Posterior Uterine Rupture Causing Fetal Expulsion into the Abdominal Cavity: A Rare Case of Neonatal Survival

Introduction. Uterine rupture is a potentially catastrophic complication of vaginal birth after caesarean section. We describe the sixth case of posterior uterine rupture, with intact lower segment scar, and the first neonatal survival after expulsion into the abdominal cavity with posterior rupture. Case Presentation. A multiparous woman underwent prostaglandin induction of labour for postmatu...

Assessment of Myometrial Concentrations of Oestrogen and Progesterone Receptors in the Lower Uterine Segment of Full-Term Pregnancies in Presence or Absence of Labour

OBJECTIVE To assess the concentration of progesterone (PRs) and oestrogen (ORs) receptors of myometrium of full-term pregnant women in the myometrium of lower segment of the uterus in relationship with presence or absence of labour. METHODS This was a cross-sectional prospective study with 21 pregnant women, being 6 in labour (Group I) and 15 without labour (Group II). The biopsy of myometriu...
