Vaginal births after Caesarean section (VBAC) are well-accepted procedures when pregnant women do not have any contra-indications. The possibilities of the uterine dehisence and rupture during VBAC should always be considered. This occurrence is usually related to the previous scar tissue and subsequent risk is acceptable. Nevertheless, rupture that occurs ...

The oxytocin-like peptide of most Australian marsupials is mesotocin, which differs from oxytocin by a single amino acid. This substitution has no functional significance as both peptides have equivalent affinity for and biological activity on the marsupial oxytocin-like receptor. A role for mesotocin in marsupial parturition has been demonstrated in ...

Evaluation of the fluid flow pattern in a non-pregnant uterus is important for understanding embryo transport in the uterus. Fertilization occurs in the fallopian tube and the embryo (fertilized ovum) enters the uterine cavity within 3 days of ovulation. In the uterus, the embryo is conveyed by the uterine fluid ...
Banerjee N - - 1999
The role of a uterine septum, and thus, metroplasty in an infertile woman is a debatable issue. A rare complication of fetal malpresentation and impaction in the uterine cavity due to undiagnosed uterine septum in a 24-year-old primigravida who conceived after 3 years of primary infertility is reported. This case ...
Elsayegh A - - 1998
Pregnancy in the rudimentary horn is rare and represents a form of ectopic gestation. Despite advances in ultrasound, prenatal diagnosis remains elusive, with confirmatory diagnosis being made at laparotomy. Because of variable muscular constitution of the wall of the rudimentary horn, pregnancy can be accommodated until late in pregnancy, when ...
Tamada H - - 1998
The fetuses released into the abdominal cavity by uterine incision escape from most physical influences of the uterus. This study examined whether these fetuses require progesterone actions for survival during late pregnancy in rats. A longitudinal incision in one uterine horn (with the other horn intact) together with bilateral ovariectomy ...
Riemer R K - - 1998
The uterus is unique among smooth muscular organs in that, during pregnancy, it undergoes profound, largely reversible, changes orchestrated by the ovarian hormones. These changes facilitate uterine adaptation to the stretch induced by the growing fetus such that a state of myometrial contractile quiescence can be maintained. This quiescent state ...
Kuroda T - - 1998
BACKGROUND/PURPOSE: To develop practical and less invasive techniques for fetal endoscopic surgery, new methods of lifting the uterine wall to allow fetal surgery without maternal laparotomy were developed and assessed.
