INTRODUCTION: At the end of pregnancy, the amniotic fluid (AF) depends basically on renal function, corresponding to fetal urine. Changes in AF, especially oligohydramnios, are reported in association with fetal hydronephrosis (FH). The experimental model using adriamycin in pregnant female rats has a teratogenic effect and has been classically employed ...

Fetal surveillance significantly reduces the incidence of fetal loss, perinatal morbidity and maternal distress. Obstetricians traditionally classify pregnancies as 'low' or 'high risk' and apply various methods of fetal surveillance in the latter group. However, the majority of stillbirths now occur in 'low-risk' women. This seemingly anomalous observation emphasises the ...

PURPOSE: Gastrointestinal (GI) dysmotility occurs frequently in full-term infants with gastroschisis (GS). Although controversial, preterm delivery of infants with GS has been advocated to prevent the development of GI dysmotility, and understanding the etiology of gestational-related bowel injury may lead to prenatal therapies. Using a fetal rabbit model, the authors ...
