Electronic poster abstractsMethods: A total of 657 women with16 weeks -41 weeks of normal gestation were enrolled in the study who received routine obstetric ultrasound in our hospital from September 2008 to March 2015. The volume and blood flow parameters of kidney and fetal growth parameters were measured by two and three dimensional ultrasound. The relations between various parameters of kidney with gestational age, growth indexes were analysed. Results: Renal volume was linearly associated with gestational age, and renal volume = -7.01 + 0.554 × gestational age (16 weeks≤ gestational age≤ 41 weeks).Fetal volume was significantly related to growth indexes, and the correlation with height, weight before pregnancy was not obvious.PSV, EDV and TAMXV of renal artery increased with gestational age; S/D, PI and RI decreased with gestational age. Conclusions: The volume of normal fetal kidney increases gradually along with the gestational age, a linear correlation is between them.The size of normal fetal kidney is associated with fetal growth itself, but is not affected by maternal height, weight before pregnancy. With the increase of gestational age, the blood flow of fetal renal artery speeds, resistance drops and blood flow perfusion increases. Objectives: Evidence suggests that an adverse environment during intrauterine life and early childhood is a risk factor for a wide spectrum of disorders later in life, including cardiovascular and renal disease. We aim to evaluate the role of intrauterine growth restriction in kidney disease in adulthood. Methods: An electronic search was conducted through October 2016 in the CENTRAL, LILACS, MEDLINE, and EMBASE databases. The inclusion criteria were studies comparing renal function in adulthood with birth weight using transversal or longitudinal designs. The reviewers analysed the inclusion criteria and risk bias and extracted data from the included studies. Twenty articles met the inclusion criteria for the systematic review, and 13 were included in the meta-analysis. Results: There was an increased risk of developing end-stage renal disease (risk ratio (RR) 1.31, 95% confidence interval (CI): 1.17, 1.47), a lower glomerular filtration rate (ml/min) (mean difference (MD) -7.14; 95% CI: -12.12, -2.16), microalbuminuria (RR 1.40; 95% CI: 1.28, 1.52) and a small increase in the albumin/creatinine ratio (MD 0.46; 95% CI: 0.03, 0.90) in the low birth weight group. Conclusions: Our results suggest that low birth weight is related to renal dysfunction in adulthood. Objectives: Although an absent or reversed a-wave in ductus venosus (DV-RAV) is reported to be the terminal finding of fetal growth restriction (FGR), we have seen a DV-RAV that disappears in a short span of time, causing us to reconsider the mechanism of DV-RAV in FGR. EP14.08Methods: This was a retrospective study of 499 FGR cases, including 14 with DV-RAV. Transabdominal amnioinfusion (AI) was performed when oligohydramnios was severe and/or a sign of cord compression was detected. DV-RAV that disappeared in a sho...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
