Acute kidney injury (AKI) is costly and is associated with increased mortality and morbidity. An understanding of the renal physiologic changes that occur during pregnancy is essential for proper evaluation, diagnosis, and management of AKI. As in the general population, AKI can occur from prerenal, intrinsic, and post-renal causes. Major causes of pre-renal azotemia include hyperemesis gravidarum and uterine hemorrhage in the setting of placental abruption. Intrinsic etiologies include infections from acute pyelonephritis and septic abortion, bilateral cortical necrosis, and acute tubular necrosis. Particular attention should be paid to specific conditions that lead to AKI during the second and third trimesters, such as preeclampsia, HELLP syndrome, acute fatty liver of pregnancy, and TTP-HUS. For each of these disorders, delivery of the fetus is the recommended therapeutic option, with additional therapies indicated for each specific disease entity. An understanding of the various etiologies of AKI in the pregnant patient is key to the appropriate clinical management, prevention of adverse maternal outcomes, and safe delivery of the fetus. In pregnant women with pre-existing kidney disease, the degree of renal dysfunction is the major determining factor of pregnancy outcomes, which may further be complicated by a prior history of hypertension. © 2012 Dustri-Verlag Dr. K.

Hypertensive disorders in pregnancy are one of the leading causes of maternal death in the world and one of the major causes of perinatal mortality. The incidence of hypertensive disorders in pregnancy is 8%-15%. Significant changes of biochemical parameters in cases of hypertensive disorders in pregnancy are increased levels of blood glucose, urea, creatinine, uric acid (hyperuricemia), transaminases, and LDH. The most increased is the level of proteinuria. Bad laboratory results and the intensification of clinical signs, with multiorgan dysfunction, are indications for termination of pregnancy. © 2013 Informa Healthcare USA, Inc.

Objective - Ultrasound examination for each and every pregnancy is being accepted as a standard practice worldwide, and prenatal ultrasound diagnosis of congenital heart disease (CHD) is improving due to both staff education and ultrasound equipment modernization. The objective of this study was to estimate the value and accuracy of fetal echocardiography for diagnosis of fetal CHD in a large tertiary referral center for obstetrics and gynecology. Methods - This study was based on a prospective follow-up of 27,051 consecutive patients at the Institute of Ob/Gyn, Belgrade, during 1999-2003. Out of this population a total of 517 (1.9%) patients were selected for fetal echocardiography. The final diagnosis of congenital heart disease was confirmed or rejected on the basis of autopsy and histopathological findings, for the dead fetuses and newborns, or on the basis of neonatal echocardiography (followed by surgery/invasive diagnostic procedure), for the living neonates. Results - From the total population analyzed, there was 71 gravida (0.26%) with congenital fetal heart disease. In that study group, the most frequent cardiac anomalies were complex congenital heart diseases. Analyzing the outcome, there were 67.6% cases with fetal CHD who delivered live neonates. Out of the 73 fetuses/neonates with CHD, abnormal karyotype was detected in only 9 cases. The parameters of the diagnostic value of fetal echocardiography were as follows: sensitivity 94.4%, specificity 99.8%, positive predictive value 98.5%, negative predictive value 99.1%, and overall diagnostic accuracy 99.0%. Conclusion - Fetal echocardiography has a very high diagnostic accuracy, commending referral of suspected patients to large tertiary referral centers. © 2007 Controversies in Obstetrics and Gynecology, Polish Society of Perinatal Medicine, the International Society of Reproductive Medicine, the World Foundation for Medical Studies in Female Health and the Center for the Study of Cryopreservation of Oocytes and Spermatozoa.
