Study on 730 pregnant women with oligohydramnios, among 10,663 normal pregnancies at National Obstetrics and Gynecology Hospital in 2002. In 250 pregnant women with oligohydramnios there were 66.4% had cesarian section, 31.6% had normal childbirth and 4% had an extra option under childbirth, the amniotic fluid volume depended on gestational age, from 30 weeks, amniotic fluid volume decreased with the speed about 33% per one week. Amniotic fluid volume associated with the condition on health of fetus. Now using the ultrasound to evaluate the amniotic fluid volume by two techniques: the maximal vertical pocket and the amniotic fluid index

Sirenomelia, also known as the mermaid syndrome, is a rare and usually lethal congenital malformation of uncertain etiology. It is characterized by fusion of the lower limbs and commonly associated with severe urogenital and gastrointestinal malformations. Early antenatal sonogram allows for earlier, and less traumatic termination of pregnancy, but usually it is impared by severe oligohydramnios related to bilateral renal agenesis. We diagnosed a sirenomelia with severe oligohydramnios at early second trimester after amnioinfusion and terminated. We report a case with a brief review of the literature.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossae. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present a case of fetal bilateral renal agenesis diagnosed by ultrasonography after amnioinfusion at 19 weeks gestation.

Twin-twin transfusion syndrome is attributed to an unbalanced blood flow between the donor and the recipient twin, but the exact pathophysiology remains incompletely understood. Despite active prenatal management, fetal twin-twin transfusion syndrome is still associated with a substantial residual perinatal mortality and morbidity. The donor twin progressively becomes anemic, growth restricted, oliguric and has oligohydramnios, where as the recipient becomes plethoric, polyuric and has polyhydramnios and in the most severe cases develops cardiomegaly, congestive heart failure and hypertension. We report a case of severe systemic hypertension developed in recipient twin.

Fetal bilateral renal agenesis is a lethal congenital anomaly characterized by bilateral pulmonary hypoplasia, deformities and death due to severe oligohydramnios. This syndrome is associated with malformations of genitourinary tract, cardiovascular system, vertebral bodies or imperforated anus in more than half of the affected individuals. An early and reliable prenatal diagnosis is extremely important because it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, empty renal fossae. But poor sonographic resolution of severe oligohydramnios makes it difficult to diagnose the disease. We present a case of bilateral renal agenesis diagnosed at the 32nd weeks gestation by using color doppler and "lying down" adrenal sign.

The optimal management in pregnancies complicated isolated oligohydramnios between 34(+0) and 36(+6) weeks of gestation is not established yet. Although previous studies reported that increased risks of adverse perinatal outcomes were observed in pregnancies with oligohydramnios, it is notable that these studies include cases with maternal or fetal complications such as hypertensive disorders or fetal growth restriction. Therefore, it remains unclear that the increased adverse perinatal outcomes from oligohydramnios are caused from oligohydramnios itself or from maternal or fetal complications. Meanwhile, recent evidences demonstrated that neonates born at late preterm are also at increased risks for prematurity related complications such as respiratory distress syndrome, intraventricular hemorrhage, neonatal hypoglycemia, necrotizing enterocolitis and cerebral palsy as well compared with term neonates. With this background, this article was aimed to review recent literatures on the optimal management in pregnancies with isolated oligohydramnios between 34(+0) and 36+6 weeks of gestation and to present the results from survey of obstetricians in our country on this topic.

A balanced insertion of a parent may produce normal or carrier offsprings, spontaneous abortions, and chromosomally unbalanced offsprings. This is a rare report of duplication of chromosome 10q22->q24 which has arisen through the segregation of a balanced direct insertion. The partial trisomy 10q is a specific syndrome of mental retardation and malformation characterized by psychomotor delay, growth restriction, distinctive dysmorphic appearances, and, in some cases, cardiac, renal, and ocular abnormalities. We have experienced a case of partial trisomy 10q from maternal balanced insertion, which was prenatally showed severe fetal growth restriction and oligohydramnios, and present it with a brief review of literatures.

OBJECTIVE: To quantify the improvement in ultrasonographic fetal imaging following diagnostic amnioinfusion for the indication of unexplained midtrimester oligohydramnios. METHODS: Eight patients were referred for unexplained midtrimester oligohydramnios were retrospectively reviewed. Videotapes of those undergoing diagnostic antenatal amnioinfusion were analyzed for quality of visualiztion of routinely imaged structures before and after the infusion procedure. And genetic amniocentesis was performed in all patients. RESULTS: The overall rate of adequate visualization of fetal structures improved from 64.1% to 95.2% (P=0.008). In most cases we were able to achieve a definitive diagnosis. CONCLUSION: Diagnostic amnioinfusion can facilitate fetal imaging and increase diagnostic precision in the setting of unexplained severe oligohydramnios.
