Abstract
BACKGROUND With the increasing rate of high-risk pregnancies, there is an increased need for early evaluation of at-risk fetuses. Fetal ultrasound imaging has become a pivotal part of this evaluation. METHODS To evaluate the role played by a fetal ultrasound clinic in promoting comprehensive perinatal care of patients with high-risk pregnancies, we retrospectively analyzed the indications and findings of fetal scans and the outcomes of the examined fetuses collected over the past 7 years (2014-2020) by our institute, which is reorganized as a perinatal medical center. RESULTS During the study period, we conducted 345 fetal scans in high-risk pregnancy cases. Of these, 158 cases (46%) were referrals from other institutes. Eighty-nine neonates were admitted to our neonatal intensive care unit (NICU) after being evaluated, of which 10 neonates underwent surgery during their NICU stays. Thirty-nine pregnant women were referred to other tertiary care hospitals mainly due to fetal diagnoses with complex cardiac anomalies. Fourteen cases resulted in intrauterine fetal death or artificial abortion. CONCLUSIONS Fetal ultrasound clinics have established their role in facilitating sophisticated regional perinatal care via multidisciplinary and inter-facility cooperation for high-risk pregnancy cases. In addition, providing psychological support and counseling for pregnant women whose fetuses are diagnosed with severe congenital anomalies should not be neglected.

Abstract
OBJECTIVE To assess the performance of a basic mid-trimester fetal ultrasound scan protocol for the diagnosis of congenital anomalies by calculating its accuracy, sensitivity, and specificity. METHODS This longitudinal cohort study involved singleton pregnant women recruited at the mid-trimester fetal ultrasound scan through the postnatal evaluation of congenital anomalies. Pregnant women who underwent a routine mid-trimester ultrasound scan for fetal abnormalities at 20-24 weeks of gestation were enrolled in this study. After childbirth, we searched their medical records on gestational outcomes and neonatal examination records, as well as complementary medical examinations, to assess the ultrasound performance in diagnosing congenital malformations. RESULTS We included 967 pregnant women in the study population, and prenatal ultrasound scans detected congenital abnormalities in 67 fetuses (6.9%). Among newborns, 54 (5.6%) were postnatally diagnosed with malformations. The overall sensitivity and specificity of the mid-trimester ultrasound scan for congenital malformation detection were 61.1% and 96.3%, respectively, with an accuracy of 94.3% (p < .05). CONCLUSION The mid-trimester ultrasound scan had good accuracy in the detection of congenital malformations, although the overall sensitivity does not support it as the only screening test for anomalies throughout pregnancy.

Abstract
There is mounting evidence to implicate the intrauterine environment as the initial pathogenic stage for neuropsychiatric disease. Recent developments in magnetic resonance imaging technology are making a multimodal analysis of the fetal central nervous system a reality, allowing analysis of structural and functional parameters. Exposures to a range of pertinent risk factors whether preconception or in utero can now be indexed using imaging techniques within the fetus' physiological environment. This approach may determine the first "hit" required for diseases that do not become clinically manifest until adulthood, and which only have subtle clinical markers during childhood and adolescence. A robust characterization of a "multi-hit" hypothesis may necessitate a longitudinal birth cohort; within this investigative paradigm, the full range of genetic and environmental risk factors can be assessed for their impact on the early developing brain. This will lay the foundation for the identification of novel biomarkers and the ability to devise methods for early risk stratification and disease prevention. However, these early markers must be followed over time: first, to account for neural plasticity, and second, to assess the effects of postnatal exposures that continue to drive the individual toward disease. We explore these issues using the schizophrenia spectrum disorders as an illustrative paradigm. However, given the potential richness of fetal magnetic resonance imaging, and the likely overlap of biomarkers, these concepts may extend to a range of neuropsychiatric conditions.

Abstract
BACKGROUND Third-trimester scans are increasingly used to try to prevent adverse outcomes associated with abnormalities of fetal growth. Unexpected fetal malformations detected at third-trimester growth scans are rarely reported. OBJECTIVE To determine the incidence and type of fetal malformations detected in women attending a routine third-trimester growth scan. STUDY DESIGN This was a population-based study of all women with singleton pregnancy attending antenatal care over a 2-year period in Oxfordshire, UK. Women who had a viable singleton pregnancy at dating scan were included. Women had standard obstetrical care including the offer of a routine dating scan and combined screening for trisomies; a routine anomaly scan at 18 to 22 weeks; and a routine third-trimester growth scan at 36 weeks. The third-trimester scan comprises assessment of fetal presentation, amniotic fluid, biometry, umbilical and middle cerebral artery Dopplers, but no formal anatomic assessment is undertaken. Scans are performed by certified sonographers or clinical fellows (n=54), and any suspected abnormalities are evaluated by a team of fetal medicine specialists. We assessed the frequency and type of incidental congenital malformations identified for the first time at this third-trimester scan. All babies were followed-up after birth for a minimum of 6 months. RESULTS There were 15,244 women attending routine antenatal care. Anomalies were detected in 474 (3.1%) fetuses as follows: 103 (21.7%) were detected before the anomaly scan, 174 (36.7%) at the anomaly scan, 11 (2.3%) after the anomaly scan and before the third-trimester scan, 43 (9.1%) at the third-trimester scan and 143 (30.2%) after birth. The 43 abnormalities were found in a total of 13,023 women who had a 36 weeks scan, suggesting that in 1 out of 303 (95% confidence interval, 233-432) women attending such a scan, a new malformation was detected. Anomalies detected at the routine third-trimester scan were of the urinary tract (n=30), central nervous system (5), simple ovarian cysts (4), chromosomal (1), splenic cyst (1), skeletal dysplasia (1), and cutaneous lymphangioma (1). Most urinary tract anomalies were renal pelvic dilatation, which showed spontaneous resolution in 57% of the cases. CONCLUSION When undertaking a program of routine third-trimester growth scans in women who have had previous screening scans, an unexpected congenital malformation is detected in approximately 1 in 300 women.

Abstract
Neural stem cell (NSC) transplantation has provided the basis for the development of potentially powerful new therapeutic cell-based strategies for a broad spectrum of clinical diseases, including stroke, psychiatric illnesses such as fetal alcohol spectrum disorders, and cancer. Here, we discuss pertinent preclinical investigations involving NSCs, including how NSCs can ameliorate these diseases, the current barriers hindering NSC-based treatments, and future directions for NSC research. There are still many translational requirements to overcome before clinical therapeutic applications, such as establishing optimal dosing, route of delivery, and timing regimens and understanding the exact mechanism by which transplanted NSCs lead to enhanced recovery. Such critical lab-to-clinic investigations will be necessary in order to refine NSC-based therapies for debilitating human disorders.

Abstract
BACKGROUND Duodenal obstruction (DO) is associated with congenital cardiac anomalies that may complicate the delivery of anesthesia during surgical repair. As most infants undergo fetal ultrasounds that identify cardiac anomalies, our aim was to determine the utility of obtaining preoperative neonatal echocardiograms in all DO patients. METHODS We conducted a retrospective cohort study of all DO patients treated at two tertiary care children's hospitals between January 2005 and February 2016. Prenatal ultrasounds were compared to neonatal echocardiograms to determine concordance. Binomial exact analyses were used to estimate the negative predictive value (NPV) of prenatal imaging. RESULTS We identified 65 infants with DO. The majority of patients (93.8%) had prenatal ultrasounds, including twenty patients that underwent fetal echocardiogram. Fourteen (21.5%) were diagnosed with cardiac lesions in utero, and neonatal echocardiograms confirmed 12 lesions, without identifying any new lesions. No changes to anesthetic management were made because of cardiac lesions. The NPV of prenatal imaging was 100% (95% Confidence Interval: 91.0-100.0). CONCLUSIONS Neonatal echocardiogram is unlikely to identify new cardiac lesions in DO patients with negative fetal imaging and delays in surgical care are unwarranted. LEVELS OF EVIDENCE Study of Diagnostic Test-Level II.

Abstract
We are entering a new era of understanding human development with the ability to perform studies at the earliest time points possible. There is a substantial body of evidence to support the concept that early motor behaviour originates from supraspinal motor centres, reflects neurological integrity, and that altered patterns of behaviour precede clinical manifestation of disease. Cine Magnetic Resonance Imaging (cineMRI) has established its value as a novel method to visualise motor behaviour in the human fetus, building on the wealth of knowledge gleaned from ultrasound based studies. This paper presents a state of the art review incorporating findings from human and preclinical models, the insights from which, we propose, can proceed a reconceptualisation of fetal motor behaviour using advanced imaging techniques. Foremost is the need to better understand the role of the intrauterine environment, and its inherent unique set of stimuli that activate sensorimotor pathways and shape early brain development. Finally, an improved model of early motor development, combined with multimodal imaging, will provide a novel source of in utero biomarkers predictive of neurodevelopmental disorders.

Abstract
Brain insults with progressive neurodegeneration are inherent in pathological symptoms that represent many psychiatric illnesses. Neural network disruptions characterized by impaired neurogenesis have been recognized to precede, accompany, and possibly even exacerbate the evolution and progression of symptoms of psychiatric disorders. Here, we focus on the neurodegeneration and the resulting psychiatric symptoms observed in fetal alcohol spectrum disorder and epilepsy, in an effort to show that these two diseases are candidate targets for stem cell therapy. In particular, we provide preclinical evidence in the transplantation of neural stem cells (NSCs) in both conditions, highlighting the potential of this cell-based treatment for correcting the psychiatric symptoms that plague these two disorders. Additionally, we discuss the challenges of NSC transplantation and offer insights into the mechanisms that may mediate the therapeutic benefits and can be exploited to overcome the hurdles of translating this therapy from the laboratory to the clinic. Our ultimate goal is to advance stem cell therapy for the treatment of psychiatric disorders.

Abstract
Synopsis The establishment of a multidisciplinary consultation system is necessary for the diagnosis of complicated fetal anomalies. Purpose We aimed to investigate the incidences of different types of fetal anomalies and the influence of multidisciplinary consultation on fetal prognosis. Patients and methods Multidisciplinary specialists include obstetricians, pediatricians, pediatric surgeons, and experts of ultrasound department and genetic counseling. Consultation was done if the fetal ultrasound examinations showed abnormality. Follow-up, assistance, and guidance for the fetus were achieved by phone calls. Results Ultrasound screening showed that the incidences of central nervous system anomaly and genitourinary anomaly were 25.80% (275/1,066) and 22.05% (235/1,066), respectively. The detection rates of fetal anomalies were 5.07% (54/1,066), 36.12% (385/1,066), and 58.82% (627/1,066) in pregnant women with gestational age of <20, 20–28, and >28 weeks, respectively. In addition, the fetal cerebral ventriculomegaly accounted for 40.73% of central nervous system malformation, while 71.43% cases with fetal cerebral ventriculomegaly were alleviated during the follow-up period. The proportion of hydronephrosis in genitourinary anomalies was 50.64%, and the remission rate of hydronephrosis was 67.23% during the follow-up period. Conclusion The establishment of a multidisciplinary consultation system is necessary for the diagnosis of complicated fetal anomalies. The central nervous system anomaly and genitourinary anomaly are the most common fetal anomalies. In addition, the remission rates of cerebral ventriculomegaly and fetal hydronephrosis are high during the follow-up period.

Abstract
OBJECTIVES To determine the sensitivity and specificity of first-trimester ultrasound for the detection of fetal abnormalities and to establish which factors might impact on screening performance. METHODS A systematic review and meta-analysis of all relevant publications was performed to assess the diagnostic accuracy of two-dimensional transabdominal and transvaginal ultrasound in the detection of congenital fetal anomalies prior to 14 weeks' gestation. The reference standard was detection of abnormalities at birth or postmortem. Factors that may impact on detection rates were evaluated, including population characteristics, gestational age, healthcare setting, ultrasound modality, use of an anatomical checklist for detection of first-trimester anomalies and type of malformation included in the study. In an effort to reduce the impact of study heterogeneity on the results of the meta-analysis, data from the studies were analyzed within subgroups of major anomalies vs all types of anomaly and low-risk/unselected populations vs high-risk populations. RESULTS An electronic search (until 29 July 2015) identified 2225 relevant citations, from which a total of 30 studies, published between 1991 and 2014, were selected for inclusion. The pooled estimate for the detection of major abnormalities in low-risk or unselected populations (19 studies, 115 731 fetuses) was 46.10% (95% CI, 36.88-55.46%). The detection rate for all abnormalities in low-risk or unselected populations (14 studies, 97 976 fetuses) was 32.35% (95% CI, 22.45-43.12%), whereas in high-risk populations (six studies, 2841 fetuses) it was 61.18% (95% CI, 37.71-82.19%). Of the factors examined for their impact on detection rate, there was a statistically significant relationship (P < 0.0001) between the use of a standardized anatomical protocol during first-trimester anomaly screening and its sensitivity for the detection of fetal anomalies in all subgroups. CONCLUSIONS Detection rates of first-trimester fetal anomalies ranged from 32% in low-risk groups to more than 60% in high-risk groups, demonstrating that first-trimester ultrasound has the potential to identify a large proportion of fetuses affected with structural anomalies. The use of a standardized anatomical protocol improves the sensitivity of first-trimester ultrasound screening for all anomalies and major anomalies in populations of varying risk. The development and introduction of international protocols with standard anatomical views should be undertaken in order to optimize first-trimester anomaly detection. Copyright © 2016 ISUOG.

Abstract
Fetal bladder outlet obstruction (BOO), most commonly caused by posterior urethral valves (PUV), remains a challenging and multi-faceted condition. Evolving techniques, and refinement in ultrasound, optics and instrumentation, have increased our rate of prenatal diagnosis, and enabled valve ablation not only in smaller newborns, but also in fetuses. Long-term outcome studies have raised our awareness of the silent damage caused by bladder dysfunction and polyuria and encouraged their proactive management. In spite of our best efforts, the proportion of boys with PUV who progress to chronic and end-stage renal disease (ESRD) has not changed in the last 25 years. Evidence suggests a reduction in perinatal mortality following prenatal intervention, probably resulting from amelioration of oligohydramnios at the crucial time of lung development between 16 and 28 weeks' gestation, but no improvement in postnatal renal outcome. There are no bladder functional outcome studies in patients who have undergone prenatal intervention and hence the long-term effect of in utero defunctionalisation of the bladder is not known. This aim of this review is to revisit the embryopathology of fetal BOO, in particular the renal and bladder structural and functional changes that occur with in utero obstruction. The effect of earlier prenatal diagnosis, and therapy, on postnatal outcome is also explored and compared with outcomes published for traditional postnatal treatment.

Abstract
Spina bifida aperta are complex congenital malformations resulting from failure of fusion in the spinal neural tube during embryogenesis. Despite surgical repair of the defect, most patients who survive with spina bifida aperta have a multiple system handicap due to neuron deficiency of the defective spinal cord. Tissue engineering has emerged as a novel treatment for replacement of lost tissue. This study evaluated the prenatal surgical approach of transplanting a chitosan-gelatin scaffold seeded with bone marrow mesenchymal stem cells (BMSCs) in the healing the defective spinal cord of rat fetuses with retinoic acid induced spina bifida aperta. Scaffold characterisation revealed the porous structure, organic and amorphous content. This biomaterial promoted the adhesion, spreading and in vitro viability of the BMSCs. After transplantation of the scaffold combined with BMSCs, the defective region of spinal cord in rat fetuses with spina bifida aperta at E20 decreased obviously under stereomicroscopy, and the skin defect almost closed in many fetuses. The transplanted BMSCs in chitosan-gelatin scaffold survived, grew and expressed markers of neural stem cells and neurons in the defective spinal cord. In addition, the biomaterial presented high biocompatibility and slow biodegradation in vivo. In conclusion, prenatal transplantation of the scaffold combined with BMSCs could treat spinal cord defect in fetuses with spina bifida aperta by the regeneration of neurons and repairmen of defective region.

Abstract
OBJECTIVE During an early second-trimester transvaginal ultrasound anomaly scan, pressure is applied to the uterus, and the fetus is often rotated manually to allow scanning of its various organs. This study was designed to determine if performing a transvaginal ultrasound anomaly scan during the early second trimester of pregnancy is associated with adverse perinatal outcome or cord entanglement. METHODS During the 4.5year study period we prospectively collected cases of routine ultrasound scans at 14-17weeks gestation performed as anomaly screening, together with perinatal outcome. The study population consisted of 164 women who underwent a transvaginal approach, and the control population consisted of 224 women in which a transabdominal approach was used. Data on perinatal parameters was collected from delivery charts from the four local hospitals. RESULTS There were more operative deliveries (vaginal or Cesarean) in the transvaginal scan group (32% vs. 23%, p=0.05). However, on multiple logistic regression analysis vaginal scans were not associated with increased operative delivery rates with an adjusted odds ratio of 1.47 and a 95% confidence interval of 0.85-2.54. There were no other clinically significant differences in perinatal outcomes, or in cord entanglement. CONCLUSIONS Transvaginal ultrasound anomaly scan conducted in the early second trimester of pregnancy is a safe procedure for the fetus.

Abstract
Fetal alcohol spectrum disorder (FASD) is caused by intrauterine exposure to alcohol and can cause a full range of abnormalities to brain development, as well as long-term sequelae of cognitive, sensory and motor impairments. The incidence is estimated to be as high as 2% to 5% in children born within the US, however the prevalence is even higher in low socioeconomic populations. Despite the various mechanisms thought to explain the etiology of FASD, molecular targets of ethanol toxicity during development are not completely understood. More recent findings explore the role of GABA-A and GABA-B mechanisms, as well as cell death, cell signaling and gene expression malfunctions. Stem cell based therapies have grown exponentially over the last decade, which have lead to novel clinical interventions across many disciplines. Thus, early detailed understanding of the therapeutic potential of stem cell research has provided promising applications across a wide range of illnesses. Consequently, these potential benefits may ultimately lead to a reduced incidence and severity of this highly preventable and prevalent birth defect. It is recognized that stem cell derivations provide unique difficulties and limitations of therapeutic applications. This review will outline the current knowledge, along with the benefits and challenges of stem cell therapy for FASD.

Abstract
BACKGROUND Congenital malformations occur in 3-4% of live births. Their prenatal detection is performed by ultrasound screening. Any announcement about a suspected malformation is a source of stress for the parents, and misdiagnosis during ultrasound screening can lead to expensive and sometimes iatrogenic medical interventions. In this study, we aim to determine the false-positive rate, first overall and then by anatomical system, of ultrasound screening for congenital malformations in the second and third trimesters of pregnancy. METHODS Our sample includes all children born between 1 January, 2006, and 31 December, 2009, in the French region of Auvergne, whose mother had a prenatal ultrasound diagnosis of a congenital malformation during the second or third trimester of pregnancy confirmed by a follow-up ultrasound examination by an expert consultant ultrasonographer. The study included 526 fetuses, divided in 3 groups: false positives, diagnostic misclassifications, and true positives. The rates of false positives and diagnostic misclassifications were calculated for the sample as a whole and then by anatomical system. RESULTS Overall, the false-positive rate was 8.8% and the rate of diagnostic misclassification 9.2%. The highest false-positive rates were found for renal and gastrointestinal tract malformations, and the highest diagnostic misclassification rates for cerebral and cardiac malformations. The diagnostic misclassification rate was significantly higher than the false-positive rate for cardiac malformations. CONCLUSION The false-positive rate during prenatal ultrasound is not insignificant; these misdiagnoses cause psychological stress for the parents and overmedicalisation of the pregnancy and the child.

Abstract
Whereas structural fetal abnormalities are relatively frequent occurrences, many of these do not impact measurably on future life and/or are amenable to postnatal therapy. A small minority are considered to be potentially lethal or life-limiting. Examples include specific skeletal dysplasias, urinary tract abnormalities - typically those which lead to anhydramnios and pulmonary hypoplasia, some disorders of the central nervous system and trisomies 13 and 18. Without seeking to compile an exhaustive list of such conditions, we discuss the principles and new considerations in relation to antenatal diagnosis and perinatal management of such disorders.

Abstract
Neural tube defects (NTDs) are complex congenital malformations resulting from incomplete neurulation in embryo. Despite surgical repair of the defect, most of the patients who survive with NTDs have a multiple system handicap due to neuron deficiency of the defective spinal cord. In this study, we successfully devised a prenatal surgical approach and transplanted mesenchymal stem cells (MSCs) to foetal rat spinal column to treat retinoic acid induced NTDs in rat. Transplanted MSCs survived, grew and expressed markers of neurons, glia and myoblasts in the defective spinal cord. MSCs expressed and perhaps induced the surrounding spinal tissue to express neurotrophic factors. In addition, MSC reduced spinal tissue apoptosis in NTD. Our results suggested that prenatal MSC transplantation could treat spinal neuron deficiency in NTDs by the regeneration of neurons and reduced spinal neuron death in the defective spinal cord.

Abstract
OBJECTIVE To review changes in and impact of prenatal screening and diagnosis. DESIGN Population-based congenital anomaly register study. SETTING Oxfordshire. POPULATION Congenital anomalies confirmed and those suspected prenatally, delivered 1991-2008. METHODS Analysis of proportions of congenital anomalies confirmed and those suspected prenatally. MAIN OUTCOME MEASURES Birth prevalence, prenatal detection rates, pregnancy outcomes. RESULTS A total of 2651 (2.3%) infants/fetuses had a congenital anomaly diagnosed. There were 3839 suspected or confirmed cases, 2847 due to a prenatal suspicion, of which 1659 had an anomaly confirmed at delivery, and 1188 false-positive diagnoses, 91% due to reporting ultrasound normal variants. The percentage of prenatal notifications rose from 48% in 1991-93 to 83-88% from 1996 to 2003 and dropped to 61% in 2006-08, partly reflecting changes in the reporting of normal variants. Reporting these increased the prenatal diagnosis rate from 53 to 63% with an increase in false-positive rate from 0.09 to 1.04%. A total of 722 (44% of prenatally detected affected fetuses) resulted in termination; 48% of these had chromosome anomalies, 34% had isolated structural anomalies, 7% had multiple anomalies, 10% had familial disorders; 42% had lethal anomalies and 58% would probably have survived the neonatal period giving an estimated 20% reduction in birth prevalence of congenital anomalies compatible with survival because of terminations. CONCLUSION There has been an improvement in prenatal detection of congenital anomalies over the two decades studied. The recognition that reporting normal variants, although increasing prenatal detection rates, leads to an increase in false-positive diagnoses has had an impact on practice that has redressed the balance between these two effects.

Abstract
BACKGROUND Falling consent rates for postmortems, regardless of age of death, have been widely reported in recent years. The aim of this study was to explore parental attitudes to, and decision-making about, a perinatal postmortem after termination for fetal abnormality, late miscarriage, or stillbirth. METHODS A prospective self-completion questionnaire was given to 35 women and their partners. The participants had experienced second or third trimester pregnancy loss in a single fetal medicine and delivery unit in the United Kingdom and were making decisions about having a postmortem. They were asked to complete a questionnaire about their attitudes to, and expectations of, a perinatal postmortem. RESULTS Thirty-one questionnaires were received from parents of 17 babies (49% of those asked; 16 from mothers, 15 from fathers). Parents of nine babies (53%) said they would agree to a full postmortem, of three babies to a limited postmortem, and of four babies to an external examination only; one couple were undecided. The most important issues for the parents in this study that related to their decisions about a postmortem centered on the need for information, both for future planning and about what had happened. Moderately important issues related to altruism, which is, improving medical knowledge and helping other parents experiencing similar bereavement. Among the lowest scoring issues were potential barriers, such as concerns about cultural or religious acceptability of a postmortem, funeral delays, and what would happen to the baby's body. CONCLUSIONS Bereaved parents who participated in this study, where postmortem consent rates were relatively high, thought that their need for knowledge eclipsed assumed barriers when deciding whether or not to have a postmortem for their baby.

Abstract
This article reports on the evolving field of stem cell therapy and its impact on the management of cardiac pathology, in particular congenital heart disease. To date, stem cell therapy has focused on cardiomyoplasty for heart muscle disease, stem cell therapies are already in clinical use for these disorders. Research is now also supporting the potential role of stem cell therapy for congenital heart disease. In the future it may be possible to use stem cells to create cellular grafts and structures that may be surgically implanted into the disordered heart using bioengineering technology. Different types of stem cells have been evaluated and the identification of specific cardiac stem cells offers great potential. Preliminary animal studies investigating fetal cardiac therapies are also underway. These new directions for stem cell research provide exciting potential for the future management of congenital heart disease.

Abstract
Posterior urethral valves occur in 1 : 5000 live births. Despite the high prevalence, the few children that survive do poorly, with over 50% progressing to ESRD in 10 years. The gold standard for post-natal diagnosis is voiding cystourethrography, while pre-natal diagnosis is dependent on routine screening ultrasonography. Despite the ability to identify features of bladder outlet obstruction early in fetal development, there is no consensus on how to incorporate early detection into current screening protocols. There has yet to be a marker that allows prediction of obstruction in the absence of or prior to radiographic evidence of obstruction. With our current screening strategy, the majority of interventions are performed well after irreversible damage has occurred. Improved mortality and long term morbidity from posterior urethral valves and congenital bladder outlet obstruction will likely remain unchanged until it is possible to intervene prior to the onset of irreversible renal damage. New biologic markers and improved instrumentation will allow for more effective diagnosis and intervention at earlier stages of fetal development.

Abstract
PURPOSE The purpose of this study is to examine the impact of prenatal ultrasonography (US) on the birth of babies with diseases listed on the Korean pediatric surgery index diseases (IDs). METHODS Depending the ease of diagnosis using prenatal US, [diagnostic facility if prenatal US] IDs were divided into easily diagnosed (ED), not easily diagnosed (NED) and detected with difficulty (DD) groups. Five-year data were obtained for the total live birth number (TBN) from the Korean Statistical Information Service, and the actual birth number of IDs (ABNID) from the Korean Health Insurance Review and Assessment Service. The certified incidences of IDs (I) were obtained from a prestigious textbook of pediatric surgery. The estimated abortion rate (AR) of fetus in each group was obtained using the following formula: AR (%) = [1 - (ABNID)/(TBN × I)] × 100. RESULTS The AR with all IDs was 38 to 77%. The AR was 78 to 93% for ED group, 38 to 66% for NED group and 0% for DD group. CONCLUSION In spite of high survival rates after treatment, the AR of each group depends on the ease of diagnosis using prenatal US in Korea. A recommendatory policy for the fetus with IDs should be urgently established after general consensus within the related medical societies.

Abstract
The term congenital ‘bladder outlet obstruction (BOO)’ describes the collection of conditions in which the normal, urethral egress of urine from the fetal bladder is impaired. The term is interchangeable with fetal ‘lower urinary tract obstruction’, as used by other authors. After considering normal urinary tract embryology, we describe the epidemiology of congenital BOO and the primary anatomical disorders associated with it. We then proceed to describe its fetal and postnatal clinical manifestations and then consider therapies and interventions which have been used to manage the condition. We not only focus on urethral and bladder disease with constitutes BOO itself, but also describe associated kidney disorders which, via chronic renal excretory failure, are important causes of morbidity. Rather than provide an exhaustive review, we emphasise studies published in the last decade, and therefore readers are referred to other reviews citing numerous earlier references.
