Abstract
Fetal upper tract urinary system dilation is one of the most common findings on prenatal ultrasonography. Rarely, this may represent fetal lower urinary tract obstruction (LUTO), of which posterior urethral valves are the predominant etiology. LUTO is the most dire fetal urologic diagnosis, as it affects not only the baby's management after birth but sometimes the course of the pregnancy itself. A variety of treatment options are available prenatally; these include observation, vesicoamniotic shunt placement, amnioinfusion, and attempts at direct treatment of the valves themselves. All fetal interventions carry substantial risks; caution should attend every discussion of treatment.

Abstract
Bilateral renal agenesis is associated with severe oligohydramnios and was considered incompatible with postnatal life due to severe pulmonary hypoplasia. The use of renal replacement therapy was limited by significant morbidity and mortality associated with dialysis in very young infants with major pulmonary pathology. In the United States, there is a tremendous controversy about whether or not the use of prenatal amniotic fluid infusions provides a benefit to fetuses with bilateral renal agenesis. One of the critical issues identified is that there are, as yet, no children reported who had achieved long-term survival. Previous reports all indicated these children died shortly after birth or after unsuccessful peritoneal dialysis. We present two infants with a prenatal diagnosis of bilateral renal agenesis whose mothers elected to undergo prenatal amnioinfusions. One was born at 28 weeks with a birthweight of 1230 g and the other born at 34 weeks with a birthweight of 1940 g. We present the details of both cases, with initial management on chronic peritoneal dialysis, which started shortly after birth, as a bridge to living related kidney transplants.

Ethical Considerations Concerning Amnioinfusions for Treating Fetal Bilateral Renal Agenesis. Obstet Gynecol 2018; 131:130-134. [PMID: 29215523 DOI: 10.1097/aog.0000000000002416] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
Congenital bilateral renal agenesis has been considered a uniformly fatal condition. However, the report of using serial amnioinfusions followed by the live birth in 2012 and ongoing survival of a child with bilateral renal agenesis has generated hope, but also considerable controversy over an array of complex clinical and ethical concerns. To assess the ethical concerns associated with using serial amnioinfusions for bilateral renal agenesis, we assembled a multidisciplinary group to map the ethical issues relevant to this novel intervention. The key ethical issues identified were related to 1) potential risks and benefits, 2) clinical care compared with innovation compared with research, 3) counseling of expectant parents, 4) consent, 5) outcome measures, 6) access and justice, 7) conflicts of interest, 8) effects on clinicians, 9) effects on institutions, and 10) long-term societal implications. These ethical issues should be addressed in conjunction with systematic efforts to examine whether this intervention is safe and effective. Future work should capture the experiences of expectant parents, women who undergo serial amnioinfusions, those born with bilateral renal agenesis and their families as well as clinicians confronted with making difficult choices related to it.

Abstract
BACKGROUND Not much data are available on the natural history of bilateral renal agenesis, as the medical community does not typically offer aggressive obstetric or neonatal care asbilateral renal agenesis has been accepted as a lethal condition. AIM To provide an evidence-based, ethically justified approach to counseling pregnant women about the obstetric management of bilateral renal agenesis. STUDY DESIGN A systematic literature search was performed using multiple databases. We deploy an ethical analysis of the results of the literature search on the basis of the professional responsibility model of obstetric ethics. RESULTS Eighteen articles met the inclusion criteria for review. With the exception of a single case study using serial amnioinfusion, there has been no other case of survival following dialysis and transplantation documented. Liveborn babies die during the neonatal period. Counseling pregnant women about management of pregnancies complicated by bilateral renal agenesis should be guided by beneficence-based judgment informed by evidence about outcomes. CONCLUSIONS Based on the ethical analysis of the results from this review, without experimental obstetric intervention, neonatal mortality rates will continue to be 100%. Serial amnioinfusion therefore should not be offered as treatment, but only as approved innovation or research.

Abstract
INTRODUCTION The Genetic Branch of the Chilean Society of Paediatrics, given the draft Law governing the decriminalisation of abortion on three grounds, focusing on the second ground, which considers the "embryo or foetus suffering from a congenital structural anomaly or a genetic disorder incompatible with life outside the womb", met to discuss the scientific evidence according to which congenital anomalies (CA) may be included in this draft law. METHODOLOGY Experts in clinical genetics focused on 10 CA, reviewed the literature evidence, and met to discuss it. RESULTS It was agreed not to use the term "incompatible with life outside the womb", as there are exceptions and longer survivals, and change to "congenital anomaly of poor prognosis (CAPP)". Ten CA were evaluated: serious defects of neural tube closure: anencephaly, iniencephaly and craniorachischisis, pulmonary hypoplasia, acardiac foetus, ectopia cordis, non-mosaic triploidy, "limb body wall" complex, "body stalk" anomaly, trisomy 13, trisomy 18, and bilateral renal agenesis. Findings on the prevalence, natural history, prenatal diagnostic methods, survival, and reported cases of prolonged survival were analysed. Post-natal survival, existence of treatments, and outcomes, as well as natural history without intervention, were taken into account in classifying a CA as a CAPP. CONCLUSION A CAPP would be: anencephaly, severe pulmonary hypoplasia, acardiac foetus, cervical ectopia cordis, non-mosaic triploidy, limb body wall complex, body stalk anomaly, non-mosaic trisomy 13, non-mosaic trisomy 18, and bilateral renal agenesis. For their diagnosis, it is required that all pregnant women have access to assessments by foetal anatomy ultrasound and occasionally MRI, and cytogenetic and molecular testing.

Am J Prev Med 2016; 50:663-671. [PMID: 26895742 DOI: 10.1016/j.amepre.2015.12.013] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2015] [Revised: 11/22/2015] [Accepted: 12/17/2015] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Congenital anomalies (CAs) contribute significantly to under-5-years child mortality (U5M) throughout the world. This study analyzed trends in the CA-specific U5M rate in urban and rural China. METHODS This population-based epidemiologic study used data obtained by China's National U5M Surveillance System from 1996 to 2013. Data from national surveillance sites were used to examine CA-specific U5M rates by year, urban and rural habitation, and sex. Mixed effect negative binomial regression models were used to assess the trends in CA-specific U5M rates and differences in those trends between urban and rural areas. RESULTS The CA-specific U5M rate decreased from 407.7 per 100,000 live births in 1996 to 217.4 per 100,000 live births in 2013, with average annual decline rates of 6.4% (95% CI=5.6%, 7.1%) and 3.8% (95% CI=3.3%, 4.3%) in urban and rural areas, respectively. The CA-specific U5M rate was the same in both rural and urban areas in 1996, but the U5M rate of the rural areas was 1.621-fold of that of urban areas in 2013. In urban and rural China, cardiovascular anomalies were the most frequent CAs, accounting for 50.3% and 58.2% of U5M due to CA, respectively. CONCLUSIONS CAs have become one of the leading causes of U5M in both urban and rural China and the difference between the CA-specific U5M rates in two areas is gradually increasing. Reduction of child mortality due to CAs and elimination of the geographic disparity in child mortality rates should be major public health concerns in China.
