Selective abortion was shown to be increasingly common in England and Wales over a 9-year period, occurring most frequently as twin to singleton reductions in the 1st trimester. We analysed the trends in selective abortion (SA) in multiple pregnancies in England and Wales between 2009 and 2018. This is a cross-sectional study looking at 1143 women with multiple pregnancies in England and Wales undergoing SA. There were a total of 1143 cases of SA between 2009 and 2018 in England and Wales, representing 0.07% of total abortions. There has been a steady increase in cases, from 90 in 2009 to 131 in 2018, with 82.3% justified under ground E of The Abortion Act 1967. The majority of SAs were carried out at 13–19 weeks gestation, and intracardiac injection of potassium chloride was the most prevalent method (75%). Twin to singleton reductions accounted for 59%, the most common form of SAs. Over half of all cases (59%) were performed in women aged 30–39 years, and 84% of all women were of White ethnicity. SA has been an option available for couples diagnosed with multiple pregnancy, especially when there are discordant anomalies. Although SA may decrease multiple pregnancy-related complications, preventative methods must be championed.

The detection of developmental abnormalities in the foetus is considered an essential component of antenatal screening. Among the most frequently identified sonographically, and possibly one of the easiest recognised, are those affecting the urinary tract, with an incidence of 1–4 in 1000 pregnancies. As such, foetal urological abnormalities represent up to 30% of all prenatally diagnosed congenital anomalies. We analysed information recorded on the Health and Social Act 4 (HSA4) forms submitted to the Department of Health and Social Care (DHSC) for 2015 to 2019. There were 915 cases of termination of pregnancy for foetal urological anomaly between 2015 and 2019 in England and Wales, representing 0.09% of total abortions. There has been a steady increase in cases, from 186 in 2015 to 222 in 2018, followed by a more recent decline in 2019 to 172. All 915 cases were justified under Ground E of The Abortion Act 1967. Most terminations of pregnancy for foetal urological anomaly were carried out at 20 weeks gestation. Isolated urinary tract single diagnoses were the commonest, with megacystis being the most prevalent, followed by bilateral renal agenesis and bilateral cystic kidneys. Nearly a third of cases (32.2%) were performed in women aged 30–34 years, and almost 4/5 of women (78.7%) were of White ethnicity. Foetal urological abnormality is a complex issue affecting a significant minority of pregnant women. When severe abnormalities are detected by prenatal diagnosis, most women choose to terminate the pregnancy.
