ObjectivesTo estimate the prevalence of kidney anomalies at second trimester ultrasound screening, and furthermore, to investigate pregnancy outcomes and the pattern of additional malformations. MethodsWe previously identified all women attending second-trimester ultrasound scans in Denmark between 1 January 2007 and 31 December 2012. Using the Astraia databases and the Danish National Patient Registry, we identified all fetuses with kidney anomalies diagnosed prenatally in these women. In addition to the prevalence of fetuses with kidney anomalies, we estimated the live birth prevalence ratio of non-urinary malformations, comparing the prevalences in infants with and without prenatally diagnosed kidney anomalies. ResultsThe prevalence of fetuses with kidney anomalies at second trimester scans was 11.4 per 10000 fetuses. Among the 412 fetuses identified, 127 pregnancies were terminated. For live born children the prevalence of additional non-urinary malformations was four times higher (95% CI: 3-5) compared with the prevalence among children without prenatal kidney anomalies. Digestive system anomalies were particularly prevalent. ConclusionThese population-based data provide additional insight into the course of pregnancy and birth outcomes following prenatal diagnoses of kidney anomalies. (c) 2016 John Wiley & Sons, Ltd.
