Antenatal diagnosis of renal tract anomalies: Has it increased the sum of human happiness?

Abstract

When used as a screening procedure, ultrasound examination of the fetal urinary tract seldom leads to beneficial interventions. There is also a cost in terms of parental anxiety and unnecessary investigation and treatment. A formal screening programme would therefore be unjustified. However, screening of women for obstetric purposes will continue to reveal fetal abnormalities, and a strategy for dealing with these is needed. Antenatal treatments remain experimental; for most of the common conditions postnatal treatment has no urgency; and, in cases of minor abnormality detected by ultrasound, the best course may be to do nothing.
