Renal - national antenatal renal dilation guideline

A New Zealand guideline has been developed to better manage antenatally detected fetal renal dilatation. The guideline aims to better differentiate between those at low risk and those at high risk of surgically significant dilatation, better directing those at high risk to appropriate specialist care and reducing the number of scans for those at low risk.
