New guideline clarifies ultrasound use for postnatal ultrasound referrals for follow-up of antenatally detected renal pelvic dilatation

The British Medical Ultrasound Society (BMUS) has released a guideline to assist healthcare professionals in managing paediatric postnatal ultrasound referrals for follow-up of antenatally detected renal pelvic dilatation, focussing on appropriate ultrasound use. Antenatally detected renal pelvic dilatation has an estimated incidence of 0.5 – 1% of all pregnancies, sometimes being transient and resolved by birth; however, some cases have significant associated pathology. Postnatal follow-up is performed to confirm the presence of renal pelvic dilatation and to further characterise this, in addition to identifying any potential other urinary tract abnormalities. Currently, no national guidelines are available to advise for appropriate and consistent follow-up. These BMUS guidelines have been produced collaboratively by the BMUS Obstetric and Paediatric Special Interest Groups.

Ultrasound is highlighted as a crucial diagnostic tool, but its use should be selective. The guideline recommends antenatal ultrasound findings requiring postnatal follow-up including suggested scan timing, urgency, and patient preparation. Additionally, information on how to consistently measure detected renal dilatation to ensure consistency is also included.

By providing clear criteria for when ultrasound is necessary, the guideline aims to ensure timely and appropriate care, minimising unnecessary procedures while facilitating early detection of serious conditions.
