OC16.04: *Antenatal characteristics of postnatal diagnosed lower urinary tract obstructions.

This article discusses a study conducted in the Netherlands between 2013 and 2023, which aimed to assess the prevalence, accuracy of antenatal diagnosis, and prognosis of Lower Urinary Tract Obstruction (LUTO) in fetuses with hydronephrosis and/or obstructive uropathy. The study found that LUTO was postnatally diagnosed in 9% of the 437 fetuses included in the study, with a higher prevalence in male cases. Neonatal mortality occurred in 13% of the LUTO cases. The study also revealed that a significant percentage of postnatally diagnosed LUTO cases did not present the classical antenatal indicators of LUTO, highlighting the importance of thorough postnatal follow-up.
