Summary
This prospective study aimed to assess the value of postnatal ultrasound screening for congenital anomalies of the kidney and urinary tract (CAKUT) during the early postnatal period. The research included 4,877 infants who underwent ultrasound screening at 1, 3, and 6 months of age.
The primary screening identified 5.5% of cases with CAKUT, and a specific diagnosis was established in 47 cases during the 6-month screening and follow-up. Preterm birth, oligohydramnios, antenatal ultrasound anomalies, and gestational hypothyroidism were identified as independent risk factors for early CAKUT detection by postnatal ultrasound screening. A predictive model based on these factors demonstrated good clinical utility, suggesting the importance of postnatal ultrasound screening in infants with CAKUT risk factors.
