"The urinary tract dilation (UTD) classification system is a proposed unified classification of urinary tract dilatation for prenatal and postnatal care. This classification was developed by the collaboration of clinicians from eight societies (American College of Radiology (ACR), American Institute of Ultrasound in Medicine (AIUM), American Society of Paediatric Nephrology (ASPN), Society for Fetal Urology (SFU), Society for Maternal-Fetal Medicine (SMFM), Society for Paediatric Urology (SPU), Society for Paediatric Radiology (SPR), and the Society of Radiologists in Ultrasound (SRU)) 1.In 2021, Nguyen et al. updated and clarified the classification system, drawing on the experience gathered from the use of the 2014 classification 4. The following is based on the update:"
