Introduction: The American Consensus established risk groups for urinary tract dilation (UTD), however it has not been validated. Purpose: To validate the usefulness of the upper UTD risk groups according to a long-term outcome of patients stratified with a homologous classification. Read More

Pediatric kidney abnormalities, such as urinary tract dilation (UTD), are common, and current reporting methods vary significantly. There's a need for more precise evaluation methods. Using automated 3D kidney volume measurements from ultrasound (US) offers an alterantive objective approach. Our aim is to evaluate the diagnostic potential of automated 3D kidney volume measurements for detecting and categorizing UTD, comparing their accuracy with clinical assessment. Read More

Congenital urethral polyps are a rare benign fibroepithelial lesion, typically arising from the verumontanum. We present a case of a 2 day old neonate undergoing renal ultrasound for follow up of prenatally diagnosed urinary tract dilation. Ultrasound demonstrated severe bilateral central and peripheral caliyectasis with parenchymal thinning, bilateral distal ureterectasis and marked bladder wall thickening. An echogenic soft tissue nodule was visualized at the bladder outlet. Subsequent VCUG showed a rounded filling defect intermittently located in the posterior urethra and bladder neck, suspicious for a diving mobile polyp. Transurethral resection of the polyp was performed. This case highlights an unusual cause of bladder outlet obstruction in neonates which can mimic the presentation and imaging appearance of posterior urethral valves. Read More

Urinary tract dilation (UTD) is a common finding in fetal and neonatal imaging, and accurate classification is essential for guiding management and determining prognosis. This educational exhibit provides a comprehensive review of the UTD classification system, with a focus on the findings on fetal ultrasound (US), fetal MRI and postnatal imaging. In addition to the classification system, we will explore the etiologies of UTD, including obstructive and non-obstructive causes such as vesicoureteral reflux, ureteropelvic junction obstruction, and posterior urethral valves. Special emphasis will be placed on the role of prenatal and postnatal imaging in monitoring progression and guiding management decisions, including when surgical intervention may be necessary. We aim to enhance the understanding of the diagnostic criteria for UTD, provide insight into the correlation between imaging findings and clinical outcomes, and equip pediatric radiologists with the tools to make informed management recommendations. This review will aid in the accurate diagnosis and treatment of UTD, ultimately improving outcomes for affected neonates. Read More
