[Malformations of the urinary tract in neonates. Current status of imaging procedures]

Malformations of the urinary tract are one of the most common types of anomalies in the neonatal period. Approximately 15-20% of all prenatally detected malformations require acute postnatal imaging. Sonography is the primary imaging modality in the evaluation of nephro-urologic problems in infancy. Hydronephrosis represents the most common pathology, followed by multicystic-dysplastic kidney.

The result of the sonographic examination directs further imaging. An adequate diagnostic algorithm is decisive for accurate diagnosis, for the appropriate therapeutic regimen and for the prognosis of the patients.
