Sonographic examination of the uropoietic tract (UPT) in neonates makes it possible to detect in time inborn disorders, in particular of the excretory pathways and to provide treatment before irreversible changes develop. The authors subject within the framework of screening of inborn developmental defects all neonates to sonographic examination of the UPT. In the submitted paper they evaluate a group of 2,103 children in the course of a one-year period; 89 neonates had changes as compared with normal findings. The largest group is formed (by as many as 57) by marginal dilatation of the hollow space. A dilated hollow system was recorded in 24 neonates and eight had different types of anomalies. By further comprehensive investigation conservative or surgical procedure is indicated to prevent further, possibly irreversible damage of the renal parenchyma.
