[Caval urography in children with large and giant omphalocele].

The paper presents the results of using a caval urographic procedure in 37 children with large and giant omphalocele prior to the radical operation displacement of organs from hernial protrusion into the abdominal cavity. High percentages (54 and 96%) of changes in the vena cava and urinary tract, respectively, make the author recommend this procedure for all children with this congenital anomaly. The findings help surgeons choose treatment policy and avoid undesirable complications.
