title: [Comparison between pre- and postnatal echographic screening of malformative uropathies].
abstract: OBJECTIVE
  The aim of this study has been to compare the validity of postnatal echographic screening in respect of prenatal echography in early diagnosis of malformative uropathies (MU).
  
  
  METHODS
  In 6578 infants, who have been submitted to fetal echography, and to a postnatal screening of MU in our Neonatal Service of Echography (University of Messina), we have compared the diagnostic agreement of prenatal with postnatal echography.
  
  
  RESULTS
  Our comparison demonstrates that, in respect of postnatal screening, only 35.71% of pyelectasies and 73.17% of hydronephrosis have been diagnosed by fetal echography, and, in particular, only 18.75% of no-dilated MU.
  
  
  CONCLUSIONS
  These data confirm that, in our country, the postnatal screening of MU has still significance and suggest that, before excluding this screening, it is necessary to verify everywhere the validity of fetal echography.
