title: [Validity of ultrasound fetometry in the diagnosis of a large fetus during screening].
abstract: The purpose of the study was to assess the validity of fetometry in the diagnosis of a large fetus during screening. Eight hundred and sixty-five case histories of large fetal labors were analyzed, by determining the assumed fetal mass by ultrasound fetometry before labor. The studies have demonstrated that the validity of fetometry in the diagnosis of a large fetus was not greater than 73%. This was caused by methodical errors, the specific features of different procedures for calculating the assumed fetal mass, and the heterogeneity of anthropometric parameters of large fetuses.
  
  
  CONCLUSIONS
  it is necessary to study additional possibilities of enhancing the validity of fetometry in the determination of a large fetus during screening and to continue a search for optimal methods of calculating the assumed fetal mass.
