Normograms in Prenatal Life of Stomach and Urinary Bladder in the Second and Third Trimesters of Pregnancy.

The normograms for the stomach, urinary bladder and the stomach to urinary bladder index prepared based on our study group can contribute to an improvement in the accuracy of examination and provide an unified organization of the description of fetuses. These normograms constitute an additional marker for the assessment of fetal condition. A clear disproportion in the size of the urinary bladder and stomach can be helpful in terms of paying more attention to fetuses with untypical features in screening centers.
