[Value and limits of estrioluria in cases of retarded fetal growth]

On the basis of personal experience of 56 cases of retarded intra-uterine growth (RIUG) followed during the course of pregnancy by means of repeated estriol determinations (213 values), the authors note that : In 2/3 of the cases the urinary estriol level was higher than the lower limit of normality. The urinary estriol levels were not related to the severity of the RIUG. The estriol level has a limited value in the diagnosis of RIUG. The authors emphasize the prognostic value of the curves of estrioluria in this pathology and propose a course of obstetrical management based on interpretation of the curves.
