[The urinary excretion of pregnanediol during pregnancy determined by gas-liquid chromatography. III. Its relation with the obstetric results (author's transl)].
269 determinations of urinary pregnanediol by gas-liquid chromatography were made in 140 patients during pregnancy. A relation between the pregnandioluria and the fetal results (adequacy of the weight to gestational age, Apgar score at one and five minutes of birth, umbilical artery blood PH and perinatal mortality) as well as the global evaluation of the placenta (macroscopic aspect, vascular index of Kawai et al. and Scott and Jordan index) was studied. The results show that in the cases with fetal pathology (small for date, depression, acidosis, perinatal death) as well as in the cases with placental pathology, the values of pregnanediol were significantly decreased from the first months of pregnancy, which indicate that the placental insufficiency is a very precoz chronic process and on the other hand, that the determination of urinary pregnanediol is a good method for its detection.
