[The urinary excretion of pregnanediol during pregnancy determined by gas-liquid chromatography. II. Its relation with other parameters controling pregnancy (author's transl)].
The relation between the urinary pregnanediol determined by gas-liquid chromatography during pregnancy, with ultrasonic findings (biparietal diameter, thickness and echorrefringency of the placenta and the appreciated quantity of amniotic fluid), with biochemical parameters of control of pregnancy (beta-glucoronidase, total and thermostable alkaline phosphatase), with amnioscopic findings, and with several studied parameters of the amniotic fluid by amniocentesis, were studied. A good relation exists with the parameters which denote placentary insufficiency and fetal risk (irregularity in the homogeneity of the placenta, elevation of the total and thermostable alkaline phosphatase, positive amnioscopy) and also with those that are related with fetal maturity (biparietal diameter, shake test, organge cells, creatinine in amniotic fluid, etc.). These results indicate that the determination of urinary pregnanediol can be one of the tests controlling the normal and pathological pregnancies, being useful in the detection of fetal risk and the diagnosis of the intrauterine fetal maturity.
