[Correlation of sonomorphologic placental maturity with the L/S ratio and creatinine level in the amniotic fluid]. / Zur Korrelation der sonomorphologischen Plazentareife mit der L/S-Ratio und dem Kreatininspiegel im Fruchtwasser.

ABSTRACT

With 184 L/S-ratio determinations and 132 creatinine determinations in amniotic fluid we tried to show a connection between these parameters and sonographically provable changes of placental structures. We found no relationship between placental grading and fetal lung and renal maturity by statistical processing of the results, considering gestational age. There is between L/S-ratio and creatinine determinations no statistical relationship, too.
