[Fetal-pelvic disproportion]

The files of 186 primiparous women with the diagnosis of fetal-pelvic disproportion were studied in order to depict maternal and fetal parameters determining the course of delivery. Three groups were compared. One group of women who delivered vaginally and two groups, that delivered by caesarean section, one with a dilated orifice and one with a non-dilated orifice. The maternal age, height and pelvic capaciousness as found by clinical examination were registered together with cardiotocography, birth weight, labour augmentation, instrumental delivery, fetal presentation, gestation age and the conjugata vera (measured at caesarian section). It was found that the maternal age and the gestational age were lower in the vaginal delivery group compared to the two caesarean section groups. There was no difference between all three groups with respect to the other parameters. On this basis it was concluded, that it was not possible to identify fetal-pelvic disproportion that would result in caesarean section in primiparous women.
