[Obstetrical prognosis by x-ray pelvimetry].

For a period of 44 months 87 deliveries were analyzed by roentgenological pelvimetry, performed by a method, improved by the authors (1982). The relative part of pregnant women with roentgenological pelvimetry was 1.1%.

[The determination of the probable term of delivery].

The full-term infants born during the leap year of 1988 in the obstetric-gynecological complex in the town of Dobrich were 2434, but the infants born according to the formula of Negele within the defined term--14 days were 2038. Most women were delivered of infants before the term. Standardization of parturients before and after term is made after estimated term with addition of 5 days to the last menses as the number of deliveries is increased as well.
