Pre-evacuation dilatation of the pregnant uterine cervix by Laminaria japonica.
Laminaria japonica was used as pre-dilator of the pregnant uterine cervix prior to termination of pregnancy in the first and second trimester. In the first trimester (6-11 weeks, n=26) no other method was used, while in the second trimester pharmacological stimulation--prostaglandin F2 alpha or the prostaglandin analogue Sulprostone was used after or simultaneously with the laminaria insertion (12-18 weeks n=34 and 40, respectively). The dilatatory effect of laminaria was an obvious help in termination of both first and second trimester pregnancies.

Examination of the uterine cervix by ultrasound in normal and pathologic pregnancy.
New possibilities of examination of the uterine cervix are provided by sonography in normal and pathologic pregnancy. Basic data of the ultrasonographic anatomy of the non pregnant uterine cervix is presented first: the length of the cervix as well as the diameters at the levels of external and internal os. ⋯ In this group shortening of the cervical length, opening of the internal os and the funnel, or hour-glass-like herniation of the fetal membranes were characteristic findings. The method seems to be suitable for the assessment of the effectivity of cerclage operations for cervical incompetence.
