The effect of parity on cervical two- and three-dimensional measurements

Research output: Contribution to journalMeeting Abstractpeer-review

Abstract

Objectives
To compare cervical volume, length, anteroposterior (AP) and width (LL) dimensions in nulliparous and parous women after vaginal delivery.

Methods
Cervical three-dimensional (3D) measurements were obtained by pre-defined criteria during the gynecological ultrasound and stored in an archive. Cervical volume was acquired by the gold standard for 3D measurements - Virtual Organ Computer-Aided Analysis software (V VOCAL). Cervical length was measured from internal cervical os to external cervical os. AP and LL measurements were measured in cervical canals middle portion, perpendicular to each other (image 1). Cervical volumes were compared using the Man-Whitney test, cervical length, LL and AP diameters were compared using T-test, our p-value for statistical significance was p < 0.001.

Results
We included 86 participants, nulliparas (n = 40) and multiparas (n = 46), women after Caesarean sections were excluded. Comparing nulliparous and parous women's V VOCAL, multiparous women had larger cervical volume (median 25.68 vs 20.27 cm3, p < .000) and larger AP (mean 3.15 vs 2.78 cm, p < .000) dimensions. Parity had no effect on cervical length measurement's (mean 2.92 vs 3.08 cm, p = 0.29) and LL (mean 3.13 vs 3.15 cm, p = 0.8) dimensions.

Conclusions
Multiparous women have larger cervical volumes and AP cervical dimensions compared to nulliparous women. Our data suggest that parity has no effect on the cervical length and LL dimensions.
