“…This study demonstrated that pre-induction transvaginal cervical length measurement was a significant independent predictor of successful induction of labour (p<0.001). This was in agreement with previous studies which looked at the role of pre-induction cervical length assessment [ 11 , 14 , 16 – 20 ]. In addition, our analysis showed a high degree of correlation between cervical length and Bishop score with r -value of 0.745 ( p <0.001), hence providing evidence for the potential use of sonographic assessment of cervix as a method to predict successful induction.…”

Objective To evaluate the association between transvaginal ultrasound scan of cervix and Bishop’s score in predicting successful induction of labour, cut-off points and patients’ tolerability and acceptance for both procedures. Design A comparative clinical trial. Setting A tertiary hospital in Selangor, Malaysia. Participants 294 women planned for elective induction of labour for various indications were included. All women had transvaginal ultrasound to assess the cervical length and digital vaginal examination to assess the Bishop cervical scoring by separate investigators before induction of labour. Primary outcome measure To evaluate the association of the cervical length by transvaginal ultrasound scan and Bishop score in predicting successful induction of labour. Secondary outcome measure Variables associated with successful induction of labour and patients’ tolerability and acceptance for transvaginal ultrasound scan of cervix. Results There was no statistically significant difference among the vaginal and Caesarean delivery groups in terms of mean maternal age, height, weight, body mass index, ethnicity and gestational age at induction. Vaginal delivery occurred in 207 women (70.4%) and 87 women (29.6%) delivered via Caesarean section. There was a high degree of correlation between the cervical length and Bishop score (r-value 0.745; p <0.001). Sonographic assessment of cervical length demonstrated a comparable accuracy in comparison to Bishop score. Analysis using ROC curves noted an optimal cut-off value of ≤27mm for cervical length and Bishop score of ≥ 4, with a sensitivity of 69.1% vs 67%, specificity 60.9% vs 55%, and area under the curves (AUCs) of 0.672 and 0.643 respectively (p <0.001). Multivariate logistic regression analysis demonstrated that parity (OR 2.70), cervical length (OR 0.925), Bishop score (OR 1.272) and presence of funnelling (OR 3.292) were highly significant as independent predictors of success labour induction. Women also expressed significantly less discomfort with transvaginal ultrasound compared with digital vaginal examination. Conclusion Sonographic assessment of cervical measurement predicts the success of induction of labour with similar diagnostic accuracy with conventional Bishop score.

The article presents data on transvaginal sonographic assessment of cyclic changes in the endocervix in 78 women of reproductive age (19-35 years) without uterine pathologies. Among the examined women, 46 (59.0±5.6%) had a history of pregnancy (group I), 32 (41.0±5.6%) did not experience pregnancy (group II). The thickness of the endocervix in the late proliferative period in women of group I averaged 6.3±0.7 mm, and in group II – 9.1±1.2 mm, indicating a significant (p<0.05) difference between them . A decrease in the echogenicity of the endocervix on days 9-10 of the menstrual cycle was noted in 29 (63.0±7.1%) women in group I, and in 23 (71.9±7.9%) in group II. A moderate increase in the echogenicity of the endocervix was most often recorded on days 13-14 of the cycle - in 36 (78.3±6.1%) and 18 (56.3±8.8%) women (P<0.05), respectively. Isoechogenic endocervix was most often observed on days 21-23 of the cycle - in 26 (56.5±7.3%) and 25 (78.1±7.3%) women (P<0.05), respectively. Məqalədə reproduktiv yaşda olan 78 qadının endoserviksində baş verən dövri dəyişikliklərin transvaginal sonoqrafik müayinəsinin nəticələri təqdim edilmişdir. Qadınların yaşı 19-dan 35-ə qədər olmuşdur. Müayinə edilən qadınlardan 4 nəfərin (59,0±5,6%) anamnezində hamiləlik qeydə alınmış (I qrup), 32 nəfərdə (41,0±5,6%) hamiləlik olmamışdır (II qrup). Gecikmiş proliterativ dövrdə I qrupdakı qadınlarda endoserviksin qalınlığı 6,3±0,7 mm, II qrupdakı qadınlarda isə 9,1±1,2 mm olmuşdur (p<0,05). Menstruasiya dövrünün 9-10-cu günündə I qrupdakı qadınlardan 29 nəfərdə (63,0±7,1) endoserviksin exogenliyi azalmışdır, II qrupda isə belə nəticə qadınlardan 23 nəfərdə (71,9±7,9%) müşahidə edilmişdir. Menstruasiyanın 13-14-cü günündə nisbətən çox hallarda endoserviksin exogenliyinin orta dərəcəli artımı müşahidə edilmişdir - I qrupda 36 qadında (78,3±6,1%), ikinci qrupda 18 qadında (56,3±8,8%) (p<0,05). İzoexogen endoserviks isə mensrtuasiya dövrünün 21-23-cü günlərində nisbətən çox müşahidə edilmişdir - I qrupda 26 (56,5±7,3%), ikinci qrupda 25 (78,1±7,3) qadında (p<0,05). В статье представлены данные о трансвагинальной сонографической оценке циклических изменений в эндоцервиксе у 78 женщин репродуктивного возраста (19-35 лет) без патологий матки. Среди обследованных женщин у 46 (59,0±5,6%) в анамнезе были беременности (I группа), у 32 (41,0±5,6%) – беременность не наступала (II группа). Толщина эндоцервикса в позднем пролиферативном периоде у женщин I группы в среднем составила 6,3±0,7 мм, а во II группе – 9,1±1,2 мм, что показывает на достоверное (р<0,05) различие между ними. Снижение эхогенности эндоцервикса на 9-10-е дни менструального цикла отмечено у 29 (63,0±7,1%) женщин Iгруппы, у 23 (71,9±7,9%) – II группы. Умеренное повышение эхогенности эндоцервикса наиболее часто регистрировалась на 13-14-й дни цикла – у 36 (78,3±6,1%) и у 18 (56,3±8,8%) женщин (P<0,05), соответственно. Изоэхогенный эндоцервикс наиболее часто отмечался на 21-23-й дни цикла – у 26 (56,5±7,3%) и у 25 (78,1±7,3%) женщин (P<0,05), соответственно.
