Introduction: The diagnosis of cervical incompetence is often retrospective. It has become one of the obstetric challenges because of the lack of uniform prospective diagnostic criteria. Ultrasonography is an invaluable aid in the diagnosis of cervical incompetence as it is safe and noninvasive. The present study focused on changes in cervical parameters and relationship of cervical parameters with pregnancy outcome.
Materials and Method: Total 160 cases - primigravidas were studied for the ultrasonographic parameters of cervix during the study period. Institutional Ethical committee approval was taken before beginning of the study. Patient were subjected to ultrasonographic study between 14 to 22 weeks for the first time, then serial ultrasonography was done monthly mainly for cervical parameters and if required, cervical encerclage was done.
Result: The incidence of cervical incompetence found in the present study was 1.25%. Mean cervical length was 3.49±0.53cm and mean diameter of internal os was 3.75 ±1.5mm. Shorter the cervical length, lesser is the gestational age at the time of delivery.
Conclusion: We conclude that, cervical length and diameter of internal OS are very important cervical parameters for the cervical incompetence.
