Abstract:Objective By measuring the actual cervix morphology and volume, to evaluate the accuracy of transvaginal two-dimensional ultrasound in measuring the cervical morphology and volume.Methods A total of 43 hysterectomy patients who were operated in the Second Affiliated Hospital of Chongqing Medical University from September 2016 to March 2017 were included in the study;before the hysterectomy, the cervical anteroposterior diameters, transverse diameters and longitudinal diameters were measured by transvaginal two-dimensional ultrasound, and after the operation, the anteroposterior diameters, transverse diameters and longitudinal diameters were measured by vernier caliper;used the displacement volume of normal saline to measure the actual cervical volume;finally all the results were statistically analyzed.Results There were no significant difference between the actual transverse diameters measured by vernier caliper and theoretic transverse diameters measured by two-dimensional ultrasound (P>0.05);there was no significant difference between the longitudinal diameters and theoretic longitudinal diameters (P>0.05);the actual anteroposterior diameters of the cervix were greater than those measured by two-dimensional ultrasound (P<0.05). The actual volume of the cervix was[7.5-34.5 (17.74±5.78) ]cm3, while the theoretic volume of cervix by two-dimensional ultrasound was[6.68-35.85 (17.68±6.20) ]cm3. Comparing the theoretical volume with the actual volume of cervix, there was no difference (P>0.05).Conclusion The two-dimensional ultrasound has a high accuracy in the measurement of cervical morphology and actual volume.
