About this study
The investigators aim to compare elasticity of the uterine cervix in singleton and twin pregnancies of similar gestational age.
Read the detailed description
Softening of the uterine cervix occurs during pregnancy.There is a possibility that this process occurs earlier in twin versus singleton pregnancies.The softening of the cervix is reflected by the level of its elasticity which can be measured sonoelastographically. A two dimension image of the cervix is obtained in the midsagittal section and the length is noted. A 2nd sonoelastography image is obtained before pressure is applied with the transducer in the area of the internal os and a third sonoelastography image is obtained until no more shortening of the anterior-posterior diameter is observed.Elastography measurements of the internal os are performed using a color map: red (soft), yellow (medium soft), blue (medium hard) and purple (hard) before and after the application of strain.The change between the color maps before and after strain application in singleton pregnancies will be compared to the change in twin pregnancies of similar gestational age.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 23 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Rami Aviram, MD (972544944862, rami.aviram@clalit.org.il), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Comparison of elasticity levels in singleton and twin pregnancies (Elastographic measurements of the internal os) (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2015.
