Brief summary

İn this study Study; Between August 2018 and August 2019, the Ministry of Health, Medeniyet University, Göztepe Training and Research Hospital, Gynecology and Obstetrics Clinic Will be Included for Routine Control Purposes, Single Pregnancies Between 16-24 Weeks and no Known Risk Factors for Preterm Delivery . Each Participant Will be Given Written and Verbal Information About the Work and Will be Informed. Uterocervical Angle Measurement; Dorsolithotomy, Using a Sterilized Vaginal Ultrasonic Probe. It Will be Seen That the Distance Between the Internal Cervical os and the External Cervical os is Inclusive of the Cervical Isthmus That Can be Seen With the Anterior Uterine Wall. The First Line Will be Drawn Between the Internal Cervical os and the External Cervical os. The Second Line Will be Drawn as Passing Through the Internal Cervical Ostia, Parallel to the Anterior Uterine Wall. The Angle Between the Two Lines on the Internal Cervical Vertebra Will be Measured. Patients Will be Followed up Until the End of the 37th Gestational Week. The Gestation Week They Are Giving Birth Will be Recorded. Patients Were Then Classified as Before and After 37 Gestational Weeks and Uterocervical Angle Measurements Between 16-24 Gestational Weeks Were Compared.

Interventions

DIAGNOSTIC_TESTmeasurement of uterocervical angle

We will measure between internal cervikal os and external cervical os. After we will draw a line between anterior uterine wall and internal cervical os. Then we will measure angle between two lines
