Can Uterocervical Angle Predict the Displacement of Copper Intrauterine Devices (T-Cu 380A)

Completed

• Conditions: Intrauterine Device
• Interventions: Diagnostic Test: uterocervical angle

• Registration Number: NCT05556421
• Lead Sponsor: Kanuni Sultan Suleyman Training and Research Hospital

Brief Summary

We conducted a case-control study between December 2020-June 2021 at Istanbul Health Sciences University Kanuni Sultan Suleyman Training and Research Hospital family planning outpatient clinics. One hundred and forty-three patients who had copper intrauterine devices (T Cu 380 A) inserted for contraception were evaluated between the 6th week to 5 years after insertion. Patients were divided into two groups according to their ultrasonographic examinations as "displaced" or "normal" positions. Uterocervical angles were measured of both groups by transvaginal ultrasonography and investigated whether the uterocervical angle had any effect in predicting the displacement of copper intrauterine devices.

Detailed Description

Family planning contains various protection methods, and copper intrauterine devices (IUD) are one of these. It has come forward among the contraception methods due to its long-acting effect, rapid return of fertility when discontinued, and ease of use. In worldwide usage, IUDs are the third most common method of contraception after tubal ligation and male condoms (1). When long-acting contraception methods were compared, the failure rate of the IUD was 0.8% per 100 women within one year (2). Factors affecting failure were; the application time of IUDs (3), application technique (4), uterus dimensions (5), endometrial cavity length (6), parity (7), and mode of delivery (8).

Uterocervical angle (UCA) is the angle measured in the triangle region between the anterior uterine segment and the cervical canal (9). UCA has been evaluated to predict the threat of preterm birth in national and international studies (9,10). In the literature, UCA has not been used in any studies within the scope of family planning. Our study aimed to investigate the feasibility of uterocervical angle measurements in predicting the dislocation of IUDs.

Arm && Interventions

Group	Intervention	Description
control group	uterocervical angle	normal intrauterine device position
case group	uterocervical angle	dislocated intrauterine device

Primary Outcome Measures

Name	Time	Method
uterocervical angle	6 months	Uterocervical angle (UCA) is the angle measured in the triangle region between the anterior uterine segment and the cervical canal

Secondary Outcome Measures

Name	Time	Method
endometrial cavity length	6 months	The length of the endometrial cavity (ECL) was determined as the canal extending from the beginning of the internal cervical os to the uterine fundus endometrium.
uterine volume	6 months	Uterine volume was accepted as ellipsoid with transvaginal ultrasonography device measured in transverse, longitudinal, and antero-posterior planes and volume was calculated in cm3.
