“…12,17,18 Our study found that women with a greater LTD had a higher risk of expulsion or displacement among MLCu375 or TCu380A users. To the best of our knowledge, few studies have investigated the association between expulsion and LTD, as measured by ultrasound.…”

Objective To evaluate the effect of the dimensions of the uterine cavity in relation to the expulsion, or removal for displacement, of intrauterine devices (IUDs) MLCu375 and TCu380A.Design A case-control study nested in a multicentre clinical trial.Setting Eighteen family planning clinics in China.Population Forty-eight pairs of TCu380A users and 118 pairs of MLCu375 users.Methods The women were classified as cases if IUD expulsion or displacement occurred during the first year of follow-up after insertion. One control was randomly selected for each case matched by IUD model, centre, age, service provider for insertion, and date of insertion. Axial length of the uterine cavity (LUC) and the largest transverse diameter of the coronal section of the uterine cavity (LTD) were measured using abdominal ultrasound. We used multivariate conditional logistic regressions to estimate the adjusted odds ratios (aORs) of expulsions or displacements among women with different sizes of uterine cavity according to the quartile of LUC and LTD, respectively.Results Among MLCu375 users, women with LTD ≥ 27 mm had a higher risk of expulsion or displacement (aOR 2.40; 95% confidence interval, 95% CI, 1.02-5.63), after adjusting for the volume of menstrual flow, dysmenorrhoea, parity, uterine position, MLCu375 type, and LUC. Among TCu380A users, the association between LTD ≥ 37 mm and expulsion or displacement (aOR 4.98; 95% CI 1.01-22.49) was statistically significant, after adjusting for LUC and potential confounding factors.

“…The expulsion rate was higher for women with an endometrial cavity length equal to or greater than 45 mm (p<0.01) for one or two years. On the other hand, Bahamondes MV et al [20] evaluated the correlation between endometrial cavity length and expulsion rate in acceptors of the TCu380A intrauterine device (IUD) or the levonorgestrel-releasing intrauterine system (LNG-IUS). Their results do not support the hypothesis of an association between uterine length and risk of intrauterine contraceptive expulsion [20].…”

In a study, when cases were compared to nonpregnant controls with IUD, the results showed that uterine position and hysterometric measurements were not associated with an increased risk of pregnancy.…”

Aim. The aim of this study was to detect the relationship between IUD failure and some factors such as length of tail, IUD experience, education level, utilization period, gravidy, parity, age and length of uterine cavity. Methods. Our study groups included 48 patients who were randomly admitted to our clinic for problematic IUD and 30 normal patients without any complaints who were admitted to our clinic with out of date IUD who wanted new IUD insertion or desired to become pregnant as control group. Both groups were evaluated for the demographic characteristics such as education level, history of abortion, menstrual regulation, and type of delivery, IUD experience and blood count, duration of IUD use, length of tail, type of IUD, and length of uterine cavity. Results. We detected statistically significant results for length of cavity, length of tail, education level and IUD experience. Conclusion. We are in the opinion that length of uterine cavity, length of IUD tail, educational level and IUD experience are associated with IUD failure. Keywords: Contraception, intrauterine devices, copper ÖzetAmaç. Bu çalışmanın amacı RİA kullanımında başarısızlık ile rahim kavite uzunluğu, eğitim seviyesi, RİA ipinin uzunluğu, kullanım süresi, RİA tecrübesi, gravida, parite ve yaş gibi bazı faktörlerin ilişkisinin incelenmesidir. Yöntemler. Kliniğimize rastgele başvuran problemli spirali olan 48 hasta bizim çalışma gurubumuzu oluşturmuştur ve hiçbir yakınması olmayan spiralinin günü geçtiği için yeni spiral isteyen veya bebek yapmayı planlayan 30 hasta kontrol gurubumuzu oluşturmuştur. Her iki gurup demografik özellikler, eğitim seviyesi, düşük öyküsü, adet düzeni, doğum şekli, RİA tecrübesi ve kan sayımı, spiralin kullanım süresi, tipi, kuyruk uzunluğu ve rahim kavitesinin uzunluğu açısından karşılaştırılmıştır. Bulgular. RİA ipinin uzunluğu, kavite uzunluğu, eğitim seviyeleri ve RİA tecrübesi açısından istatistiksel olarak anlamlı sonuçlar saptadık. Sonuç. Biz RİA ipinin uzunluğu, kavite uzunluğu, eğitim seviyeleri ve RİA tecrübesinin spiral kullanımındaki başarısızlıkla ilişkili olduğu düşüncesindeyiz.
