Consensus of best practice in intrauterine contraception in France

Uterine Artery Rupture Caused by IUD Extraction: A Case Report

It’s been 100 years since the first intrauterine device (IUD) was invented in Germany in 1920. IUDS are widely favored by women of childbearing age for their efficiency, convenience, cheapness, and variety of materials. According to incomplete statistics, about 26 million people worldwide will need to have their IUDS removed from 2015 to 2025 alone. With such a large case base, we have to pay attention to the safety of IUD removal. There are few international guidelines on IUD placement and removal. Therefore, this paper will report a case of uterine artery rupture caused by ring removal, and discuss the important steps of ring removal surgery, so as to enhance the attention of physicians to the standard and safety of ring removal and improve the quality of medical treatment.

The use of different doses levonorgestrel-releasing intrauterine system (LNG-IUS): real-world data from a multicenter Italian study

PURPOSE

Current research fails to adequately inform about the differential use of available levonorgestrel-releasing intrauterine systems (LNG-IUSs) in real life. Aim of our study was to compare the characteristics, satisfaction, continuation rates, and adverse effects between users of the high-dose LNG-IUS (52 mg) and of the low dose LNG-IUS (13.5 mg and 19.5 mg).

MATERIALS AND METHODS

A prospective cohort study was performed in two Services for Family Planning in normal menstruating women with the inclusion of all new prescriptions of LNG-IUS for contraception. Women were followed for a mean of 9.1 ± 2.6 months after placement.

RESULTS

109 women (mean age of 39.8 ± 8.7 years old) were included, 69.7% using a high dose LNG-IUS and 30.3% using a low dose LNG-IUS. Women with a low dose LNG-IUS were significantly younger, thinner, more nulliparous, with fewer vaginal deliveries and C-sections, with a lower menstrual flow length and with more previous use of short-acting reversible contraceptives (p < 0.05). LNG-IUS continuation was similar and very high at the last follow-up: 100 vs. 94.7% in the low and high dose LNG-IUS groups, respectively (p = 0.18). Satisfaction with treatment at the end of the study was similar between different LNG-IUS doses (p = 0.85), with 78.9% being satisfied/very satisfied. Bleeding patterns were significantly different between the two LNG-IUS doses (p < 0.0001). Diagnosis of dysfunctional cysts was more frequent in women with high dose compared to low dose LNG-IUS (22.2 vs. 12.1%), albeit not significantly.

CONCLUSIONS

We have shown a clear differential use of available LNG-IUS in clinical practice, both as baseline characteristics and as different outcomes, primarily for bleeding patterns. However, all these systems were associated with a very high rate of satisfaction and continuation.

Contemporary prescriptions pattern of different dose levonorgestrel-releasing intrauterine systems in an Italian service for family planning

OBJECTIVE

Current research informations fail to adequately inform about when levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg is used instead of other lower dose LNG-IUSs (13.5 and 19.5 mg) and other long-acting reversible contraceptives (LARCs) in clinical practice.

METHODS

A retrospective cohort study was performed in a third-level Service for Family Planning of Modena University hospital about all the first modern contraceptives prescriptions in the whole year 2019 performed by the same group of physicians. All women included underwent a detailed transvaginal ultrasound (TVUS) at prescription and a second evaluation within 3 months when they were still using the prescribed method.

RESULTS

To 69/160 (43.1%) women a short-acting reversible contraceptive (SARC), while to 91/160 (56.9%) a LARC was prescribed. Women with a LARC prescription were older than them with a short-acting (SARC) (p < .0001). Women with LNG-IUS 52 mg prescription were significantly the oldest (42.9 ± 5.3), while those with intrauterine copper device and lower dose LNG-IUS were of similar age (36.5 ± 7.3 and 34.9 ± 2.3), significantly lower (p < .005). Women with implant prescription had the same age as SARC, being the youngest (30.7 ± 8.9 and 31.0 ± 9.5) (p < .0001). Women with LNG-IUS 52 mg prescription mg presented with bigger uterine volume (p = .001). In multivariate analyses, the LNG-IUS 52 mg prescription was significantly linked only to age (OR 1.24; 95% CI 1.11-1.37, p < .0001) and presence of adenomyosis (OR 4.56; 95% CI 1.45-14.33, p = .009).

CONCLUSIONS

The use of LNG-IUS 52 mg instead of other LARCs is preferred for older women, with uteri of increased volume due to adenomyosis, suggesting a possible differential use of available LNG-IUSs in the contemporary clinical practice.
