“…Another narrative review of prospective and retrospective studies published between 1995 and 2022 [62] shows that the diversity of design and risk factors considered in each study makes it very difficult to analyze the evidence on the strength of the association between HC use and BC. This low quality of evidence on BC risk is outweighed by the reported benefits to women's health in addition to the effectiveness of any contraception method in preventing pregnancy [63,64]. We, therefore, suggest that contraceptive counseling follows national or WHO recommendations [65] based on selection criteria according to a woman's health and her reproductive needs, while considering the followup of populations at risk of any complication associated with the selected method and applying the recommendations of each country for the early detection of BC.…”

This study aims to summarize evidence from observational studies about the lifetime use of HC and the risk of BC in women of reproductive age. The PubMed, Cochrane, and EMBASE databases were searched for observational studies published from 2015 to February 2022. Meta-analyses were performed using adjusted odds ratios and relative risks with a random-effects model using the I2 statistic to quantify the heterogeneity among studies. Of the 724 studies identified, 650 were screened for title/abstract selection, 60 were selected for full-text revision, and 22 were included in the meta-analysis. Of these, 19 were case-control studies and 3 were cohort studies. The results of the meta-analysis indicate a significantly higher risk of developing BC in ever users of HC (pooled OR = 1.33; 95% CI = 1.19 to 1.49). This effect is larger in the subgroups of case-control studies (pooled OR = 1.44, 95% CI = 1.21 to 1.70) and in the subgroup of studies that strictly define menopausal status (pooled OR = 1.48; 95% CI, 1.10 to 2.00). Although our meta-analysis of observational studies (cohort and case-control) suggests a significantly increased overall risk of BC in users or ever-users of modern hormonal contraceptives, the high heterogeneity among studies (>70%) related to differences in study design, measurement of variables, confounders, among other factors, as well as publication biases should be considered when interpreting our results.

“…Indwelling IUDs are considered as a relatively safe, effective, simple, economical and reversible method of contraception. 1 For 40% of women 3 of childbearing age, an IUD has become the contraceptive of choice. Common adverse reactions and complications associated with IUD implantation include bleeding, uterine perforation and ectopic pregnancy, infection, dysmenorrhea, abnormal menstrual volume, infectious abortion, and endometrial tumors.…”

Four cases of heterotopia of an intrauterine device embedded in the bladder muscular layer causing cystolithiasis: case report and review of the literature

et al. 2021

Family planning is a basic national policy in China. An intrauterine device (IUD) is an important method of achieving family planning owing to its high safety, low cost, and convenient use. The indwelling birth control ring has no obvious adverse effects on the sexual life of women after the operation, and the process is reversible. This ring can be removed for women who want to have children again. There are approximately 100 million women with IUDs worldwide, with approximately 80 million in China. This finding accounts for approximately 40% of women of childbearing age in China. Although an IUD is safe, the invasive operation inevitably leads to complications, such as pelvic infection, abnormal menstruation, and damage to adjacent organs. Among them, ectopic bladder stone formation is a rare complication, but several related cases have been reported. We report four cases of heterotopia of an IUD and cystolithiasis, with diagnosis based on the medical history, clinical manifestations, imaging, and cystoscopic findings. The four patients with ectopic IUDs were treated with cystoscopy combined with laparoscopy (or hysteroscopy). We describe the process of diagnosis and treatment of our patients, and the related literature on an ectopic IUD is reviewed.

“…Cependant, la taille de l'échantillon de l'étude étant limitée, ceux-ci nécessitent d'être interprétés avec prudence. Les recommandations françaises et celles de l'Organisation mondiale de la santé (OMS) s'accordent pour les préconisations de contraception dans le contexte de l'obésité [33,34,47] (Figures 2 et 3). Pour une femme de moins de 35 ans, sans facteur de risque cardio-vasculaire associé, et présentant un IMC importante : environ 70 % de l'excès de corpulence, correspondant à une perte de 20 à 30 % du poids corporel, sur le long terme [35][36][37].…”

La question de l’influence de l’obésité sur la contraception peut être envisagée sous plusieurs angles : comme facteur de risque d’échec d’une contraception hormonale ; comme facteur de risque cardio-vasculaire, pouvant majorer ce risque lors de l’association à une contraception hormonale. Les modifications métaboliques observées au cours de l’obésité et la masse corporelle plus importante des femmes présentant une obésité peuvent en effet être à l’origine d’une réduction de l’efficacité de la contraception hormonale. Néanmoins, les données, mêmes peu nombreuses, laissent penser que l’efficacité de la plupart des méthodes de contraception n’est a priori pas diminuée chez ces femmes. La chirurgie bariatrique, utilisée pour remédier à l’obésité, constitue une situation complexe, qui impose une contraception dans la première année post-opératoire afin d’éviter toute grossesse. Si la technique chirurgicale induit une malabsorption (comme le bypass), toute contraception administrée par voie orale verra son efficacité fortement diminuée et sera donc déconseillée en raison d’un haut risque d’échec.
