RESUMO

Introduction and objectives: Due to the controversies about the necessity of new shorter intrauterine devices (IUDs) for nulliparous women in order to reduce expulsion rate, the length of the endometrial cavity was measured in women with different parities by uterine sound and ultrasound. Materials and methods: We evaluated 570 women (17 to 52 years old) distributed on 260 nulliparous and 310 parous. Results: The difference between mean values obtained by the uterine sound and by ultrasound was 0.28 cm. The length of the endometrial cavity on nulliparous and parous women was 3.84 ± 0.03 and 4.25 ± 0.03, respectively (p <0.001) when assessed by the uterine sound and 3.70 ± 0.03 and 3.84 ± 0.03 (mean ± SEM), respectively when assessed by ultrasound (p = 0.006). Conclusions: The endometrial cavity length evaluated by the two techniques showed a mean value greater than 3.6 cm which is the length of the most worldwide available IUD (TCu380A) and the levonorgestrel-releasing intrauterine system (LNG-IUS). This allows us to speculate that there is no rationale to develop new IUDs with shorter length, because the actual models are fitted to most of the women, including nulliparous
