Background: In the selection of an appropriate IUD little consideration is placed on adequacy of fit. Properly fitting IUDs will likely lead to less adverse effects or patient discomfort resulting in enhanced continuation of use. Methods: A multicenter study conducted at 3 centers in 152 nulliparous women, to measure the maximal width of the uterine cavity using 3D ultrasound. Results: Measurements were performed by experienced sonographists. The mean width of the uterine cavity in the fundus was 21.6 mm (range 6.0 40.0 mm). The median value was 22.0 mm and the IQR 18.0 24.8 mm, respectively. Eighty-two % of women had a uterine cavity width between 15 mm and 28 mm, 40% <20 mm and 6.6% <15 mm, respectively. Discussion: Uterine cavities in nulliparous women are narrow and rarely wide enough to fit conventional IUDs. Gross discrepancy between the IUD and the uterine cavity leads to side effects (e.g., expulsion, embedment, bleeding, pain) and early discontinuation. Historically, devices too large for the uterine cavity have been routinely inserted which may account for their 5 year continuation rates being only 40 to 50%. Our study suggests that 3D sonography is a precise method to measure the width of the uterine cavity (although 2D may also be suitable) and may result in the selection of a suitable IUD to maximize continuation of use. Measurement of the cavity width is not necessary with a frameless IUD. Correspondence to: Dr. Dirk Wildemeersch, MD, PhD, F. Rooseveltlaan 43/44, 9000 Ghent, Belgium, E-mail: dirk@wildemeersch.com
