Ultrasound Biometry of the Non-pregnant Uterus in Beninese Women

Abstract

Uterus is a female organ that undergoes enormous variations during her genital life. To study the dimensions of the normal uterine biometry of Beninese women outside pregnancy. This study was a cross-sectional prospective study from November 05, 2009 to July 31, 2010. It involved 119 Beninese women aged 13 to 70 years identified in two ultrasonography services, namely Autonomous Centre of Radiology (CAR) of EPAC-UAC (Polytechnic School of Abomey Calavi) and the Principal Hospital of Ouidah. The study focused on women who came to ACR to undergo pelvic ultrasound. Included in our sample, women who did not present uterine pathologies such as fibroma, synechia, polyp, cancer, with no uterine scar on ultrasound. Excluded from the study, pregnant women, women who had a cesarean section. Measurements were made in longitudinal and transverse sections by supra-pelvic ultrasound. Uterine length and its thickness were performed on the longitudinal section and its width on the cross-section. The average size of the Beninese woman's uterus were: length=86.17 mm; width=49.24 mm; thickness=37.42 mm. According to the parity we have for nulliparous (length=80.08 mm; width=48.02 mm; thicknes=35.70 mm), primiparous (length=88.47 mm; width=48.24 mm; thickness=37.47 mm), multiparous (length=99.33 mm; width=52.43 mm; thickness=41.50 mm). The dimensions of the non-pregnant uterus of Beninese women were 86.17mm (lC 95%: 83.09 - 92.40) for the length, 49.24 mm (95% CI: 47.45 - 51.02) for the width and 37.42 (IC 95%: 36.02 38.81). All these dimensions increase with parity. Parity is a factor which contribute to the uterine size variation
