Ultrasonographic uterine dimensions in non-pregnant adult females at Agbor Delta State; establishment of norms

Abstract

This study evaluated the normal uterine size (longitudinal, transverse and anteroposterior dimensions) of the non-pregnant uterus with  use of ultrasonography. The study was carried out amongst women in Ika South Delta State, Nigeria. Uterine dimensions were  determined by real time trans-abdominal pelvic ultrasound scan in Agbor, Delta State. A cross-sectional study of normal uterine size of  300 women aged 17-47 years was conducted by ultrasonographic measurements. The women were divided into three groups - 100  nulligravida, 100 primigravida and 100 multigravida women according to gravidity. Findings showed that mean uterine sizes of 56.1 mm x  46.7 mm x 41.8 mm for nulligravida women, 63.0mm x 52.0mm x 46.3mm for primigravida, 70.0mm x 56.4mm x 50.9mm for  multigravida women and 63.0mm x 51.7mm x 46.3mm for overall total. Uterine size in non-pregnant women was significantly correlated  with gravidity and the study also predicted uterine size using linear multiple regression lines.
