ESTIMATION OF UTERINE VOLUME WITH ULTRASOUND IN WOMEN WITH ENDOMETRIAL CARCINOMA

In calculating uterine volume with ultrasound, it is necessary to calc ulate the volume of a parallelogram containing the uterus or to assume a specific shape for the uterus. The objective of this study was to d etermine how much (what percentage) of the parallelogram was actually occupied by the uterus without assuming any specific shape for the ute rus. Overall, the volume of the uterus occupies 63% of the volume of t he parallelogram. The uterus occupies a greater percentage of smaller parallelogram volumes than larger ones. The data also suggest that the concomitant presence of myomata may be responsible for the positive i ntercept of the regression line and therefore for the finding that sma ll uteri occupy more than 63% of the parallelogram volume.
