Abstract

To facilitate accurate and standard methods of reporting pathologic uterine corpus enlargement, we constructed a nomogram using the gravid uterine corpus volumes from five to 20 weeks' gestation in 186 patients. The volume was calculated by measuring the maximum length and anteropsterior and transverse diameters of the uterine corpus, and using the formula for the volume of a prolate ellipsoid: V=0.52 x (L x AP x T). Clinicians can use the nomogram for better understanding in assessing uterine volume.
