Objective. To evaluate the possibility of geometric modeling in increasing the efficiency of calculating true conjugate of pelvis.
Materials and methods. During the first stage of the study, a mathematical relationship was determined by geometric modeling of the ultrasound pelvimetry results; this relationship could hypothetically reduce the error in calculating the true conjugate. The second stage included the prospective analysis of anthropometric parameters that allowed us to calculate the value of the true conjugate of the pelvic cavity. Ultrasonic pelvimetry was used as the gold standard that objectively reflected the value of the true conjugate.
Results. The relative average error in calculating the true conjugate with the help of standard methods was 4.9%, while using the developed method it was 1.0%.
Conclusion. The results of the obtained studies confirmed the high significance of geometric modeling in improving the efficiency of calculating the true conjugate of the pelvic cavity.
