Feasibility and reproducibility of new technique for measurement of transverse diameter of levator ani muscle hiatus using two-dimensional transperineal ultrasound in nulliparous women at term.

Utilizing our described technique to measure the transverse diameter of the levator hiatus in the coronal view using 2D TPUS is not only feasible but also highly reproducible and accurate in nulliparous women at term of pregnancy. Moreover, it yields measurements that are comparable to those obtained in the reconstructed axial plane generated by 3D TPUS. This article is protected by copyright. All rights reserved.
