To present three different subtypes of T-shaped uterus with the use of three-dimensional (3D) ultrasound imaging and hysteroscopy.
Three cases showing the different subtypes of T-shaped uterus.
3D ultrasound imaging and hysteroscopy.
Main Outcome Measure(s)
Distance between the interostial line and external uterine profile at the midcoronal plane of the uterus obtained with the use of transvaginal 3D ultrasound; delineation of the external uterine contour and the length of any existing internal indentation (defined as the distance between the interostial line and the indentation's edge at the cavity).
It is possible to identify three different subtypes of T-shaped uterus: the most common type of T-shaped uterus, with thick lateral walls and normal fundus (without septum or subseptum appereance) and interostial distance; the Y-shaped uterus, with thick lateral walls, fundal septum or subseptum, and reduced interostial distance; and the I-shaped uterus, with very thick lateral walls (even above the isthmus) and severe reduction of the interostial distance (tubular appearance of the whole uterus).
We solicit to investigate the occurrence of different T-shaped uterus subtypes in large cohorts, to evaluate whether they may have different reproductive outcomes and whether they may need different approaches for surgical correction through hysteroscopic metroplasty.
