Diagnostic accuracy of three-dimensional sonohysterography compared with office hysteroscopy and its interrater/intrarater agreement in uterine cavity assessment after hysteroscopic metroplasty

3D-SIS demonstrated substantial interrater/intrarater agreement for the postoperative evaluation of the uterine cavity, being as diagnostically accurate as hysteroscopy. The use of second-look hysteroscopy may be limited to cases that require reoperation.
