Representative uterine septa from two patients who were treated with hysteroscopic metroplasty and no antiadhesion prophylaxis. Top row (33-year-old woman): (A-1) Preoperative three-dimensional sonohysterography showing the uterine width <3.5 cm and surface area <4.5 cm². (B-1) Myometrial thickness achieved at the completion of surgery (three- or four-dimensional transrectal ultrasonography). (C-1) After healing, RS was absent. Bottom row (30-year-old woman): (A-2) Preoperative three-dimensional sonohysterography showing uterine width >3.5 cm and surface area >4.5 cm²; the length was similar to other patient in (A-1). (B-2) Myometrial thickness achieved at the completion of surgery (three- or four-dimensional transrectal ultrasonography). A similar myometrial thickness was achieved as in other patient in (B-1). (C-2) After healing, RS was present.
