Step 1: A septate uterus is best treated by removing the septum, and the modern, preferred technique is hysteroscopic (transcervical) resection of the septum.
Step 2: Hysteroscopic metroplasty has a high success rate (about 80 to 89 percent), a short hospital stay, and low postoperative morbidity such as infection or adhesions.
Step 3: Because the uterus is not opened, the subsequent chance of vaginal delivery is high, unlike abdominal metroplasty where a cesarean section is mandatory.
Step 4: The abdominal procedures, Strassmann, Jones, and Tompkins metroplasty, are older open operations now largely replaced. So the best option is transcervical hysteroscopic resection of the septum.
