Study Arms:
- IUB dilatation therapy (Type: EXPERIMENTAL): The patient will have Foley-catheter intrauterine balloon dilatation 2 weeks and 6 weeks after hysteroscopic adhesiolysis. A second-look hysteroscopy will be carried out in the early proliferative phase 4 weeks after the surgery and third-look hysteroscopy will be carried out 8 weeks after the surgery.
- control group (Type: NO_INTERVENTION): Patient will not undergo any balloon therapy. A second-look hysteroscopy will be carried out in the early proliferative phase 4 weeks after the surgery and third-look hysteroscopy will be carried out 8 weeks after the surgery.

Based on this trial design, predict the completion outcome and termination type (if applicable).
