There is a possibility of recurrence of hydrosalpinx with laparoscopic surgery, but there are individual differences. Hydrosalpinx is caused by adhesions at the umbilical end of the fallopian tubes due to inflammation of the tubes. Even after surgery for tubal stoma and molding, there will be trauma and recurrence is easy. It is recommended to try to get pregnant within six months to one year after surgery, which is the best time to get pregnant, because the longer the time after surgery, the higher the chance of recurrence. Patients with tubal effusion after infertility surgery require pregnancy as soon as possible, preferably within six months. If they cannot conceive after one year, assisted reproduction is recommended. In women who have recurrence of hydrocele and require fertility, laparoscopic surgery is not recommended and assisted reproduction is recommended instead. In addition, to avoid recurrence of hydrosalpinx, it is important to pay attention to postoperative care and diet so as not to cause secondary episodic infection. Many tubal effusions are due to episodic infections, or tuberculosis of the fallopian tubes or pelvic tuberculosis. Therefore, it is important to avoid these conditions.
