People often expect “double” gifts; double gifts, buy one get one free, twins, or even a double jackpot …… But not all “pairs” bring people “joy”. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Normally, a double uterus does not cause much trouble for a woman, as long as both uteruses are normal or only one is normal, the function of pregnancy can be achieved. However, for patients with adenomyosis, a double uterus can bring double the pain because both uteruses will have adenomyosis focal tissues, and the focal tissues in both uteruses will become congested, edematous and bleeding during monthly menstruation, which can cause menstrual pain. 14 years ago, the dysmenorrhea worsened with no obvious cause, so she went to the local hospital for ultrasound examination and found double uterus and pelvic mass, so she underwent surgery to treat the pelvic mass, the details of which are not detailed. 5 years ago, the dysmenorrhea worsened with anal swelling and pain on the right side radiated to the right lower limb, and she went to the local hospital for ultrasound examination and found adenomyosis. One year ago, the dysmenorrhea worsened again and she was given 8-10 indomethacin suppositories at the local hospital to relieve the dysmenorrhea. Adenomyosis focal tissue excavated during surgery + left uterus excised Our adenomyosis hysterectomy team performed surgical treatment to preserve the uterus and excavate the focal tissue. The left side of her uterus was found to be a “primordial uterus” which could not perform the function of childbirth, so the left side of her uterus was removed and only the right side of the uterus of normal size was preserved. Two years after the surgery, the uterus can be evaluated for recovery to see if she can undergo trial pregnancy or in vitro fertilization, and if she is lucky, she can have a baby on her own.
