What are the female uterine malformations? Nine common classifications of female uterine malformations

The method of vaginal delivery for women, but the uterus is indeed the place to raise children, so the female uterus is very important. In today's society, many people do not know much about the uterus, and more people do not know what a malformed uterus is and what consequences it will have.

1. Congenital absence of uterus

Both sides of the accessory mesonephric duct extend horizontally to the midline. If the development stops before the midline, no uterus is formed. Congenital absence of uterus usually combines with congenital absence of vagina, but may have normal fallopian tubes and ovaries.

Anal diagnosis is equivalent to the cervix and uterine body, and cannot touch the uterus, only the peritoneal folds.

2. Primordial uterus

If both sides of the accessory mesonephric duct extend horizontally to the midline and stop developing soon, then this kind of uterus is very small, there is no uterine cavity or uterine cavity, and there is no endometrial growth, so there is no menstruation.

3. Immature uterus

From late pregnancy or fetal birth to any period before puberty, the uterus will stop developing, and various degrees of uterine underdevelopment may occur. The cervix of this type of uterus is relatively long, mostly conical, with a smaller outer opening; The uterine body is smaller than normal and often exhibits extreme forward or backward flexion. Those who bend forward often have underdeveloped anterior walls, while those who bend backward often have underdeveloped posterior walls. Childish uterus can cause dysmenorrhea, oligomenorrhea, amenorrhea, or infertility

4. Uniangular uterus

One side of the accessory mesonephric duct is well developed, forming a well developed monocornical uterus with normal fallopian tubes. The development of the contralateral accessory mesonephric duct completely stopped. The function of the unicorn uterus may be normal.

If pregnant, pregnancy and childbirth can be normal, but they may also lead to miscarriage or difficult childbirth.

5. Residual horn uterus

One side of the accessory mesonephric duct develops normally, and the other side stagnates, forming a rudimentary horn uterus of varying degrees. Most of them are connected to the other side of the single horn uterus only through fiber bundles.

Due to the lack of function in the endometrium, it is often asymptomatic. If functional, after puberty there will be periodic lower abdominal pain and other menstrual blood retention symptoms.

Some have narrow lumens connected to the opposite uterus, in which case residual horn uterine pregnancy can occur, with symptoms such as interstitial pregnancy of the fallopian tube, often lasting from 3 to 4 months of pregnancy, and severe internal bleeding.

6. Blind horn uterus

Both sides of the accessory mesonephric duct are well developed, but one side of the uterine horn does not communicate with the vagina, forming a blind horn uterus. After puberty, menstruation occurs and there is periodic lower abdominal pain, which is becoming increasingly severe and has not been detected for a long time.
