What are the common types of abnormal uterine development? Four methods to help diagnose uterine developmental abnormalities

The uterus is an important part of the female body and plays an important role. We should also pay attention to the maintenance of the uterus in daily life. However, there may be abnormal conditions in the uterus, including abnormal uterine development.

Symptoms of abnormal uterine development

1. Menstrual abnormalities: Patients with congenital absence of uterus or primordial uterus have no menstruation. Patients with immature uterus may not have menstruation, but may experience symptoms such as oligomenorrhea, delayed menstruation, dysmenorrhea, and irregular physiological days. Patients with bicornuate or bicornuate uterus may experience excessive menstrual flow and prolonged physiological days.

2. Infertility: Dysplasia of the uterus, such as the absence of a uterus, primordial uterus, or immature uterus, is often one of the main causes of infertility.

3. Pathological pregnancy: There are many cases of miscarriage, premature birth, and abnormal fetal position after pregnancy. Occasionally, spontaneous uterine rupture during pregnancy may occur. If the fallopian tubes are unobstructed in the residual horn uterus, pregnant eggs can be implanted into the residual horn uterus, but the myometrium of the uterus is poorly developed and ruptured during pregnancy, with symptoms similar to ectopic pregnancy.

4. Pathology during and after delivery: Dysplasia of the uterine myometrium is common. Abnormal productivity during childbirth, difficulty in cervical dilation, difficult labor, and even uterine rupture. Transvaginal delivery may result in placenta retention, postpartum hemorrhage, or postpartum infection. After pregnancy, patients with dual uterus experience growth of the pregnant uterus, while non pregnant uterus is located in the uterine rectal fossa, resulting in sexual dystocia during delivery. Patients with dual uterus, bicornuate uterus, or mediastinal uterus may experience bleeding after childbirth due to the discharge of the decidua from the non pregnant uterine cavity.

Eight types of abnormal uterine development

1. Congenital absence of uterus: The accessory renal ducts on both sides extend horizontally towards the midline and converge. If development stops before reaching the midline, there is no uterus formation. Congenital absence of uterus often combined with congenital absence of vagina, but with normal fallopian tubes and ovaries. The diagnosis of the anus is equivalent to the location of the cervix and uterine body, without contact with the uterus and only with the folds of the peritoneum.

2. Primordial uterus: If the lateral extension of the accessory mesonephric ducts on both sides stops developing soon after reaching the centerline, this uterus is very small, without a uterine cavity, uterine cavity, or endometrium, so there is no menstruation.

3. Saddle shaped uterus: concave fundus, varying degrees.

4. Mediastinal uterus: The mediastinum is not absorbed, and the uterine body is divided into two halves, often accompanied by a vaginal mediastinum.

5. Double uterus: These two types of deformities are very similar. There are two uteruses, each with a fallopian tube, uterus, cervix, and vagina, which is rare.
