What types of uterine developmental abnormalities are classified? There are six signs of abnormal uterine development
Post Date November, 16 2024
The uterus is an important part of the female body and plays an important role, but abnormalities also occur in the uterus, especially in the development of the uterus. We must roughly understand it.
Types of uterine developmental abnormalities
1. Primordial uterus: also known as trace uterus. This is because the development of the accessory renal ducts on both sides stops shortly after merging. This type of uterus is very small, only 1-3 centimeters long, and because there is no endometrium, there is no menstruation, often accompanied by no vagina.
2. Mediastinal uterus: The accessory renal ducts on both sides have fully converged, but the mediastinum has not degenerated. The appearance of the uterus is normal, and the uterine cavity is divided into two parts. If the mediastinum is not completely degraded, an incomplete mediastinal uterus is formed. If the mediastinum extends to the vagina, it can also form a vaginal mediastinum.
3. Congenital absence of uterus: the middle segment of the accessory mesonephric duct on both sides is not developed, and the uterus cannot be synthesized. Patients often have no vagina, but their ovaries develop normally and Secondary sex characteristic are not affected.
4. Bicornuate uterus: most of the end of the accessory mesonephric tube is fused, and the mediastinum degenerates, forming a single cervix and a single vagina. The bottom of the uterus is incomplete, and the shape of the uterus is bicorn, so it is called Bicornuate uterus or saddle uterus.
5. Double uterus: Double uterus, double cervix, double vagina. It is caused by the lack of convergence of the accessory renal ducts on both sides.
6. Unicornuate uterus: one side of the accessory mesonephric duct on both sides is fully developed, and the other side is not fully developed or passed. It can be a residual horn uterus, which means only the uterine cavity has no uterine opening.
7. Dysplasia of uterus: also known as Uterine hypoplasia. After the merger of the accessory mesonephric ducts on both sides, the development stops for a short period of time. The cervix is relatively long, with a smaller outer opening, and the uterus is normally smaller. There are often infertility, Hypomenorrhea or irregular menstruation.
Symptoms of abnormal uterine development
1. Menstrual abnormalities: Patients with congenital absence of uterus or primordial uterus have no menstruation. The patients with immature uterus have no menstruation. The patients with double uterus and Bicornuate uterus who have Hypomenorrhea, delayed menstruation, dysmenorrhea, irregular physiological days and other manifestations of menstruation may have excessive menstruation, and the duration of physiological days may be prolonged.
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: Pregnancy often leads to miscarriage, premature birth, or abnormal fetal position. Occasionally, spontaneous uterine rupture during pregnancy may occur. If the fallopian tube of the rudimentary horn uterus is unobstructed, the pregnant eggs can be implanted into the rudimentary horn uterus, but the Myometrium is underdeveloped and ruptured during pregnancy, with the same symptoms as Ectopic pregnancy.
