Abnormal uterine development is an abnormal condition that poses serious harm to women, especially with many adverse reactions. We should pay attention to timely examination, especially in daily life, and actively prevent it.
Symptoms of uterine dysplasia
1. Dysmenorrhea and pain are mainly manifested as secondary and progressive dysmenorrhea. Pain often occurs in the lower abdomen and lumbosacral region, and can spread to the vagina, perineum, anus, or thighs. From 1 to 2 days before menstruation, it continues to disappear after menstruation, but with the deterioration of the Menstrual cycle, the degree of pain is disproportionate to the size of the furnace.
2. Menstrual disorder, mainly increased menstrual volume or prolonged menstrual period, may be related to endometrial hyperplasia or ovarian dysfunction.
3. Infertility, many patients with endometriosis have unobstructed fallopian tubes, adhesions between the fallopian tubes and surrounding tissues, limited peristalsis, and a few patients have nodular thickening of the fallopian tube wall. Due to reasons such as the possible blockage of the uterine cavity, retroverted fixation, and ovarian dysfunction, about 74% of them have a history of infertility.
4. Dyspareunia: the ectopic endometrium in the pelvis often forms nodular lesions in the uterine rectal fossa, and the cervical collision and uterine rise during sexual intercourse cause pain.
Types of uterine developmental abnormalities
1. 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.
2. 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.
3. Mediastinal uterus: The accessory renal ducts on both sides are closed, but the mediastinum is not degraded. The appearance of the uterus is normal, with two parts of the uterine septum. Incomplete degeneration of the mediastinum leads to the formation of an incomplete mediastinal uterus. When the mediastinum extends to the vagina, it can also form a vaginal mediastinum.
4. Dysplasia of uterus: also known as Uterine hypoplasia. It is due to the cessation of development within a short period of time after the confluence of the accessory renal ducts on both sides. The cervix is relatively long, with a small outer opening, and the uterus is smaller than normal. There are often infertility, Hypomenorrhea or irregular menstruation.
5. Bicornuate uterus: because the tail of the accessory mesonephric tube has largely fused, the mediastinum has degenerated, forming a single cervix and a single vagina, the bottom of the uterus does not meet completely, and the shape of the uterus is bicornical, so it is called Bicornuate uterus or saddle uterus.
