Congenital absence of uterus

Introduction The renal tube on both sides of the kidney is extended to the midline and meets. If the development is stopped before the midline, no uterus is formed. Congenital absence of the uterus often combined with congenital absence of vagina, but can have normal fallopian tubes and ovaries. In the anus examination, it is equivalent to the cervix and uterus, and the uterus is not touched. Some patients with uterine malformations may have no symptoms, and menstruation, sexual life, pregnancy, childbirth, etc. are also abnormal, so that they are not found for life, or even found during physical examination. However, some patients' reproductive system functions are affected to varying degrees. When they are sexually mature, they are discovered after marriage, during pregnancy, or during childbirth. Uterine dysplasia, if not caused by clinical symptoms, may not need to be treated. If the uterine dysplasia causes amenorrhea, dysmenorrhea, infertility or habitual abortion, try endocrine therapy. Detailed treatment methods are detailed in the relevant chapters. Surgery may be considered for those who cannot relieve the patient's pain after drug treatment. For dysmenorrhea, surgical removal of the deformed uterus may also be considered. If the uterine malformation causes abortion and premature birth, the corresponding surgery can be taken according to different deformities.

Cause

Congenital uterine dysplasia is the most common type of genital malformation, and its clinical significance is relatively large. In the process of evolution, the bilateral middle and middle kidney tubes are affected and interfered by certain factors, and can stop developing at different stages of evolution to form various dysplastic uterus. Congenital absence of uterus on both sides of the middle and middle of the renal tube was not developed and reconciled, often combined with no vagina, but ovarian development is normal, secondary sexual characteristics are not affected. Rectal-abdominal examination does not reach the uterus.

Rectal-abdominal examination does not reach the uterus, B-ultrasound can be diagnosed.

The middle and the middle of the renal tube were not developed and reconciled on both sides, often without vagina, but the ovarian development was normal, and the second sexual characteristics were not affected. Rectal-abdominal examination does not reach the uterus.

Congenital absence of uterus is the bilateral renal tube in both sides extending transversely to meet the midline. If the development is stopped before the midline, no uterus is formed. Congenital absence of the uterus often combined with congenital absence of vagina, but can have normal fallopian tubes and ovaries. In the anus examination, it is equivalent to the cervix and uterus, and the uterus is not touched. Uterine dysplasia without uterus, primordial uterus, naive uterus, etc., is often one of the main causes of infertility.

There is no therapeutic basis for congenital uterus, naive uterus and no uterine cavity. For patients with impaired uterus due to endocrine disorders, taking the drug female gynecology, dredge and taking estrogen It usually cures and improves uterine development in about 3 months. Endometriosis should be taken with danazol, which can be cured for 2 to 3 months.

Differential diagnosis

The basal uterus: If the bilateral middle and middle kidney tubes extend to the midline and extend to the midline, the uterus is small. There is no uterine cavity or no uterine cavity and no intimal growth, so there is no menstrual cramps. Have a vagina.

Diagnosis: relying on electronic colposcopy, intracavitary four-dimensional color Doppler ultrasound, chromosome analysis and electrochemiluminescence endocrine testing can be diagnosed.

Naive uterus: At any stage during the third trimester of pregnancy or after the birth of the fetus to puberty, the uterus stops developing and various degrees of uterine hypoplasia can occur. The cervix of this type of uterus is relatively long, mostly conical, and the outer mouth is small; the uterus is smaller than normal, often showing extreme flexion or flexion. Forequarters often have dysplasia of the anterior wall of the uterus, and those with posterior flexion often have hypoplasia of the posterior wall of the uterus A naive uterus can cause dysmenorrhea, less menstruation, amenorrhea or infertility.

Diagnosis: relying on dynamic digital uterine fallopian tube angiography, intracavitary four-dimensional color Doppler ultrasound, chromosome analysis and electrochemiluminescence endocrine testing can be diagnosed.
