Introduction

Introduction The primordial uterus is also called the uterus. During the fetal development period, the female reproductive organs are converged from the bilateral renal tube in both sides. The primordial uterus is stopped shortly after the confluence of the renal tube on both sides, often without vagina. This uterus is very small, only 1 to 3 cm long, no uterine cavity, no endometrium, no menstrual cramps. Vaginal four-dimensional color Doppler ultrasound, you can clearly see the image of the primordial uterus, the initial uterus is very small, like a cord-like, no uterine wave. Since the primordial uterus has no uterine cavity, no endometrium, there will be no menstrual cramps.

Cause

Cause

During the fetal development period, the female reproductive organs are converged from the bilateral middle and middle kidney tubes, and the development of the basal uterus on both sides of the collaterals is stopped shortly after confluence.

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

Diagnosis

Differential diagnosis

Differential diagnosis of the primordial uterus:

1. Congenital absence of uterus: the bilateral renal tube on both sides extends to meet 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.

2. 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.
