The differential diagnosis of congenital absence of vagina should be paid attention to

Many women do not know their own physiological structure, and do not pay much attention to the lack of menstruation during adolescence. They often find out that they have congenital absence of vagina on their wedding night. Congenital absence of vagina directly harms human health, and infertility is even more certain. Experts point out that the principle of treating congenital absence of vagina is to reconstruct the vagina. There are many methods of artificial vaginal formation, including non-surgical treatment, which is to use the means of top pressure to gradually push the closed vestibule mucosa in the normal vaginal position toward the head side along the vaginal axis to form an artificial cavity. This method requires a long treatment time, and the artificial vagina formed is short. So, what is the differential diagnosis of congenital absence of vagina? Let the experts introduce it in detail below.

1. Hymen atresia: The shape, size and thickness of the hymen hole vary from person to person. Generally, the hymen hole is located in the center and is half-moon-shaped. Occasionally, a septum appears, dividing the hymen hole into two halves, called a septum hymen or a double-hole hymen. There are also membranes that are sieve-shaped and cover the vaginal opening, called sieve-shaped hymens. If the hymen folds are overdeveloped and become a hymen without holes, it is hymen atresia, which is the most common abnormal development of female reproductive organs. It can be diagnosed based on symptoms and signs.

2. Primary amenorrhea: refers to women who are over 18 years old or whose secondary sexual characteristics have matured for more than 2 years but still have no menstruation. It is seen in congenital reproductive tract development abnormalities such as uterine hypoplasia or absence, congenital ovarian hypoplasia or absence, primary pituitary hypogonadism and congenital adrenal hyperplasia. In a few cases, pseudo-amenorrhea caused by lower reproductive tract atresia should be excluded.

Girls who have not had menstruation by the age of 18 should go to the hospital for examination. The cause of amenorrhea should be determined as much as possible based on medical history, comprehensive physical examination, and necessary auxiliary examinations. Further treatment should be given according to different causes. For example, congenital uterine hypoplasia can be treated with oral administration of small doses of estrogen to promote development, and congenital developmental malformations (such as absence of vagina, vulvar malformation, and lower reproductive tract atresia) can be corrected surgically.
