Hymen atresia

Introduction

Introduction to 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, which is in the shape of a half moon. Occasionally, there is a septum. The hymen hole is divided into two halves, which are called the septum or the two-hole hymen. There is also a membrane in the form of a sieve covering the vaginal opening, which is called a sieve-like hymen. If the hymen pleats are over-developed, it is a non-porous hymen, which is a hymen atresia, which is more common in female genital dysplasia. During the examination, the hymen can be seen to bulge and swell, and the membrane is purple-blue (menstrual blood retention). The lower abdomen can be touched with a large degree of tension and tenderness. Anal examination of the mass to the rectum, tension, and tenderness. In order to exclude other female reproductive system developmental abnormalities and other urinary dysplasia, gynecological ultrasound, pelvic magnetic resonance imaging and other imaging examinations are feasible. basic knowledge The proportion of illness: 0.052% Susceptible people: good for women Mode of infection: non-infectious Complications: constipation, urinary retention

Cause

Hymen atresia

Congenital malformation (40%):

Hymen atresia is not uncommon and is the simplest deformity of the female reproductive organs. It occurs because during the embryonic development, the genitourinary sinus that constitutes the hymen is not caused by vaginal perforation, and the internal genitalia (including the ovaries, fallopian tubes, uterus, and vagina) are often normal.

Hymen pleats develop vigorously (25%):

Due to the vigorous development of the hymen pleats, the urogenital sinus epithelium failed to penetrate the vestibular part. Hymen atresia is more common after menarche, such as normal uterus and vaginal development, blood accumulation in the vagina after menarche, and then extended to the uterus, forming vaginal uterine hemorrhage, excessive blood can flow into the fallopian tube, through the umbrella into the abdominal cavity, The peritoneum near the umbrella is stimulated by menstrual blood to cause edema and adhesion, which causes the umbrella of the fallopian tube to be locked, forming blood in the vagina, uterus and fallopian tubes.

Prevention

Hymen atresia prevention

For the hymen atresia, there are currently no clear methods and drugs for prevention. Early detection, the selection of appropriate surgical timing and surgical methods will help the patient's smooth recovery.

Complication

Hymen atresia complications Complications constipation urinary retention

Severe with constipation, frequent urination or urinary retention, constipation, anal bulge and other symptoms.

Symptom

Hymen atresia symptoms Common symptoms Hymen no pore tension vaginal transverse urinary frequency anal bulge congenital without vagina

1. There is no menarche after puberty.

2. Gradually worse abdominal pain.

3, the lower abdomen can touch the mass, and increase month by month.

4. When the examination is carried out, the hymen is bulging outward and the surface is purple-blue.

5, anal examination to the pressure of the rectum, tension, and tenderness of the mass.

6, severe with constipation, frequent urination or urinary retention, constipation, anal bulge and other symptoms.




Examine

Hymen atresia check

During the examination, the hymen can be seen to bulge and swell, and the membrane is purple-blue (menstrual blood retention). The lower abdomen can be touched with a large degree of tension and tenderness. Anal examination of the mass to the rectum, tension, and tenderness. In order to exclude other female reproductive system developmental abnormalities and other urinary dysplasia, gynecological ultrasound, pelvic magnetic resonance imaging and other imaging examinations are feasible.

Diagnosis

Hymen atresia diagnosis

diagnosis

1. It can usually be diagnosed according to the above symptoms and signs, no need for auxiliary examination.

2. Puncture through the hymen sulcus, can extract sticky dark brown or old blood.

Differential diagnosis

Need to identify with the lower part of the vagina:

1. Location:

You can find a well-developed hymen, a distance from the vestibule or a certain depth of the vagina.

2. Thickness:

Thicker than the hymen.

3. Check the body:

No exogenous blue-purple mass.
