vaginal cyst
Introduction
Introduction to vaginal cysts Vaginal cysts are the most common vaginal benign tumors. There are no glands in the normal vagina, but occasionally isolated vaginal crypts can be found, and thus a fluid-containing retention cyst is formed, which is not a neoplastic or proliferative tumor. Vaginal cysts are divided into epithelial inclusion cysts (acquired) and embryonic residual cysts (congenital). Generally, the cyst epithelium is mostly derived from the embryonic stage of the Mullerian tube, the middle kidney tube and the genitourinary sinus. basic knowledge The proportion of illness: 0.001% Susceptible people: women Mode of infection: non-infectious Complications: vaginitis urinary infection
Cause
Cause of vaginal cyst
The epithelial inclusion cyst is due to damage to the vaginal mucosa during childbirth, or the vaginal mucosa is entangled deep into the vagina when vaginal surgery is performed. After the wound heals, the mucosa continues to proliferate and desquamate, and then liquefies to form a cyst. Pathological examinations are mostly stratified flat cells. Generally asymptomatic, often found at the time of examination. Embryonic residual cysts are also called middle renal cysts. If there is obstruction in the middle kidney tube next to the vagina, the secretions can form cysts, which can be seen in the anterior wall of the vaginal side wall or the lower part, in a string or multiple, such as grapes or ping pong. The size of the ball, the wall of the cyst is thin as a single room.
Prevention
Vaginal cyst prevention
According to the cause, in addition to avoiding vaginal damage, regular gynaecological examinations are advocated, and early treatment is early detection.
Complication
Vaginal cyst complications Complications vaginitis urinary infection
Symptoms such as urinary tract infection.
Symptom
Symptoms of vaginal cysts Common symptoms Cysts, polyuria, urination, pain, labia, hypertrophy
Cysts may be segmented or majority, cysts vary in size, generally 2 to 3 cm in diameter, smooth in appearance, fixed, and have a sac. Such cysts are often small and have no clinical significance, but occasionally they can grow very large, causing difficulty in sexual intercourse or painful intercourse, and even hinder delivery, sometimes compressing the trigone of the bladder, causing an increase in the number of urination. In very few cases, the slender cord-like pedicle can cause distortion and obstruction of the intestine.
The contents of the cyst are mostly watery, serous or milky white, and also dark brown. Its color and viscosity vary depending on the presence or absence of intracapsular hemorrhage and the amount of bleeding.
Examine
Examination of vaginal cysts
1. Mainly by asking the patient's medical history to understand the progress of his cyst.
2. Gynecological examination, preliminary assessment of cyst location and adjacent anatomy.
3. Imaging examination: B-ultrasound, MRI examination, etc., to further clarify the size, location and content of the patient's cyst.
Diagnosis
Diagnosis and differentiation of vaginal cysts
A small cyst located on the anterior and lateral wall of the vagina has no difficulty in diagnosis.
Large and sudden in the vaginal or labia, although the shape of the bladder bulging, but after urination, it is not reduced, or after the insertion of a metal catheter, while pinching the base of the cyst with a finger, feeling the catheter and cyst A certain distance, it is not difficult to identify.
The cyst located in the posterior vagina of the vagina should be differentiated from the uterus rectal fossa. The latter increases each time it coughs, or shrinks or even disappears when pushed up with a finger. In the triad, the patient uses abdominal pressure and may have a vaginal rectum. The feeling of bulging, bulging, this is caused by the abdominal pressure of the intestines into the vaginal rectal fossa, while the vaginal cysts have no such changes.
The cyst located in the lower part of the anterior vaginal wall must be differentiated from the urethral diverticulum and the urethral gland abscess. Although the latter two also form vaginal bulging, they are all connected with the urethra. When the hand is pressed forward, urine or pus can be seen from the urethra.
The small cyst located near the female membrane of the posterior wall of the vagina is mostly a cyst. In addition, it must be differentiated from double uterus, double vaginal malformation, and one side vaginal atresia. This situation is extremely rare. Although the patient has menstruation, the dysmenorrhea gradually worsens, and the formed vaginal side cyst has a large tension and color purple. Local puncture identification is possible if necessary.
