urethral meatus
Introduction
Introduction to urethral meat Urethral meat emulsion is a common urinary tract disease in women, mainly manifested as a benign polypoid mass in the urethra. Also known as urethral granuloma or vascular polyps. Its occurrence may be related to chronic inflammation or chronic stimulation of the vulva, severe reduction of estrogen levels, local submucosal varices and urethral mucosal prolapse and other factors. basic knowledge The proportion of illness: 0.0006% Susceptible people: women Mode of infection: non-infectious Complications: genital itching
Cause
Cause of urinary tract meat
Insufficient estrogen (40%):
The cause of the disease has not been clearly elucidated. Because it occurs mostly in postmenopausal women, it is generally considered to be related to the decrease in estrogen levels. It has been reported that urinary prolapse caused by insufficient estrogen may be the first step in the evolution of urethral meat.
Chronic inflammatory irritation (35%):
Local chronic inflammatory stimuli may also cause urethral mucosal valgus, epithelial cell proliferation around the urethral orifice, inflammatory cell infiltration and varicose veins to form a meaty lesion, urethra meat may also be associated with trichomoniasis, tuberculosis, intestine Ectopic, urethral hymen fusion, but related research is rare, urethral meat mites are rare in premenopausal and adolescent women, but there have been reports of urinary tract mites in 2 year old girls, in addition, males at home and abroad Case report of urinary tract meat.
Pathogenesis:
The urethral meat sputum is usually small, but it can reach 1~2cm. It is more common at about 6 o'clock in the posterior lip of the urethra. Other parts of the urethra are rare. Very few can occur in the urethra. Most of the base is wide and some are pedicled. Microscopic observation of the urethral meat mites looks like a granulation tissue bed covered by squamous or transitional epithelium, showing a large number of expanded capillaries and fibers, the epithelial tissue wrapping can form a papillary structure, inflammatory infiltration is very common, according to Different degrees of inflammatory cell infiltration, fibrosis and varicose veins can be divided into three types: papilloma, hemangioma and granuloma.
Prevention
Urethral meat emulsion prevention
1, regular physical examination: to achieve early detection, early diagnosis, early treatment.
2, good follow-up: to prevent the disease from getting worse.
3, personal hygiene, keep the vulva clean, dry, often change underwear, wear cotton underwear, regular gynecological examination.
4, enhance physical fitness, improve their own immunity: pay attention to work and rest, participate in physical exercise, strengthen nutrition, intake of high protein, high carbohydrate, high calorie, high vitamin, low fat full nutrition diet.
Complication
Urethral meat fistula complications Complications, genital itching
1. Complicated with urinary tract infection, causing frequent urination, urgency, dysuria and other symptoms, usually diagnosed by clinical symptoms and regular urine examination.
2. Concurrent vulvovaginitis, resulting in increased local secretions, itching discomfort, burning sensation, etc., through the routine examination of leucorrhea, can be diagnosed.
3. The hyperplasia of the meat is large, and the friction of the clothes causes bleeding and secondary infection. Severe cases can lead to sexual life not working properly.
Symptom
Urethral meat licking symptoms Common symptoms Urethral pain urethra thickening Hard urinary tract burning urinary urinary genital sinus
1. Pain in the urethra: There may be burning pain, pain in urination, activities, clothing friction, and sexual intercourse during sexual intercourse, sometimes causing frequent urination and urination.
2. Contact bleeding: contact, easy to bleed after friction, but rarely a large amount of bleeding.
Examine
Examination of urethral meat emulsion
1. Physical examination showed dark red or bright red brittle tumor-like tissue on the posterior wall of the external urethra. The surface was smooth, soft and painful, and easy to bleed. Generally 0.5 ~ 1.0 cm, with pedicle or base is wider, and some ring around the urethra.
2. Pathological examination revealed dilated capillaries, connective tissue and epithelial cells.
Diagnosis
Diagnostic identification of urethral meat
diagnosis
The disease can be diagnosed based on clinical manifestations.
Differential diagnosis
The diagnosis of this disease is not difficult, such as the surface of the meat mites, infection, increased volume, easy to be confused with the following diseases.
Urethral polyps
For a benign tumor that occurs in the urethra, the polyp of the polyp is slender and can be removed from the urethra. It is bright red and connected to the deep urethra. The pathological examination is polypoid-like. The surface is a transitional epithelium containing fibrous vascular tissue.
2. Urethral mucosal prolapse
It is characterized by a purple-red mass in the urethra, which is annular around the urethra. The mass is soft, the surface is smooth, without pain or tenderness, and it is prone to hemorrhage. There is a cavity in the center of the mass, which can be smoothly inserted into the catheter.
3. Urethral cancer
It is characterized by a mass at the urethral opening, ulceration on the surface, and bloody or purulent secretions. It is hard to touch, irregular in shape, tender, may be associated with inguinal lymphadenopathy or distant metastasis, biopsy Can be clearly diagnosed.
4. Paraurethralitis
For the non-specific infection of the submucosal small glands of the urethra on both sides of the female urethra, a paraurethral cyst or abscess can be formed, which is characterized by swelling and pain in the urethra. The urethral orifice can touch the mass with tenderness and sometimes extrude. a substance or a limestone clot.
5. External urethra condyloma acuminata
It is characterized by single or multiple red cauliflower-like masses outside the urethra. The surface is uneven, there are erosions and exudates, and it is easy to bleed. It has similarities with urethral meat, but this disease is a sexually transmitted disease. A history of clean sexual intercourse, at the same time, similar lesions can be seen in the vagina, labia, anus, etc., and the pathological examination must be performed in the diagnosis.
