Uterine polyps are common gynecological diseases, in a broad sense, all masses attached to the uterine wall by elongated tips, including endometrial polyps, endometrial adenomyomatous polyps, malignant polyps and so on. Most of them are benign and may have no obvious clinical symptoms, or cause increased menstruation, abnormal leucorrhea, vaginal bleeding, uterine enlargement, pain, etc. Hysteroscopy reveals polyps of different sizes and lengths, which are a common intrauterine lesion in gynecology. Among them, endometrial polyps are the most common. Classification of uterine polyps Uterine polyps is a common gynecological disease, according to the different growth sites, divided into cervical polyps and endometrial polyps. 1, cervical polyp: is the cervical canal glands and interstitial glandular hyperplasia, and protruding to the cervical ectocervix formed. Endometrial polyp: consists of endometrium covered with a layer of cuboidal epithelium or low columnar epithelium. Causes of uterine polyps 1, endocrine disorders Estrogen promotes the development of the vagina, uterus, fallopian tubes and ovaries themselves, but the long-term stimulation of high levels of estrogen can cause the endometrium to overgrow and form polyps. 2, inflammatory stimulation The main cause is the long-term stimulation of chronic inflammation, such as childbirth, miscarriage, puerperal infection, surgical operation or mechanical stimulation, sexual intercourse damage to the uterus, resulting in local mucosal hyperplasia and other lesions in the cervical canal, followed by gradual protrusion to the cervical ectocervix and the gradual formation of polyps. 3, other causes such as hypertension, diabetes, obesity, endometrial hyperplasia, ageing, etc. Clinical manifestations of uterine polyps 1, leucorrhea abnormalities Patients can appear increased leucorrhea, blood and other phenomena. A few polyps that are larger and longer can come out of the cervical opening, causing a small amount of vaginal bleeding, or bleeding after sexual intercourse. If the polyp becomes ulcerated, infected or necrotic, it will produce bloody or purulent leucorrhea. 2.Abnormal bleeding from the uterus Some women may experience excessive menstruation, shortened or prolonged periods, dripping, bleeding after conjugal life, and irregular vaginal bleeding after menopause. 3, infertility and miscarriage If uterine polyps grow in the cervical canal, they may prevent sperm from entering the uterine cavity; if they grow in the uterine cavity, they may prevent the fertilized egg from being laid or affect the development of the embryo, resulting in infertility or miscarriage. What tests are needed once a uterine polyp is suspected? 1.Ultrasound examination Transvaginal ultrasound examination can clarify the location, number and size of polyps in the uterine cavity. 2.Gynecological examination When the cervix is exposed with a vaginal speculum, uterine polyps of different sizes and shapes can be seen. 3.Hysteroscopy Hysteroscopy allows direct observation of polyps in the uterine cavity and also allows biopsy of suspicious lesions under direct vision. 4.Pathological examination Although cancer is rare, the cancer rate of uterine polyps is 0.2%~0.4%, so after removal, pathological examination is needed.
