Uterine prolapse is a condition in which the uterus descends from its normal position along the vagina and the external cervical opening reaches below the level of the sciatic spine, or even the uterus is completely prolapsed outside the vaginal opening, often in combination with a bulging anterior and/or posterior vaginal wall. The anterior and posterior walls of the vagina are adjacent to the bladder and rectum, so uterine prolapse can be accompanied by vesicourethral and rectal bulging. Uterine prolapse is related to the relaxation of the ligaments supporting the uterus and the weakening of the pelvic floor support, so it is mostly seen in women with multiple births, poor nutrition and physical labor, with an incidence of 1% to 4%. 1, etiology 1, childbirth injury is the main reason for the onset of uterine prolapse. Childbirth, especially obstructed labor, prolonged second stage of labor or vaginal surgery assisted delivery, easy to cause damage to the cervix, main ligament of the cervix, uterosacral ligament and pelvic floor muscles, if the supporting tissues do not return to normal after delivery, uterine prolapse is likely to occur. 2, abdominal pressure increase chronic constipation and cough, ascites or abdominal obesity, can make the abdominal pressure increase, prompting uterine prolapse. 3, congenital developmental abnormality Uterine prolapse occurs in the unborn woman, due to poor development of reproductive organ support tissue. 4, malnutrition serious lack of nutrition can lead to muscle atrophy, pelvic fascia relaxation, the loss of support for the uterus. The prolapse of the uterus caused by malnutrition is often accompanied by symptoms such as gastric prolapse and abdominal wall relaxation. 5.Aging The decrease in estrogen secretion due to ovarian hypofunction makes the pelvic floor support tissues weak and flaccid, which makes uterine prolapse easy to occur or aggravates the original degree of prolapse. Clinical manifestations Patients feel that their abdomen is dropping, and it is more obvious when they are sore, walking and squatting. In mild prolapse, the prolapsed object in the vagina can be returned by itself after lying down and resting, but in severe cases, the prolapsed object cannot be returned and affects the movement. The mucosal surface of the cervix becomes thickened and keratinized or becomes eroded or ulcerated due to prolonged exposure. The leukorrhea increases and sometimes becomes purulent or bloody, and some patients experience menstrual disorders and excessive menstrual bleeding. When accompanied with bladder bulge, difficulty in urination, urinary retention, stress incontinence, etc. may occur. III. Diagnosis Diagnosis can be made based on symptoms, signs and pelvic examination. Uterine prolapse is the downward displacement of the uterus along the vagina, which can be divided into 3 degrees according to the degree of prolapse: 1. This degree of uterine prolapse does not require treatment and can be recovered by paying attention to rest. 2.Degree II The cervix has prolapsed outside the vaginal opening, while the uterine body or part of the uterine body is still inside the vagina. Grade II uterine prolapse is divided into two types: Grade II light The cervix is prolapsed outside the vaginal opening, but the uterine body is still inside the vagina. Grade II heavy The cervix, part of the uterine body and most or all of the anterior vaginal wall are prolapsed outside the vaginal opening. Grade III The entire uterine body and cervix are prolapsed out of the vaginal opening. Because of the effect of the operation on vaginal delivery again, the operation is only suitable for severe cases and women who are not going to have children. 1.Uterine support treatment (1) Indications Uterine support has been used to treat uterine prolapse for a long time. It enables the patient to master it by herself, but it is not suitable for those with severe uterine prolapse and excessive vaginal relaxation. (2) Model of uterine support It is appropriate to use a uterine support slightly larger than the genital (pubococcygeus caudalis) fissure, generally the fissure has a transverse diameter of 4 cm at most, so a medium size uterine support is mostly used. After a period of time, the pubococcygeus caudalis muscle gradually restores its elasticity, the tissue edema disappears after the reset of the prolapsed part, the weight is reduced, and the uterus can no longer be prolapsed. (3) Use time Generally put the brace in the morning before labor, take it out in the evening and wash it. It is best not to use during menstruation. The surface of the plastic tray is smooth, and it is not easy to deteriorate in the presence of acid and alkali, and it is less irritating to the tissues. After the rest, the symptoms will disappear and you can participate in all kinds of labor without pain. 2.Pelvic floor muscle exercise (kegel exercise) Suitable for patients with mild disease. The kegel exercise is: do the action of tightening the anus vagina by force, tighten for not less than 3 seconds each time and then relax, do it continuously for 15-30 minutes, perform it 2-3 times a day, or do it 150-200 times a day. The first exercise should be performed before waking up, 6-8 weeks for a course of treatment, 4-6 weeks patients have improvement, 3 months obvious effect. 3.Surgical treatment According to the etiology of uterine prolapse, the severity of the condition, the presence or absence of other surrounding organs bulging, the presence or absence of fertility requirements and other aspects of conditions, choose the appropriate surgical methods to achieve the purpose of restoring normal anatomy and its function. This includes shortening the lax primary ligament to improve the supporting force of the uterus; correcting abnormal uterine morphology, such as the cervix has been extended and hypertrophied, part of the cervix must be removed to restore the normal length of the cervix; shortening the pubic bladder cervical fascia to strengthen the supporting force of the anterior vaginal wall; suturing the pubococcygeal muscle fissure to re-establish a well-functioning perineal body. 4. Precautions (1) Take proper rest and avoid heavy physical labor. (2) Avoid prolonged standing or squatting, breath-holding and other actions that increase abdominal pressure. (3) Keep urine and stool open. (4) timely treatment of chronic bronchitis and other diseases that increase abdominal pressure. (5) Appropriate physical exercise to improve physical fitness.
