The vagina is a muscular canal composed of mucous membrane, muscular layer and outer membrane, which is very stretchable and is a very important canal connecting the female internal and external genitalia. It is an organ of sexual intercourse and a channel for the discharge of menstrual blood and the delivery of the fetus. The upper part of the vagina is connected to the uterus and the lower part opens into the vestibule with the vaginal opening. The front of the vagina is adjacent to the bladder and urethra, while the back is connected to the rectum and perineum. The normal vagina is 2.5 cm in diameter and about 8 cm in length, and is surrounded by many muscles and ligaments that keep it in tension. There are many folds in the mucosa of the vaginal lining. In vaginal laxity, the muscles are weakened, the ligaments are relaxed and the mucosal folds are reduced, which directly affects the harmony of sexual life. The laxity of the vagina can be caused by excessive childbirth, birth injuries and surgery. In the past, due to the traditional feudal concept, it was often taboo to seek treatment for this problem. With the improvement of people’s living standard and civilization, more and more families are paying more attention to the quality of married life, and more and more women are coming to hospitals to correct vaginal laxity. Vaginal tightening can be considered for those who have unsatisfactory sex life due to vaginal laxity after vaginal delivery, old perineal tears, poor wound healing after lateral perineal incision or congenital reasons. Before the surgery, in addition to the usual blood tests to check the general condition of the body, gynecological examinations are usually required to rule out vaginal inflammation, cervical lesions, anterior vaginal wall bulge, and pregnancy as unsuitable conditions for surgery. The procedure is usually scheduled 3-7 days after the menstrual period. Starting 3 days before the procedure, the vulva should be washed with 0.1% Neosporin daily to keep it dry and clean, and sexual intercourse should be prohibited. The procedure can be performed under local anesthesia and can be completed in about half an hour. The position is taken in the bladder truncated position and the posterior vaginal wall is anesthetized by the swelling technique. A curved incision is made on the skin side of the posterior vaginal wall at the junction of the skin and mucosa and 1/2 of the full length of the posterior vaginal wall mucosa is peeled away under the vaginal mucosa and the muscular tissues of both walls are pulled together and sutured. The vaginal mucosa is not removed if it is convex to the vagina, and the integrity of the mucosal layer is maintained. If the wound heals poorly after lateral incision, it can be repaired together. The advantage of this procedure is that it reduces the volume of the vagina while creating a new vaginal fold and maintains the extension of the vagina. The vagina needs to be filled with oiled gauze rolls to stop the bleeding after the surgery. For the first 24 hours after surgery, it is advisable for the patient to remain in bed with minimal movement on the floor to avoid bleeding from the wound or even the formation of a hematoma. If conditions allow, it is safer to stay in the hospital for observation overnight. The stuffed gauze can usually be removed the next day. After surgery, antibiotics should be used appropriately, the wound should be kept clean and dry, and the stool should be kept open. The surgery is usually performed with absorbable threads, which do not need to be removed. If the absorbable thread is absorbed slowly and the thread causes discomfort in the area, you can come to the hospital to have the thread removed. To minimize the side effects of vaginal tightening, avoid strenuous activities for one week after surgery. Although all surgeries have certain risks and vaginal tightening surgery may have certain side effects, the repair is done according to the different ages of the patients and the different degrees of vaginal laxity and perineal damage. Through the surgery, the damaged and lax muscles and fascia are repaired, so that the vaginal elasticity is increased and the tightness becomes suitable, and the lacerated perineum is restored to its prenatal state after repair.
