Too long prepuce means that the prepuce completely or semi-wraps the glans penis, so that the glans penis can't be completely exposed. There are two types, one is that the penis completely wraps the glans penis, and even after complete erection, the glans penis can't be exposed. This is called true excessive prepuce. The other is to turn upside down by hand, or the glans penis can be completely exposed after erection, which is called pseudoprepuce. Either way, if not treated in time, it will cause other complications. Shenzhen Heping professional doctor analyzed in detail: Too long foreskin is harmful to too long foreskin. Not only affect their physical and mental health. At the same time, because there are a lot of bacteria hidden in the skin scale, it can invade the woman's vagina during sexual intercourse and cause infection. The long-term stimulation of skin scale is also one of the factors that lead to the woman's cervical cancer. Therefore, experts from Shenzhen Peace Hospital suggest that male teenagers with long foreskin and phimosis should be surgically removed as soon as possible, so as not to cause the following hazards: 1) It hinders the development of penis and affects the harmony of sexual life: in adolescence, because the penis head is tightly wrapped by the foreskin, it cannot be stimulated by the outside world, and the development of the penis head is greatly constrained. Adults will affect their normal sexual life because the foreskin is too long or phimosis. Especially for men whose foreskin is too small, the foreskin can't be recovered when it turns up, and the foreskin is tightly stuck in the coronary sulcus, forming an embedded phimosis, which is not very painful. Affect daily work and life. 2) It is easy to cause urogenital inflammation: there are rich sebaceous glands and a large number of secretions in the foreskin, so that the secretions can not be discharged and accumulate into scales and parasitize many pathogenic bacteria. Bacteria invading the urethra can cause urinary tract infection, which can cause dermatitis, balanitis and urethritis, and also increase the infection rate of genital warts, herpes and other sexual diseases. 3), leading to impotence, premature ejaculation, male infertility and other diseases: because the glans mucosa is usually stimulated less, the nerve feeling of the glans mucosa is too sensitive, and the friction between the glans and the vagina is vented at the touch of sex life, resulting in sexual pain. It also reduces sperm motility and semen viscosity due to premature ejaculation, inflammation, impotence and non-ejaculation, resulting in infertility. 4), damage renal function, induce cancer: due to inflammation, urethral orifice or anterior urethral stricture affects urine metabolism, and the bacteria in the foreskin will infect the kidney, which will damage the function of the kidney for a long time. Studies have shown that echinococcosis is a carcinogen and one of the factors leading to penile cancer in men. According to the survey, 85%-95% of penile cancer patients are phimosis or redundant prepuce. 5), endangering women's reproductive health and disease rehabilitation: Men's skin scale (residual urine crystallization) is an important cause of female cervical cancer. Skin scale is full of all kinds of bacteria. After being brought into vagina during sexual life, it causes repeated infection of gynecological diseases of women, stimulates uterus and induces cervical cancer, which is an important cause of malignant transformation of women's cervix. "Recommended Technology": Korean-style high-frequency photo-ion painless loop resection is minimally invasive, painless and flawless. Shenzhen Peace Hospital has matured this international leading technology, which can ensure the perfection of the operation from the following aspects: 1. Photoion technology is accurate to micron. Using the full digital reproductive shaping high frequency ion system, computer technology is used to calculate the distribution of blood vessels in the penis, the elasticity of the corpus cavernosum and the prostration of the penis, calculate the length of the penis after erection, and accurately calculate the cutting range of the inner and outer skin to microns. 2. The circumcision of the embroidered foreskin is natural and beautiful. Under the principle of safety, with natural beauty and coordination as the standard, avoid capillary carving. Circumcision, less bleeding during operation, no scar after operation, neat appearance, natural and beautiful. 3, Korean embroidery stitching technique wound smooth and natural. Compared with ordinary Korean prepuce surgery in the past, it is the first time to innovate the suture method of continuous suture or intermittent internal embroidery, which makes the wound heal flat and beautiful and does not affect the postoperative sexual life. This is a highlight of this technology's upgrade to the previous Korean technology. 4. Self-absorbing sterile suture is preferred. Breaking the traditional treatment method, we took the lead in adopting the self-absorption sterile suture, which was processed by a special process and absorbed by the human body after the wound healed, greatly accelerating the healing speed, recovering ahead of time and leaving no scars.
