The andrology expert of Yan 'an Sunshine Hospital pointed out that all male penises have foreskin, but the length of foreskin is different. Like other human organs, the foreskin is born in the uterus and grows on the penis from infancy to death, which is a normal physiological structure of men. The foreskin can protect the glans from trauma and insect bite and keep the glans smooth, delicate and sensitive. It is understood that phimosis refers to the adhesion of glans and foreskin, and the foreskin cannot be turned over. There are complete adhesion and partial adhesion of phimosis, and some phimosis are closely adhered and need surgical separation; Some phimosis are loosely adhered or partially adhered. Without inflammation, the foreskin can be turned up. If the adhesion gradually leaves the glans penis, the foreskin can turn to the coronal groove. For phimosis with narrow prepuce mouth, when manual foreskin turnover and foreskin expansion are ineffective, operation should be performed to separate adhesion and remove foreskin. European NT seamless prepuce plastic surgery is based on the physiological characteristics of each man, taking a transverse incision of prepuce, separating and removing the excessive prepuce layer by layer, and positioning and shaping the prepuce frenum. Using new plastic suture technology, the appearance is beautiful and seamless, and the postoperative sexual function is obviously improved. It is the most satisfactory surgical method for men to treat phimosis with redundant prepuce. Advantages 1: This technique can easily remove the redundant foreskin from the penis root like taking off the cuff, and sew the incision at the root without affecting the beauty of the front of the penis. With the natural growth of body hair after operation, the incision can be completely hidden. Advantages 2: high surgical safety, quick recovery, no complications, no impotence or male infertility, and no influence on male reproductive function. In addition, the foreskin is separated at the superficial fascia level, which does not damage the penis blood vessels and causes less bleeding. At the same time, it protects the penis nerve and does not affect the postoperative sexual life.
