The most common problem we encounter in the clinic is circumcision, from a few months to a teenager, and the most common question parents ask is “Do I need surgery?” The treatment of prepuce includes both surgical and non-surgical treatments. Surgical treatment is generally familiar to everyone, that is, circumcision, I personally think that circumcision is now a bit overwhelming, after all, most people in the country do not have religious needs, “non-therapeutic routine circumcision” may bring physical or psychological harm to the child, we are generally in accordance with the indications for surgery for circumcision to do We generally follow the indications for circumcision, i.e. Practical Pediatric Urology: 1. fibrous stenosis ring at the foreskin opening; 2. recurrent episodes of penile head circumcision; 3. narrowing of the foreskin opening after the age of 5, where the foreskin cannot be retracted and the head of the penis is exposed, which needs to be mastered according to the specific situation of the child and the parents’ requirements. Regarding non-surgical treatment, the following are commonly used: 1. Foreskin mouth expansion method This method needs to be carried out in a hospital, but can be done on an outpatient basis in general. After disinfecting the external genitalia, a vascular forceps is inserted from the foreskin opening, and while inserting towards the coronal groove, the tip of the forceps is opened to separate the adhesions and dilate the foreskin opening, while the left hand assists in turning up the foreskin to the coronal groove to remove the foreskin wax. After the procedure, the foreskin needs to be turned up and cleaned frequently. The advantage of this method is that it is simple and quick, but the disadvantage is that it is more violent and the child is not easy to cooperate because of pain, and after the operation it is difficult for the parents to insist on upturning because of pain, and there is a possibility of re-adhesion. This method is better for foreskin mouth is not particularly narrow, only foreskin adhesions. Point: must insist on turning up, otherwise re-adhesion. 2, hand flip method doctors teach parents, can be done at home. It is best to cooperate with 2 people, one person palm hold the child, the other person gently push up the foreskin, exposing the urethra. This method can not be rushed, not to mention forcibly flip the foreskin, because too much force can tear the foreskin, need to be gradual. Sometimes parents can not persist for a long time and affect the effect. Point: step by step, do not rush. 3.Circumcision orthopedic expander treatment This method was introduced at the 8th National Pediatric Urology Symposium in 2011, and it works well after use. The product is made of the latest international materials, weighing only 0.3 grams, which can gently, continuously and fully expand and relax the foreskin opening, and is simple to operate and basically painless. For young children with a narrow foreskin opening, who do not need surgery for the time being, the treatment effect is more satisfactory.
