With the holidays approaching, parents are busy looking for various training courses for their children to enhance their interests and strengths. The enrollment of various training courses is going on in full swing. However, the urology department of our hospital has become one of the running points for parents, which makes people deeply puzzled. After understanding, it was found that with the development of modern medicine, medical information is more and more developed, the majority of parents have increased awareness of their children’s reproductive health, and have a certain awareness of the dangers of circumcision, many parents take advantage of the long holidays to deliberately arrange for their children to be circumcised in the hospital, so that it does not affect the study, but also have enough time to rest and recover. For this reason, every year during the winter and summer holidays, the urology department of our hospital will set off a wave of “circumcision”. The increase in parents’ awareness of reproductive health is certainly a good thing for children. At the same time, we also know that there are still many parents who do not know much about the indications for circumcision and the timing of the operation, which delays the best time for the child’s surgery and affects the development of the child’s reproductive organs to some extent. So, which children need to be circumcised? The commonly referred to “circumcision” is medically known as “circumcision”. Parents should pay attention to the fact that not all boys must be circumcised, but children with one of the following conditions are recommended to be circumcised: a. After the age of 3, the foreskin mouth narrow, the foreskin can not be turned up and reveal the head of the penis, that is, more than 3 years old children with pediatric circumcision. (Every boy is born with prepuce, medically called “physiological prepuce”, is normal, before the age of 3 years old, if there is no recurrent infection, can not be operated. With age, the penis body grows and the penis erects at night, the head of the penis will be naturally exposed around the age of 5). Second, before the age of 3 years old, children with prepuce, such as repeated infection (can be manifested as the foreskin mouth red, swollen, painful, itchy, the affected often scratch with their hands, or have frequent urination, painful urination), narrow and small foreskin mouth caused by urination difficulties, urination when the foreskin bulging blisters. The surgery is also needed for those who have prepuce accumulation under the foreskin (generally parents can see or feel the soy-sized prepuce under the foreskin). The head of the penis is repeatedly inflamed, making the foreskin mouth scar contracture, and the formation of the acquired prepuce children. Fourth, the foreskin is too long and narrow foreskin mouth, the foreskin is not easy to turn up, or no erection can be free of strong turn up, erection can not turn up after the person. (Such patients are the most dangerous, if the penis erects after turning up the foreskin, the foreskin mouth stuck in the coronal groove, can not turn back, the formation of foreskin embedded, resulting in extreme swelling of the foreskin, and even foreskin and penis head ischemic necrosis, once the foreskin embedded, go to the regular hospital urology department immediately to deal with.) After listening to the above introduction, I believe that the majority of parents have a more in-depth understanding of circumcision. In addition, adults with the following conditions are also recommended to do circumcision: a. The foreskin is too long and can not often flip, cleaning, or in the case of frequent cleaning of the inner plate of the foreskin and the head of the penis still have more foreskin scale, membranous material, odor. Or the foreskin is red, swollen and cracked after sexual intercourse. Second, married men, with prepuce, lover with cervicitis, celiac disease, vaginitis and other gynecological diseases for a long time or repeatedly recurring Third, patients with benign tumors of the foreskin. Fourth, circumcision and more acromegaly, laser excision of acromegaly after the trauma is too large, will cause extensive skin necrosis. Fifth, the foreskin is too long and premature ejaculation. Sixth, those who want to engage in special activities and cannot wash regularly, such as joining the army, adventure, etc. Seven, there is a typical circumcision, currently no obvious discomfort, in order to prevent the above situation, feasible preventive circumcision.
