Frequent urination in children is very common in outpatient clinics, mostly in preschool children, often presenting with intermittent symptoms of frequent urination, not accompanied by hematuria or pain. Especially in the period before children go to bed, once in a few minutes, the amount is very small, sometimes a few drops of urine or squatting for a while without urine discharge at all, and in the morning when they wake up they can discharge a large bubble of urine. In kindergarten or during school most of the time is able to hold a class, some children’s teachers will reflect to parents often pee pants, the amount is very small, manifested as a cloud of wet in front of the pants, not really pee pants. Sometimes parents do not pay special attention to the symptoms of the child and it gets better, or the child often scratches the “chick” with his hands. The urine test at the hospital shows occult blood and red blood cells and a small amount of white blood cells, and after oral anti-inflammatory drugs have improved, most of them come back or don’t work. Many hospitals are at their wits’ end, even treating it as neurogenic dysuria with poor results, which makes parents very nervous. In fact, this kind of disease is very common in our hospital, the hospital does not need to do a good job for the child more than one examination, only in the examination of the child’s “chicken” foreskin can not be turned up, there is one or several hard white or light yellow mass, activity, no pressure pain, this is the foreskin adhesion caused by the so-called mass is the foreskin scale, that is, the people usually say The so-called lumps are prepuce, or “urine rust” as the people usually call it, and it is the stimulus that causes the child to urinate frequently, and is not a serious illness. Many non-pediatric surgeons will tell you that poor hygiene requires you to flush your child’s foreskin upward often, which parents simply can’t do, not because they don’t know how to do it, but because the child’s lack of cooperation makes parents helpless. Some doctors may say that circumcision is needed, which makes parents even more worried, either criticizing their children or seeking medical help. Here I can say for sure that 99% of this disease does not need surgery, in the clinic to do a simple foreskin separation on the line, it takes a minute, a little pain, most do not bleed, occasionally swelling, not delay the child the next day to school or kindergarten, the only thing parents have to do is to follow the doctor’s instructions for the child to soak the affected area with medicinal water 1-3 days.
