During the summer vacation, the Department of Urology is considered one of the busiest departments in the hospital, two months of summer vacation, an average of nearly 10,000 outpatient visits per month, almost twice as many as usual, the operating room is also fully booked, doctors are often busy until 1 a.m. to get off work. Usually children are busy with their studies, so parents choose to take their children to see a doctor at a later date, but there are some problems in urology that can wait, and some problems that can be regretted for life if delayed. I. The best time to treat cryptorchidism is within two years old Xiaoming’s parents are both doctors, and when he was one year old, his parents found that one of his testicles was cryptorchid. Cryptorchidism means that the testicle is not in the scrotum, but has made its home in the stomach. However, the parents thought that since the child was so small, the testicle would not be useful for the time being, so they would have to suffer a little bit to treat it, so they could wait until they grew up. After a careful examination, the doctor told them the unfortunate news that the testicle had been in the abdominal cavity for too long and was useless. Cryptorchidism, also known as incomplete testicular descent, is a common pediatric disease. Among newborns, about 4-10% of male babies are born with testicles that have not completely descended into the scrotum, but will continue to descend, and by the age of 1, the incidence of cryptorchidism is only 1 to 2%. If the testicle is still cryptorchid at this time, it needs to be surgically treated and reset. The best time for cryptorchidism surgery is within two years old. If not treated in time, cryptorchidism will not be able to produce sperm normally, which will affect the future fertility of the affected child, and the testicles of cryptorchidism are also prone to malignant changes. The best time to treat testicular torsion is 4-6 hours. For Frank, his 12th birthday will be remembered for the rest of his life, because on this day, he lost one of his “balls”. One day, he felt some swelling and pain in his balls, but out of shyness, he didn’t dare to tell his teacher, but chose to endure the pain in silence, until the fourth day, when he couldn’t stand the pain anymore, he told his teacher, who took him to Zhejiang Medical College for Children. After examination, the doctor found that one of his testicles had twisted, and because the twisting time had been as long as four days, the testicle was ischemic and necrotic for a long time, and could only be surgically removed, on this day, which happened to be his 12th birthday. The majority of testicular torsions start acutely, the cause of which is still unknown and occurs mostly in adolescents. Once testicular torsion is suspected, treatment needs to be a race to the bottom because in more than 4-6 hours, the testicle may become necrotic due to ischemia. The importance of the testicle to a man cannot be overstated. If one testicle is removed, it can cause a serious emotional burden to the child and his parents, and of course, it can have an impact on the child’s growth, development and fertility. However, if this happens to older boys, they may be reluctant to tell their parents or teachers because they are shy, choosing to endure it on their own in silence, holding back until they really can’t, but by then it may well be too late. On the one hand, parents should give their children some health education, but also learn to observe certain abnormal manifestations of their children, such as when they see their children walking with pouting buttocks, is to think if this is a problem in this area, ask your child in time to confirm the diagnosis early and avoid the loss of testicles.
