The expectation of every family is to pass on the family line, and pediatric genitourinary disorders are always on the sensitive nerves of parents. We find that many parents do not know enough about this disease, which leads to irreparable damage. Genitourinary disorders are most common in boys. Parents are most likely to find the problem of “small balls and small penis” in young boys. Under normal circumstances, at birth, there is a testicle in the left and right scrotum, and the size is symmetrical. If the scrotum is empty, it indicates that the child has a “cryptorchid” and does not descend into the scrotum for 6 months after birth, then there is little chance of descending in the future. If there is a bag in the scrotum or inguinal area that appears with crying and activity and disappears when it is quiet, it is often referred to as a “hernia” and can be treated surgically if it recurs, without any age limit. If the bag does not change and is not painful to the touch and shines brightly with a flashlight, it is often called “water egg” – “syringomyelia”, which may disappear on its own within one year of age, but the effusion The sphincter may disappear on its own within one year of age, but if the fluid is too large and affects the blood flow to the testicles, surgery is still needed. Our urology department currently uses small incision surgery (incision of about 1cm), which is less invasive and faster healing, and is very popular with parents. Parents must pay enough attention to the redness and pain of the scrotum in young boys and must visit a specialized hospital to avoid testicular torsion and necrosis and regret. Most children have prepuce after birth, that is, the glans and urethral opening cannot be fully revealed, but after the age of 3, the prepuce adhesions have the possibility of natural separation and can be exposed, otherwise, it will often cause infections of the prepuce and glans, which can be operated after the age of 3. Here to remind parents that there is a special “prepuce” called “occult penis”, that is, the penis appearance is particularly short, only when urination is large, especially some obese children, is not suitable for simple circumcision. If you find that your child’s “penis” has an abnormal appearance: the penis body curves down, the urethral opening is not in the glans, the foreskin is unevenly distributed, or worse, the scrotum is split or the position of the “penis” and scrotum is reversed, that is “urethral Hypospadias”, which has been increasing in recent years, requires surgery at the age of 1 to 3 years. In addition, there are some children who have blurred genitalia and cannot be seen as male or female, which is a gender dysphoria and requires detailed examination at the hospital to determine the gender. With the popularity of prenatal ultrasound, it is possible to detect diseases of the upper urinary tract that doctors and parents cannot detect with the naked eye. For example, congenital hydronephrosis, ureteral dilatation, ureteral cyst, duplicated kidney, bladder malformation, and urological tumors, etc. After birth, a visit to the pediatric urology department is required to develop the next step of treatment. Common in little girls are, labia minora adhesions, hymenal atresia, and for girls who often wet their pants, attention should be paid to the presence of diseases such as ectopic ureteral openings and renal dysplasia. In short, the diagnosis and treatment of urological diseases in children is directly related to the well-being of the child’s life. The best age for surgery differs for different diseases, so parents should trust science and the strength of urology – “Only the professional, is the best!
