Proper penile development is generally more beneficial for reconstructing the urethra. The international standard is generally two age groups: half to one and a half years old and three to four years old. These two time periods are better for children to comply. Foreign countries generally require the head of the penis to be 1.5 cm wide to begin surgery, and central hospitals can begin surgery at about 1.4 cm. Because of the ethnicity factor, a large percentage of foreign children can reach the 1.5cm head width requirement at about half an age, so it is appropriate for them to start surgery at about half an age. Due to the limitations of the development of the yellow race itself, most of the penis head width can only reach about 1.2cm around one and a half years old, so it is difficult for domestic children to reach the international standard of half a year old. Considering the habits of domestic parents with their children, generally around one and a half years old children can understand some parents’ requests, and combined with the care conditions, post-operative family health support and other factors, Prof. Shaoji Chen generally recommends starting surgery around one and a half years old. This can solve the problem before the child understands, can avoid causing too much psychological impact on the child, and the post-operative care is not too difficult. If the child can achieve a penile head width of 1.5 cm within one year of age, the operation can naturally be started earlier, but if not, it is recommended to wait for the penis to develop better before surgical treatment. Our group recommends that surgery can be considered when the penile head width reaches 1.2cm or more, and the better the development, the better the postoperative appearance. Therefore, children with good penile development can be treated surgically at around one year of age. For patients with heavy hypospadias who need staged surgery, it is also recommended that the first surgery be started at around one year of age, so as to allow more adequate time for the second stage surgery. Therefore, it is recommended to see a pediatric urologist around one year of age to evaluate the timing of surgery in relation to the child’s condition and the doctor’s situation.
