The most likely cause of frequent urination in boys is prepuce or circumcision, and should be examined at a hospital. Check the penis, check whether the foreskin opening is small, whether the foreskin can be smoothly turned over to reveal the glans, check whether there is white discharge on the glans, whether there is foreskin scale gathered in the coronal groove of the foreskin, and whether the foreskin is adherent to the glans. If these manifestations are present, this is a case of glans glans irritating the urethra resulting in frequent urination. It is recommended that the foreskin should be turned over and the foreskin and urethral discharge should be cleaned every day, and the symptoms will slowly ease, and it is generally not advocated to take antimicrobials.
