Hypospadias in babies is a common congenital malformation of the genitourinary system in male infants. The main manifestations are ectopic opening of the urethra, hypospadias and abnormal distribution of the prepuce. Hypospadias is caused by the cessation of the back-to-front closure process of the longitudinal urogenital groove on the ventral side of the genitourinary nodes. Hypospadias in babies is characterized by the following features: abnormal opening of the urethra; curvature of the penis to the ventral side; abnormal distribution of the foreskin of the penis, with a normal dorsal foreskin and a lack of a ventral foreskin; a thick, fibrous band that extends from the tethered portion of the penis to the abnormal urethral opening; and hypospadias of the urethral spongiosum. Hypospadias in babies is categorized into four types based on the abnormal urethral opening: penile head type; penile type; scrotal type; and perineal type. Hypospadias does not grow back on its own and must be treated surgically. When a baby has a hypospadias, it is important to actively seek medical attention and treatment under the guidance of a medical professional.
