Hypospadias is a congenital malformation formed when the external urethral opening is not in the normal urethral position, mainly due to the underdevelopment of the anterior urethra, which is related to the hormone level in the patient’s body as well as genetics and the surrounding environment, and can develop in both men and women, mainly in men. According to the location of the urethral opening, it can be divided into four types, such as penile head type, penile type, scrotal type and perineal type. The penile head type urethral opening is usually located on the ventral side of the coronal groove of the glans, and the foreskin tether is usually missing and the foreskin is piled up together to form a cap-like foreskin. The penile type urethral opening is located at the junction of the ventral coronal sulcus and the penis. The penis is usually curved more significantly and the urine stream is spurting during urination. Scrotal type hypospadias is when the urethral opening is located in the scrotum, on the median line of the scrotum, and generally many patients with this condition will have cryptorchidism. The perineal type is when the urethral opening is located in the perineum, and usually the scrotum is usually underdeveloped in patients with this condition.
