Hypospadias is a congenital malformation of the male genitalia and is a congenital defect with an abnormal position of the urethral opening. The urethral opening can be distributed on the line from the normal urethral opening to the perineum, and most patients can have a ventral bending of the penis and urination in a squatting position. According to the location of the urethral opening, hypospadias is divided into penile head type, penile type, scrotal type and perineal type. The main reason for its formation is due to the fact that the penile fascia and skin fail to develop normally on the ventral side of the penis during the development of 8-14 weeks of pregnancy, and the urethral groove fuses incompletely and forms hypospadias, while the urethral corpus cavernosum also develops incompletely, forming a cord at the distal end of hypospadias, which can lead to penile curvature. It is currently considered to be related to single gene mutations, advanced maternal age, endocrine levels, ovulation-promoting drugs, anti-epileptic drugs, low birth weight babies, and pre-eclampsia. Patients with hypospadias often require multiple surgical procedures to heal due to the low success rate of surgical treatment, which needs to be started at the age of 2-3 years and completed before school age. Otherwise, it is easy to have a serious psychological impact on the patient. In summary, hypospadias is a congenital genital disorder with abnormal urethral opening in men, which is related to a variety of factors and requires early surgical treatment.
