Hypospadias is caused by hypospadias, an ectopic urethral orifice located on the pathway from the normal position proximal to the perineum, and is complicated by penile hypospadias in most children. Hypospadias is a common congenital malformation of the pediatric urinary system, and the cause is not well understood. Self-diagnostic points The urethral orifice of hypospadias can be located anywhere from the proximal end of the normal urethra to the urethra of the perineum. The penis is curved ventrally. The foreskin is piled up dorsally on the head of the penis in the form of a cap and the foreskin tether is absent. The most common of the concomitant deformities of hypospadias are inguinal hernia and incomplete testicular descent. Clinically, it is classified according to the location of the urethral opening: Type I: glans type or coronal groove type; Type II: penile type; Type III: penile scrotal type; Type IV: perineal type. The main manifestations are abnormal urination such as thin urine line and wetting of clothes and pants during urination. The penis is obviously inferiorly flexed deformity when erect. The treatment recommendation is that hypospadias must be surgically corrected. The purpose of surgery: First, to correct the inferior flexion deformity, it is necessary to remove the ventral fibrin of the penis and completely straighten the penis. Secondly, to shape the urethra and to position the opening as close to normal as possible. There are many surgical procedures and different procedures should be chosen according to the skill of the surgeon, the age of the patient and the development of the penis. Precautions Generally speaking, completing the treatment in preschool (2-5 years old) eliminates the psychological impact on the affected child.
