Many men delay treatment because they don't know what hypospadias is. Hypospadias may cause male penis to bend, affect male sexual function, and even lead to male reproductive difficulties. Then let's listen to the introduction of andrology experts in Shenzhen Hospital. Hypospadias is a congenital malformation of penis development, which is caused by the defects of corpus cavernosum and anterior urethra to varying degrees. Hypospadias refers to the fact that the external urethral orifice does not open at the top of glans penis, which is one of the most common congenital malformations of male reproductive system. About every 300~600 boys born, one child suffers from hypospadias. There are several treatments for hypospadias: 1. The penis bends without hypospadias: Generally speaking, it is recommended not to cut off the urethra, carefully remove the fibrous tissue around the urethra, and transfer the foreskin on the back of the penis to the ventral side to cover the urethra. If this method can't straighten the penis, cut off the urethra to straighten the penis, and perform urethroplasty on the urethra with intermediate defect. 2. Hypospadias with hypospadias: Hypospadias with hypospadias, and the degree of tissue defect around urethra is mostly Grade I. Therefore, it is generally required to cut the penis fascia to the outside of the tunica albuginea, so as not to hurt the tunica albuginea, completely remove the cord-like fibrous tissue on the outside of the tunica albuginea, and at the same time free the urethral orifice, remove the fibrous tissue attached to the penis around the urethral orifice, so that the urethral orifice moves backward, thus straightening the penis. Some scholars believe that the skin around the fibrous cord is often inelastic, which affects the penis and affects the straightening of the penis. It is emphasized that these skins should be removed and the defective skin can be covered with foreskin. 3. Penile deformity correction and urethroplasty can be completed at one time, mostly for penile hypospadias. The urethra is mostly foreskin-like. The foreskin has the advantages of thin skin, elasticity, hairlessness, short distance and good blood supply, so the formed urethra is not necrotic and the success rate is high. Others choose bladder mucosa strip to form urethra. The advantage is that it conforms to urethral physiology, but the disadvantage is that once it fails, the whole urethral necrosis can not be compensated. No matter what tissue is used to form urethra, the advantage of one-stage operation is that it can be completed at one time, with little pain and short course of treatment. Why men have hypospadias may be influenced by genetic factors. Senior andrologists said that if the male genetic factor SRY gene and related genes are missing or mutated, fetal urethral fusion will be interrupted, leading to hypospadias; The incidence of hypospadias in chromosome abnormal population is slightly higher than that in normal population. & gt& gt& gt Related reading: What are the hazards of bent stems? The main purpose of hypospadias operation is to urinate in a standing position, correct the deformity of penis curvature and make the external genitalia beautiful. Because of the different types of hypospadias, each patient's penis curvature, local penis skin and external urethral orifice are different, so it is necessary to make the best surgical plan suitable for him according to different patients' conditions. Warm reminder: don't panic when there is no cleft palate. Go to the hospital for examination and treatment in time so as not to affect your reproductive health.
