Male hypospadias diagnosis and treatment of

Hypospadias in males (male food) genitourinary system the most common congenital malformations, the incidence is 1/300.

Some people think that this disease is recessive genetic, if couples have a risk of hypospadias in children, the other will be born child to 10 percent chance of happening. Normally, when the embryo 7 weeks after urethral wall from the proximal urethra wrinkles gradually to Balanitis-fusion into a tube-shaped the urethra, the process depends on the embryonic gonads secrete of the male hormone, also depends on the embryonic urethral wall cupboards and wrinkles on the cold in the response. When the urethra wrinkle formation, tubular wall obstacles occur that cause hypospadias.

In addition, the urethral opening of mesenchymal tissue is not development, formed a fan of fiber cable, urethral strictures and extending and embedding Balanitis.

Therefore hypospadias in Anatomy on five fundamental characteristics: 1 no frenulum; 2 wrapper is concentrated in the dorsal sheath is "turban-shaped"; 3 Balanitis flat as shovel-like; 4 under, erectile penis when you; 5 urethral meatal location exception.

Typing on the urethral opening clinical position classification.

① Balanitis-or subcoronal: urethral opening in Crown ventral Central sulcus. This type of addition of urethral opening is narrow, normal sexual intercourse without affecting urination and functions can be no surgery. Foreign emphasized aesthetic (cosmetic) surgery, advocates will forward to the urethral strictures in the normal position. ② urethral meatal penis type: open from the penis, necessary surgical correction of the ventral. 3 penoscrotal hypospadias shedding-type: in the junction of the scrotum, penis penis severely bent.

④ urethral meatal scrotum type: located in the scrotum, in addition to the General characteristics of hypospadias, and scrotal hypoplasia, to varying degrees on crack, which sometimes no testicles.

⑤ urethral strictures of perineum type: located in the perineum, external genitalia of extremely poor, and serious short penis, scrotum under Qu on crack, form, such as female genital mutilation (female food), sometimes mistaken for the girl child. ① Voiding symptoms, mainly for the original line of thin, uniform flow range from free, wet underwear when urinating. ② penis eyebrow bending down significantly. Hypospadias rectification must be operative.

Surgical purposes: first, to correct the deformities Qu, removal of the penis ventral cellulose (cellulose), fully straighten the penis.

Second, urethral forming and make it as close as possible to the open position. Indications: in addition to subcoronal hypospadias for may not be operated on, the type must be neck surgery to correct. Operation method: statistically operation in more than 150.

According to the operation of the technical, the patient's age and developmental situation differently penis.

Generally speaking, in the treatment of childhood is complete, you can eliminate the effects of mental patients, but age as small as possible without cooperation, coupled with a small penis, operational difficulties, so the chances of operation failed. So some people advocate the staging operation, i.e. when first cut fiber cable, correction of deformities Qu, pending the development of the penis before urethroplasty ii period. Complications common complications have urethral fistula, narrow, open, such as wound infection, prevention of complications is the secret of success. Preoperative preparations, in fine, after careful care can reduce the occurrence of complications.
