先天性阴茎缺如被认为是由于胚胎第4周生殖结节不发育的结果。发生率约3～4万个新生儿中有1例。这种畸形虽然阴茎缺如,但阴囊正常且可触及阴囊内睾丸。尿道异位开口于直肠或会阴,多伴发其他泌尿生殖系或胃肠道畸形。如尿道口位于肛门外括约肌近端,则新生儿期病死率为36%;如尿道口位于括约肌远侧,则病死率仅13%。对阴茎缺如患儿的治疗原则是尽早做变性手术,切除睾丸,做女性外生殖器成形。既往需分期手术,本文报告1例新生儿一期手术,而术前不做膀胱造口及结肠造瘘。患儿染
Congenital absence of the penis is thought to result from undeveloped reproductive nodules at the fourth week of the embryo. The incidence of about 40,000 newborns in 1 case. Although this deformity penis absent, but the scrotum normal and can reach the scrotal testis. Ectopic urethra openings in the rectum or perineum, associated with other genitourinary or gastrointestinal malformations. If the urethra is located in the proximal anal sphincter, the neonatal mortality rate was 36%; if the urethra in the distal sphincter, the case fatality rate was only 13%. The principle of treatment of children with penile deficiency is as early as possible to do degeneration surgery, removal of the testis, female genital mutilation. Previously required staging surgery, this report 1 case of neonatal surgery, and do not make a preoperative bladder stoma and colostomy. Children infected
