泌尿生殖系先天畸形较多,且在其它系统先天畸形中亦有30％以上并发泌尿生殖系畸形。男性泌尿系与生殖系更有其特殊联系,故二者先天畸形发病率高是可以理解的。以往,此类疾病多限于组织胚胎学阐述。随医学遗传学,特别是细胞遗传学的研究发展,六十年代以来,学者已普遍肯定遗传因素与先天畸形有密切关系。基此,以及优生学的要求,泌尿外科工作者有责任率先对有关知识进行再认识。再学习。我 Urogenital congenital malformations more, and in other systems, congenital malformations also have more than 30% and genitourinary deformity. Male urinary and reproductive system more of its special link, so both the high incidence of congenital malformations are understandable. In the past, such diseases were mostly confined to histological embryology. With the development of medical genetics, especially cytogenetics, since the 1960s, scholars have universally affirmed that genetic factors are closely related to congenital malformations. Based on this, and eugenics requirements, urological workers have the responsibility to take the lead in the knowledge of the re-understanding. study again. I
