General Information
Understanding the main stages of embryogenesis (see Section 3.2.2) gives an insight into the pathogenesis of malformations occurring in the genitals and urinary tract; this is important for differential diagnosis of gynecologic diseases and performing gynecologic and urologic surgery.
NB! Congenital malformation of genital organs is abnormality of its structure that lies outside the range of normal varieties.
Epidemiology
Female genital malformations account for 4-7% of all congenital malformations; malformations are seen in 3.2% of women of childbearing age. 6.5% of girls with gynecologic morbidity show vaginal and uterine malformations. Vaginal and uterine malformations are detected in every third infertile woman, and in every sixth patient presenting with miscarriage.
The close embryonic relation between the urinary and genital system underlies the combination of their malformations: the rate of combined urinary and genital malformations varies from 10 to 100%. The rate of genital malformations amounts
