There are many classification systems for congenital utero vaginal anomalies. These include
- Buttram and Gibbons classification 2
- American Fertility Society (AFS) classification
- modified Rock and Adam - AFS classification
Modified Rock and Adam - AFS classification
This classification divides congenital uterine anomalies into 4 main types which include
class I : dysgenesis of
- includes agenesis or hypoplasia of the müllerian duct derivatives: the uterus and upper two-thirds of the vagina
- the most common form is the Mayer-Rokitansky-Kuster-Hauser syndrome - is combined agenesis of the uterus, cervix, and upper portion of the vagina.
class II : disorders of vertical fusion.
- these anomalies are due to failure of fusion of the müllerian system with the sinovaginal bulb.
- they include cervical dysgenesis and obstructive and nonobstructive transverse vaginal septa
class III : disorders of lateral
- describes anomalies that result in a duplicated or partially duplicated reproductive tract.
- these disorders are due to impaired fusion and / or septal resorption of fusing Müllerian ducts attempting to form the uterus, cervix, and upper vagina.
- it includes anomalies due to failure of fusion of the paired müllerian ducts (as in didelphic and bicornuate uteri) and failure of midline septum resorption after fusion (as in septate uterus).
- disorders due to
fusion defects are further subclassified into
- a : symmetric non-obstructive forms seen in five types: unicornuate, bicornuate, didelphic, septate, and DES-related uteri and
- b : asymmetric obstructive forms seen in three types: unicornuate uterus with obstructed horn, double uterus with unilaterally obstructed horn, and double uterus with unilaterally obstructed vagina.
- class IV : unusual configurations and combinations of defects
