title: Obstructed uteri with a cervix and vagina.
abstract: OBJECTIVE
  To describe a rare anomaly of the female reproductive tract and review the embryology associated with the defect.
  
  
  METHODS
  Case report and review of the literature.
  
  
  METHODS
  Major academic medical center.
  
  
  METHODS
  A 14-year-old girl with two hemiuteri lacking any communication with a single normal midline cervix and vagina.
  
  
  METHODS
  Diagnostic laparoscopy with chromopertubation to identify the anomaly and subsequent bilateral supracervical hemihysterectomies.
  
  
  METHODS
  Incidence, pathogenesis, fertility implications, and treatment options for patients with congenital defects in the upper vagina, cervix, and uterus.
  
  
  RESULTS
  Based on classic embryology, the lower vagina forms from the urogenital sinus while the upper vagina, cervix, and uterus form from the müllerian ducts. If a cervix is present, then the upper vagina and uterus are also usually present and should communicate.
  
  
  CONCLUSIONS
  This anomaly cannot be fully explained by traditional embryologic developmental theory. It is likely that an insult occurred between 9 weeks, when the uterovaginal canal is formed, and 12 weeks, when the müllerian ducts fuse.
