Primary Outcome Measures:
  • Operation time [ Time Frame: Participants will be followed for the duration of hospital stay, an expexted average of 8 months ]
    The primary objective is the operation time for each preparation side and instrument needed from the beginning of the removal of the cornual structure of the uterus (uterine cornu) till the completely removal of the parametric tissue directly before removal of the corpus uteri from the cervix.
