The surgery is done through robotic instruments via minimally invasive incisions ( less than 2 cm) on the abdomen. The uterus and parametrium will be delivered through a small incision inside the vagina. The actual non pregnant uterus is not very big ( size of a pear - around 6.5 x 4 cm) so it doesn't need a very large incision. Hope this helps. Da Vinci has very good results compared to conventional surgery.Good luck!
