This is a photo taken during laparoscopy of a uterosacral nerve ablation. This controversial procedure involves burning ( either by laser or by a bipolar device as is shown here ) the ligaments that attach the uterus to the sacrum (part of the pelvic bone). In this photo a bipolar cautery device is grasping the right uterosacral ligament as it joins the uterus. If you look closely, you can see where the tissue is already starting to turn white just above and below the bipolar device. This technique is controversial because some medical studies show that it works well for treating "central" pain, that is, pain with deep intercourse and pain in the center of the pelvis. However, other studies show that it does not work that well. Still other studies show that it only works for a short period of time. Thus, more research is needed.
