is a membrane located inside the muscles, skin, and
fat of the abdomen. The peritoneum encases most of the
internal organs within the abdomen. Prostate cancer
patients who are undergoing the laparoscopic prostatectomy
or the robotic prostatectomy will have surgery that
either goes through the peritoneum or around the peritoneum.
Prostate surgery that goes through the peritoneum is
called transperitoneal. Prostate cancer surgery that
goes around the peritoneum is called extraperitoneal.
