Common Questions: The Procedure
Why is there less bleeding with laparoscopic radical prostatectomy?
The reduction in blood loss reflects the improved view of the operative field, especially behind the pubic bone, home of the venous plexus of Santorini. The improvement in view comes from using a lens that tracks directly into the operative field where the remote human eye has a hard time going. The laparoscopic radical prostatectomy provides also magnification and bright illumination. Overall, this improved view permits a more precise and gentle dissection, which means better control of potential sources of bleeding. Furthermore, the CO2 pressure probably compresses some of the smaller veins, which themselves are low-pressure systems.
