The kidneys are two bean-shaped organs found on the left and right sides of the body. They filter the blood in order to make urine, to release and retain water, and to remove waste and nitrogen (the excretory system). Each kidney accounts for 50% of a person's blood filtration. It is possible to survive with only one. Carcinoma, one form of tumor cancer, weakens blood filtration.
Acquisition
While most animals have kidneys, the kidney item can only be acquired by harvesting them from human pawns through the surgery bill. This bill requires ? of any type of medicine to perform. Success chance is dependent on a number of factors, including bed quality, room cleanliness, and doctor skill - specifically the doctor's Medical Surgery Success Chance.
Up to two kidneys can be taken from a healthy patient but any damage, infection, carcinoma or other issue affecting a kidney will prevent harvesting. If both kidneys are taken, the patient will die.
Removing a kidney from a guest or prisoner decreases faction goodwill by 20 points down to a max of -100, and creates a -5 mood to your pawns for 8 days due to "someone's organ harvested", stacking up to 5 times, with a 0.75x multipler. Surgery on your own people gives "colonist's organ harvested" which is statisically identical to the previous mood penalty, however both types of mood penalties stack. The original owner of the organ receives a -30 mood penalty for 8 days. Lastly if the pawn is killed by taking the organ, the members of the colony gets an additional a -6 for 5 days.
Pawns with the Bloodlust and Psychopath trait are not affected by the harvesting of other people.
Analysis
While kidneys can be harvested from prisoners, guests and your own colonists, generally it is preferable to harvest from prisoners that you don't intend to recruit or sell into slavery. Their faction is generally already hostile, their mood is not as important as a colonists and the significant loss in Blood Filtration is less important.
There are two primary reasons to harvest an organ - trade and transplantation.
