==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. It is also recommended to pick either colonist harvesting or prisoner/guest harvesting as they two debuffs stack and only the like debuffs have the stack multiplier i.e. harvesting one colonist and one prisoner will have a larger net debuff than harvesting from two colonists or two prisoners.

Immunity Gain Speed is helpful to survive [[infection]]s and other diseases; if it is 58% or lower, such as from two damaged kidneys, then even the [[Flu]] will be invariably fatal. Thus, it is recommended to replace damaged, destroyed or missing kidneys on valuable colonists as soon as possible.  
  
There are two primary reasons to harvest an organ - trade and transplantation.

[[Immunoenhancer]]s{{RoyaltyIcon}} can be implanted into pawns with natural kidneys. Each immunoenhancer will grant {{+|8%}} [[immunity gain speed]] to a pawn, which helps recovery from disease.

Harvesting from your own pawns is not recommended, so take from your prisoners or guests. For most pawns, the mood penalty of organ harvest is worth replacing the organ, but this may not apply to more disposable pawns.
Kidneys can be damaged by disease, drugs, or combat. The damage to a single kidney reduces Blood Filtration by up to 50%. This has two primary effects - the first is a 5% reduction in [[Consciousness]] which in turn affects almost every task a pawn can perform - making them slightly worse in basically every way.
 
  
The second, perhaps more urgent, effect is a 25% reduction in [[Immunity Gain Speed]]. This significantly reduces the survivability of infections and common diseases such as the [[Flu]]. If a pawn has an immunity gain speed of 58% or lower, such as from two damaged kidneys, or a damaged kidney and [[Liver]], then the flu will be invariably fatal.

[[Detoxifier kidney]]s{{BiotechIcon}} are a kidney replacement which can be crafted at a Fabrication bench once the [[Research#Toxin_filtration|Toxin filtration]] research project has been completed. Each detoxifier kidney requires {{Required Resources|detoxifier kidney}}. Installing a detoxifier kidney replaces the pawn's natural kidney.

Detoxifier kidneys have a part efficiency of {{good|110%}}, grant {{+|50%}} [[toxic resistance]], and are immune to [[chemical damage]] from drugs.

Toxic resistance from detoxifier kidneys will stack to a maximum of {{+|100%}} with 2 installed parts.

Each kidney is worth 250 silver, and only has a mass of 1.

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).

Acquisition[edit]

The kidney item can be harvested from live humans through surgery. The kidney must be perfectly healthy in order to obtain the item. This bill requires 1 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. Kidneys can be directly harvested, but installing a detoxifier kidney Content added by the Biotech DLC will also net an organic kidney. Removing both kidneys will kill the pawn.

Removing a kidney from a guest or prisoner will decrease faction goodwill by 80 points, down to the cap of -100. Removing any organ from anyone depresses the "donor" with -30 mood penalty for 7 days and 7 hours. Other colony members can give potentially tremendous mood penalties, which all stack:

−5 for "Someone's organ harvested" (any organ); −6 if colonist harvested
−6 for "Someone organ-murdered" (if fatal)
−5 for "Witnessed ally's death" (if fatal and on colonist / guest)

Pawns with the Bloodlust or Psychopath traits, or those with an Ideoligion with Organ Use: AcceptableContent added by the Ideology DLC are not affected by the harvesting of other people. Other Ideologion precepts may change moodlets for harvest and organ use.

Kidneys can also be acquired through trading with faction settlements or Exotic Goods traders.

Summary[edit]

A human requires 1 kidney to live. Each kidney accounts for 50% of a person's Blood Filtration. Blood Filtration itself affects Consciousness and Immunity Gain Speed; a completely removed kidney reduces Consciousness by 5% and Immunity Gain Speed by 25%. The Consciousness penalty reduces a variety of pawn capabilities.

Carcinoma, one form of tumor cancer, weakens blood filtration. Kidneys can also be damaged from physical injuries or chemically damaged from psychite tolerance.

Installation[edit]

Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal quality or better, and a Medical skill of 5.

Removing the part requires 2,000 ticks (33.33 secs) of work, 1x medicine of herbal quality or better, and has no Medical skill requirements.

If the operation fails, the part has a chance[What Chance?] to be destroyed.

Analysis[edit]

Immunity Gain Speed is helpful to survive infections and other diseases; if it is 58% or lower, such as from two damaged kidneys, then even the Flu will be invariably fatal. Thus, it is recommended to replace damaged, destroyed or missing kidneys on valuable colonists as soon as possible.

ImmunoenhancersContent added by the Royalty DLC can be implanted into pawns with natural kidneys. Each immunoenhancer will grant +8% immunity gain speed to a pawn, which helps recovery from disease.

Harvesting from your own pawns is not recommended, so take from your prisoners or guests. For most pawns, the mood penalty of organ harvest is worth replacing the organ, but this may not apply to more disposable pawns.

Compared to detoxifier kidney[edit]

Detoxifier kidneysContent added by the Biotech DLC are a kidney replacement which can be crafted at a Fabrication bench once the Toxin filtration research project has been completed. Each detoxifier kidney requires Plasteel 15 Plasteel, Advanced component 2 Advanced components. Installing a detoxifier kidney replaces the pawn's natural kidney. If the kidney is in perfect condition, it is harvested from the pawn with no negative consequences. ImmunoenhancersContent added by the Royalty DLC cannot be installed in a detoxifier kidney.

Detoxifier kidneys have a part efficiency of 110%, grant +50% toxic resistance, and are immune to chemical damage from drugs. Each detoxifier kidney increases blood filtration by +5%, which in turn increases immunity gain speed by +2.5%. Toxic resistance from detoxifier kidneys will stack to a maximum of +100% with 2 installed parts.

Trade[edit]

Each kidney is worth Silver 900 silver. While lungs are worth more than kidneys, you can harvest both a kidney and a lung without killing a pawn. If the mood penalties don't concern you (or don't exist due to IdeoligionContent added by the Ideology DLC), you can harvest 1 kidney, 1 lung, and 1 heart/liver before a pawn dies. This can extract a lot of value, almost certainly more than selling the pawn to a slaver.

You can also harvest a kidney and lung, then donate the prisoner to a royal tribute collectorContent added by the Royalty DLC for the same amount of honor as a healthy pawn.

Version history[edit]

  • 0.7.581 - Item form added, and now harvestable.
  • ? (Possibly 1.4) - Market value increased from Silver 250 silver to Silver 900 silver.
