Cyberkidney
Description:
A cybernetic kidney replacement. Embrace the certainty of steel!
Available as a more affordable Cyber-augmented Kidney (half meat, half silicon) crafted from an extracted Kidney, or the twice as effective fully-synthetic Cyberkidney.
Advantages of Cyberkidneys:
- With the power of techology, you only need one!
- Resistance to
Blood loss and 
Bleeding - Switches blood type to C+, which can accept any other blood without
Hemotransfusion shock - Resistance to
Kidney damage
Disadvantages of Cyberorgans:
- Switches blood type to C+, whose cybernanites will cause Hemotransfusion shock if given to anyone else lacking cybernetic blood.
- Can periodically experience fits of Cyberpsychosis (regular psychosis), which can be avoided by reducing your Immunity in any way, such as the very affordable Immunosuppressant Inhaler.
How to Add:
Do 
Organ transplant surgery, using the Cyberkidney instead of a pair of feeble meat kidneys. Consider refrigerating the procured meat for upgrading into a Cyber-augmented Kidney.
