Kidney failure occurs when the kidneys lose their ability to filter waste, regulate fluid levels, and maintain the delicate balance of salts and minerals in the body. In its early stages, kidney dysfunction can be managed with strict care and lifestyle changes. However, when the damage becomes irreversible and the kidneys lose over 85–90% of their function, it reaches the terminal stage.
At this point, we refer to it as terminal kidney failure. This condition means the body can no longer sustain itself without external support. For most, the only paths forward are ongoing dialysis or a kidney transplant. But not all patients qualify for these options. Age, comorbidities, and lack of a donor match can close the door on treatment.
Even with dialysis, life expectancy is limited, especially when complications arise. Fatigue, fluid retention, nausea, cognitive decline, and cardiovascular strain are common and progressively worsening. And despite the best care, the burden on quality of life becomes overwhelming for many.
The emotional weight of an irreversible diagnosis
Being told that nothing more can be done is one of the hardest moments in any person’s life. For patients and families facing terminal kidney failure, the conversation often shifts from treatment to comfort.
The emotional experience is layered. There’s the physical toll of the illness, but also the psychological grief of what is lost, the sense of time running out, plans left unfulfilled, and the reality of saying goodbye. Some patients reach a place of acceptance, while others continue to search for options beyond the current framework.
This search isn't about denying reality. It's about exploring every path that aligns with personal values, beliefs, and the desire for continuity, even in the face of death.
Current treatment boundaries
Today, options for kidney failure at the terminal stage remain deeply limited:
Dialysis: a process that filters the blood artificially, replacing kidney function. It prolongs life but is physically draining and does not reverse damage.
Transplantation: effective, but dependent on donor availability, compatibility, and patient suitability.
Conservative care: symptom management without dialysis, often for those ineligible or choosing not to undergo further invasive support.
Unfortunately, none of these address the core issue: the kidney's inability to regenerate or restore its function naturally. Even with remarkable improvements in regenerative research, we’re still far from being able to rebuild organs in situ for those who need them most.
This is where some people begin to consider cryopreservation, not as an alternative to care, but as a long-term investment in time.
What is cryopreservation?
Cryopreservation is the process of cooling a legally deceased person to extremely low temperatures in order to stop all biological activity, with the aim of preserving the body’s structure and identity intact. The hope is that, in the future, advanced technologies will make it possible to repair or replace failing organs and revive individuals.
The process includes:
Stabilization: after legal death, steps are taken to preserve brain function and protect tissues from damage.
Cryoprotectans' perfusion: blood is replaced with a cryoprotective solution to prevent ice formation during cooling.
Cooling: the body is gradually cooled to cryogenic temperatures (around -196°C), where all cellular activity stops.
Long-term storage: individuals are kept in cryogenic conditions, awaiting future capabilities that may allow for revival and repair.
It’s essential to understand that cryopreservation is not a cure for kidney failure or any other disease. It is a bet on future progress—a way to bridge the time between current limitations and potential breakthroughs.
Terminal kidney failure and cryopreservation: the link
In the context of terminal kidney failure, cryopreservation presents a philosophical and technical opportunity. For individuals who have exhausted all current treatment paths, and who do not wish to accept biological death as final, it offers a structured approach to preserve life’s potential.
This isn’t science fiction. The technologies that allow us to preserve cells, tissues, and even certain organs for transplantation already exist. Cryopreservation scales this up to the entire body, preserving brain structure, identity, and all biological systems—including those damaged by disease.
In this scenario, the goal is not to pause a cure—but to preserve the possibility of a cure. For someone whose life is ending because of kidney failure, cryopreservation may offer a kind of time capsule—a scientifically grounded attempt to hold on until organ regeneration, whole-body repair, or more radical forms of biological restoration become viable.
Limitations and ethics
Choosing cryopreservation is not a simple or emotional decision, it’s a deliberate and informed choice. It's also a deeply personal one. There are ethical, financial, and logistical factors to weigh:
- Cryopreservation is currently speculative; no person has yet been revived after preservation.
- There is no guarantee of future revival or healing of kidney failure, or any other condition.
- It requires legal consent and logistical preparation in advance of legal death.
- Families may have differing views on its value, meaning, or spiritual implications.
What matters most is informed consent and transparent expectations. Cryopreservation isn’t about selling hope—it’s about offering agency in a situation where options are disappearing. For some, that agency alone is enough.
Making sense of the future
The experience of kidney failure, especially at the terminal stage, is devastating. It affects not just the person diagnosed, but everyone around them. No one wants to face the reality of time running out.
But in that very reality, some look toward cryopreservation as a bridge. A way of saying: “This is not the end. Not yet.” It is a pause, not a promise. A hope, not a cure. But in a world where progress accelerates daily, hope rooted in science is a powerful thing.
At Tomorrow.bio, we are here to offer guidance. We know how hard a diagnosis of terminal kidney failure can be. We’ve spoken to families, patients, and professionals navigating impossible choices. Our role is not to replace care or decisions, but to provide information, transparency, and support.
If you want to know more about how cryopreservation works, what it can and cannot do, or what the process involves, we're here to explain it all—openly and honestly.
Because when all other roads close, it helps to know there’s still one that leads forward.
About Tomorrow.bio
At Tomorrow.bio we are dedicated to advancing the science of cryopreservation with the goal of giving people a second chance at life As Europe’s leading human cryopreservation provider we focus on rapid high-quality standby, stabilization and storage of terminal patients preserving them until future technologies may allow revival and treatment.
Our mission is to make human cryopreservation a reliable and accessible option for everyone We believe that no life should end because current capabilities fall short.
Our vision is a future where death is optional where people have the freedom to choose long-term preservation in the face of terminal illness or fatal injury and to awaken when science has caught upInterested in learning more or becoming a member
