The Pre-Dialysis Stage: Why Planning Ahead Matters
Posted 16 Jul 2026 | Source:

There is a stage in advanced kidney disease, before dialysis or a transplant becomes necessary, that is one of the most important periods in the whole journey. Often called the pre-dialysis stage, it is the window during which crucial decisions are made and preparations put in place. Using this time well can make a profound difference to how smoothly the next phase begins and how well things go thereafter. This article explains why this window matters so much and what should happen during it.

What is the pre-dialysis stage?

The pre-dialysis stage refers to the period of advanced kidney disease when kidney function has declined significantly but has not yet reached the point of needing kidney replacement therapy. During this time, the kidneys are still working, but the trajectory suggests that dialysis or a transplant will be needed at some point. It is, in effect, the preparation phase — the time to plan and ready everything for what may come, while there is still the breathing space to do so calmly.

Why this window is so valuable

The pre-dialysis window is valuable precisely because it is a time of choice and preparation rather than crisis. Decisions made calmly and with full information during this period are far better than decisions forced by an emergency. People who use this window well typically transition to the next phase smoothly, with everything in place; people who miss it often start treatment abruptly and unprepared, which is harder in every respect. The difference between these two experiences is largely determined by what happens during this stage.

What should happen during the pre-dialysis stage

Choosing the right treatment. A central task of this period is to learn about and choose between the options — haemodialysis, peritoneal dialysis, and transplantation. Each suits different lifestyles, circumstances, and preferences. Having time to understand them, ask questions, and reflect allows you to make a choice that fits your life, rather than having one imposed by timing. This is also the time to consider whether a transplant before dialysis might be possible, which is often the best outcome of all.

Preparing dialysis access in advance.

If haemodialysis is chosen, the preferred form of access — a connection in the arm called an arteriovenous fistula — needs to be created surgically and then takes weeks to months to mature before it can be used. Creating it well ahead of need means it is ready when required, avoiding the use of a temporary catheter, which carries more risks. If peritoneal dialysis is chosen, its access also needs to be placed in advance. Planning access ahead is one of the most concrete and important benefits of the pre-dialysis window.

Being assessed for transplantation.

This is the ideal time to be assessed for a transplant, including identifying a potential living donor if that is an option. A transplant performed before dialysis is needed — known as a pre-emptive transplant — generally gives the best results, and it is only possible if the assessment is done during this window.

Protecting remaining function and overall health. Throughout this period, efforts continue to protect whatever kidney function remains and to keep the body in the best possible condition: controlling blood pressure and diabetes, managing anaemia and bone health, attending to nutrition, completing vaccinations, and addressing other health issues. Entering the next phase in good general health leads to better outcomes.

Preparing practically and emotionally.

This window also allows time to prepare in practical terms — understanding how treatment will fit with work, family, and daily life — and emotionally, coming to terms with the situation with the support of family and the medical team. This preparation is valuable and often underestimated.

The cost of missing this window

When the pre-dialysis window is missed — often because kidney disease was not identified or referred until late — dialysis frequently has to be started as an emergency, through a temporary catheter, without the person having chosen their treatment or prepared for it. This “crash” start is associated with more complications, more time in hospital, and a harder adjustment. It is precisely what good use of the pre-dialysis window avoids. This is the strongest argument for being referred to a nephrologist early, well before this stage, so that the window is available to use.

Making the most of the window

If you are in this stage, the most useful thing you can do is engage actively with it. Ask about your options and take time to understand them. Raise the question of a transplant, and of a potential living donor, early. Ensure that any necessary access is planned in good time rather than left until the last moment. Keep your general health and other conditions well managed. And use the time to prepare yourself and your family. Working closely with your nephrologist through this period sets up everything that follows.

The pre-dialysis stage is a crucial window for planning and preparation. A nephrologist can guide you through your options and ensure everything is in place in good time. A video consultation is a convenient way to begin this planning.
