A kidney failure diagnosis brings uncertainty, but renal replacement therapy offers a path forward. Dialysis performs the essential functions your kidneys no longer can, allowing you to maintain a full life.
This guide explores your options, as the right treatment depends on your medical needs and lifestyle. Our roadmap empowers you to choose a path that fits your future.
What is Renal Replacement Therapy?
Before we examine the specific types, it’s important to understand the bigger picture. When your kidneys fail, they can no longer effectively filter waste products and excess fluid from your blood. Renal replacement therapy is the umbrella term for any treatment that takes over this essential job.
While a kidney transplant is one form of this therapy, dialysis is the most common. It is a life-sustaining treatment that manages your condition, allowing you to continue living a full life.
The Two Main Pillars of Dialysis
All forms of dialysis fall into two primary categories, distinguished by how they filter your blood.
- Haemodialysis (HD): Uses an artificial kidney machine (a dialyser) to filter your blood outside of your body.
- Peritoneal Dialysis (PD): Uses the natural lining of your own abdomen (the peritoneum) as a filter inside your body.
Let’s look at each of these in greater detail.
Understanding Haemodialysis (HD)
Haemodialysis is a process where your blood is circulated through an external machine (a dialyser) to be cleaned and then returned to your body. To begin treatment, a specialist creates an “access” point, typically a fistula or graft in the arm, which allows needles to safely draw and return your blood.
Patients can choose from several flexible environments and schedules:
- In-Centre Haemodialysis: Performed at a specialized unit, like Advanced Renal Care, usually three times a week for four hours. You are closely monitored by a clinical team.
- Home Haemodialysis (HHD): Offers the flexibility to perform your own treatment at home after comprehensive training.
- Mobile Renal Care: Treatment is brought directly to you, which is ideal for those with mobility challenges or living in assisted facilities.
- Nocturnal Dialysis: An overnight option lasting 6–8 hours while you sleep. This method is often gentler on the body and keeps your daytime hours fully available.
Understanding Peritoneal Dialysis (PD)
Peritoneal dialysis is an effective treatment that offers greater independence by using your body’s own abdominal lining (the peritoneum) to filter waste. A small tube, or catheter, is surgically placed in your abdomen to allow a cleansing fluid called dialysate to flow in and out. This process of filling and draining is known as an exchange.
There are two primary ways to perform these exchanges:
- Continuous Ambulatory Peritoneal Dialysis (CAPD): A manual, machine-free method performed about four times a day. Each exchange takes 30–40 minutes, allowing you to remain active in between.
- Automated Peritoneal Dialysis (APD): Uses a machine called a “cycler” to perform exchanges automatically while you sleep, usually over a period of 8–10 hours, leaving your daytime completely free.
Comparing HD and PD: Choosing the Right Fit
Deciding between Haemodialysis (HD) and Peritoneal Dialysis (PD) involves weighing clinical efficiency against your personal lifestyle. While HD is highly powerful and structured, PD offers a gentler, more continuous approach.
Key factors to consider include:
- Lifestyle & Flexibility: In-centre HD follows a fixed schedule (usually three times a week), providing a set routine. PD offers more spontaneity, making it ideal for those who work or travel, though it requires space at home for supply storage.
- Medical Suitability: HD is a fast, efficient blood-cleansing method. PD is a slower, more constant process that may better preserve any remaining natural kidney function.
- Patient Responsibility: In-centre HD is managed by clinical staff, requiring you only to attend appointments. Conversely, Home HD and all PD options require you to take charge of your own sterile procedures and health monitoring.
Choosing the Right Treatment for Your Life
The “best” dialysis is the one that aligns with your medical needs and lifestyle. At Advanced Renal Care, we partner with you to find the right fit by considering these key questions:
- Values: Do you prefer a structured clinical schedule or daily independence?
- Support: Do you have a reliable support system for home-based therapy?
- Comfort: Are you willing to manage your own treatment, including needles or catheters?
- Commitments: How does treatment fit with your work, family, and social life?

What is the best type of dialysis to choose?
There is no single “best” type. The optimal choice depends on your medical condition, lifestyle, and personal comfort. Haemodialysis in a centre offers clinical support, while peritoneal dialysis provides more independence. You should make the decision in close consultation with your nephrologist.
Does dialysis hurt?
The dialysis process itself is not painful. For haemodialysis, there may be some discomfort when the needles are inserted into your access point, but this is brief. For peritoneal dialysis, there is no pain associated with the exchanges.
How long can a person live on dialysis?
Many people live for decades on dialysis. It is a life-sustaining treatment, and life expectancy depends more on your overall health, age, and adherence to your treatment plan than on the dialysis itself. With good care, you can live a long and productive life.
Can you still work while on dialysis?
Absolutely. Many patients continue to work full-time. Peritoneal dialysis and nocturnal haemodialysis are often excellent options for working individuals because they free up the daytime. We can help you find a treatment schedule that fits your professional life.
What are the main side effects of dialysis?
Common side effects of haemodialysis can include low blood pressure, muscle cramps, and fatigue, especially right after a session. Peritoneal dialysis carries a risk of infection at the catheter site or in the abdomen (peritonitis), which requires strict hygiene to prevent. Your clinical team will help you manage any side effects.
