Chronic kidney disease (CKD) is a long-term condition in which kidney structure or function remains abnormal over time. As kidney function declines, the kidneys may eventually become unable to adequately remove waste, regulate fluid balance and maintain normal electrolyte and acid-base levels.
For selected patients with advanced kidney failure, peritoneal dialysis can provide kidney replacement therapy.
Unlike hemodialysis, which filters blood through a dialysis machine and an external circuit, peritoneal dialysis uses the patient's peritoneum, the lining of the abdominal cavity, as a natural filtering membrane.
Peritoneal dialysis can be performed at home for many patients and may offer greater flexibility in daily scheduling. However, it is not appropriate for everyone, and the choice of dialysis modality should be made after an individualized medical assessment.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized care for patients with chronic kidney disease, advanced kidney failure and kidney replacement therapy needs.
When Is Peritoneal Dialysis Considered in Chronic Kidney Disease?
Peritoneal dialysis is generally considered when kidney function has declined to the point that kidney replacement therapy is needed.
The decision is not based solely on one creatinine or eGFR value.
Doctors consider factors such as:
-
Symptoms caused by kidney failure
-
Fluid overload
-
Persistent electrolyte abnormalities
-
Acid-base disturbances
-
Difficulty controlling blood pressure or fluid balance
-
Reduced ability to maintain adequate nutrition
-
Overall kidney function
-
Other medical conditions
-
Patient preference
-
Home environment and support
-
Ability to perform dialysis safely
For many patients with progressive CKD, dialysis planning can begin before dialysis is urgently required.
How Does Peritoneal Dialysis Work?
The peritoneal membrane inside the abdomen contains many small blood vessels.
During peritoneal dialysis, a special dialysis solution is introduced into the abdominal cavity through a catheter.
Waste products and excess fluid move from the blood across the peritoneal membrane into the dialysis solution.
After remaining in the abdomen for a prescribed period, the used solution is drained and replaced with fresh solution.
This process is called an exchange.
Repeated exchanges help remove accumulated waste and excess fluid when the kidneys can no longer perform these functions adequately.
What Is a Peritoneal Dialysis Catheter?
A soft catheter is surgically placed into the abdomen before peritoneal dialysis begins.
The catheter provides a pathway for dialysis fluid to enter and leave the abdominal cavity.
Catheter care is extremely important because infection around the catheter or inside the abdominal cavity can interfere with treatment.
Patients are taught how to:
-
Keep the catheter area clean
-
Perform exchanges using appropriate technique
-
Recognize warning signs
-
Store dialysis supplies safely
-
Follow infection-prevention procedures
Types of Peritoneal Dialysis
There are two commonly used forms of peritoneal dialysis.
Continuous Ambulatory Peritoneal Dialysis (CAPD)
CAPD involves manual exchanges performed during the day.
The patient connects the dialysis solution to the catheter, allows the fluid to drain and then fills the abdomen with fresh solution.
The number and timing of exchanges are prescribed individually.
Because CAPD is performed manually, patients require appropriate training in sterile or aseptic exchange technique.
Automated Peritoneal Dialysis (APD)
APD uses a machine called a cycler to perform exchanges, commonly during nighttime while the patient sleeps.
The machine controls the filling, dwell and drainage cycles according to the prescribed treatment plan.
APD may provide more daytime flexibility for selected patients.
The most suitable modality depends on medical needs, lifestyle, home circumstances and the patient's ability to manage the treatment.
Benefits of Peritoneal Dialysis for CKD Patients
Peritoneal dialysis can provide several potential advantages.
Home-Based Treatment
Many patients can perform peritoneal dialysis at home after appropriate training.
This can reduce the need for frequent travel to a dialysis center.
Greater Scheduling Flexibility
Depending on the dialysis prescription, patients may have greater control over when treatment takes place.
No Routine Need for Vascular Access
Unlike hemodialysis, peritoneal dialysis does not require an arteriovenous fistula for treatment.
Instead, a peritoneal dialysis catheter is used.
Continuous Waste and Fluid Removal
Peritoneal dialysis provides repeated exchanges that can offer a more continuous form of kidney replacement therapy.
Preservation of Residual Kidney Function
For some patients, peritoneal dialysis may help preserve remaining kidney function for a period of time.
The degree of residual kidney-function preservation varies between individuals.
What Are the Risks of Peritoneal Dialysis?
Peritoneal dialysis is an established treatment, but it has potential complications.
Peritonitis
Peritonitis is an infection or inflammation of the peritoneal cavity.
Warning signs may include:
-
Abdominal pain
-
Fever
-
Nausea
-
Vomiting
-
Cloudy dialysis fluid
-
Feeling unusually unwell
Cloudy drained dialysis fluid should be reported promptly to the dialysis team.
Peritonitis requires timely medical assessment and treatment.
Catheter-Site Infection
Redness, swelling, tenderness or discharge around the catheter exit site can indicate infection.
Patients should report these changes promptly.
Hernia
Repeated increases in abdominal pressure can contribute to hernias in some patients.
A new lump or persistent discomfort around the abdomen or groin should be assessed.
Fluid or Glucose-Related Problems
Dialysis solutions contain specific concentrations of substances designed to remove excess fluid and waste.
Depending on the treatment prescription, patients may experience fluid-balance or blood-glucose issues.
The dialysis prescription can be adjusted according to individual needs.
Who May Be Suitable for Peritoneal Dialysis?
Peritoneal dialysis may be considered for patients with advanced kidney disease who:
-
Need kidney replacement therapy
-
Can perform the treatment safely or have appropriate assistance
-
Have suitable peritoneal function
-
Can maintain appropriate infection-control practices
-
Have an appropriate home environment
-
Prefer home-based dialysis when medically suitable
The decision must be individualized.
Who May Not Be an Ideal Candidate?
Peritoneal dialysis may be challenging for some patients.
Factors that may affect suitability include:
-
Extensive previous abdominal surgery
-
Severe abdominal adhesions
-
Certain abdominal diseases
-
Inability to perform exchanges safely
-
Lack of adequate home support when assistance is required
-
Certain severe medical conditions
These factors do not automatically rule out peritoneal dialysis. A nephrologist evaluates the individual circumstances before recommending a modality.
Peritoneal Dialysis vs Hemodialysis
Both treatments perform kidney replacement functions, but they work differently.
| Feature | Peritoneal Dialysis | Hemodialysis |
|---|---|---|
| Main filtering method | Peritoneal membrane | Dialysis machine and filter |
| Typical setting | Often home-based | Often dialysis center or home |
| Access | Peritoneal catheter | Vascular access |
| Treatment pattern | Repeated exchanges | Scheduled dialysis sessions |
| Patient involvement | Requires training and daily care | Depends on dialysis setting |
| Flexibility | Can offer home-based flexibility | Schedule varies by modality |
Neither treatment is universally better for every patient.
The choice should consider medical factors, lifestyle, home circumstances, patient preference and clinical suitability.
What Is Life Like During Peritoneal Dialysis?
Patients can often continue many normal activities while receiving peritoneal dialysis.
However, treatment becomes part of the daily routine.
Patients need to:
-
Follow the prescribed dialysis schedule
-
Maintain catheter hygiene
-
Store dialysis supplies appropriately
-
Follow dietary and fluid recommendations
-
Monitor body weight when advised
-
Attend regular nephrology appointments
-
Recognize symptoms of infection
-
Follow medication instructions
Travel may also be possible for selected patients with advance planning and coordination of dialysis supplies.
Diet and Fluid Management During Peritoneal Dialysis
Dietary requirements vary from one patient to another.
A renal dietitian or nephrologist may provide individualized recommendations regarding:
-
Sodium
-
Protein
-
Potassium
-
Phosphorus
-
Fluid
-
Calories
Peritoneal dialysis can result in protein losses through dialysis fluid, so adequate protein intake may be important for some patients.
However, dietary recommendations should be based on laboratory results, nutritional status and the dialysis prescription.
Avoid following generic online kidney diets without professional guidance.
Medicines During Peritoneal Dialysis
Patients with advanced CKD may require several medicines depending on their condition.
Treatment may address:
-
Blood pressure
-
Anemia
-
Mineral and bone abnormalities
-
Diabetes
-
Cardiovascular risk
-
Fluid retention
-
Other complications of kidney disease
Some medicines require dose adjustment because kidney clearance is reduced.
Always inform your nephrologist about prescription medicines, over-the-counter drugs, supplements and herbal products.
How Is Peritoneal Dialysis Monitored?
Regular monitoring helps determine whether the dialysis prescription is providing adequate treatment.
Follow-up may include:
-
Blood tests
-
Electrolyte monitoring
-
Hemoglobin testing
-
Nutritional assessment
-
Fluid-balance assessment
-
Blood-pressure monitoring
-
Weight monitoring
-
Residual kidney-function assessment
-
Dialysis adequacy assessment
-
Catheter-site examination
The dialysis prescription can be modified when clinical circumstances change.
Can Peritoneal Dialysis Improve Kidney Function?
Peritoneal dialysis does not repair permanently damaged kidneys.
Its purpose is to replace some of the functions that failing kidneys can no longer perform adequately.
If kidney failure is caused by an acute and potentially reversible condition, dialysis may sometimes be required temporarily while kidney function recovers.
In established end-stage kidney disease, dialysis is generally a long-term kidney replacement treatment unless the patient receives a successful kidney transplant.
Is Peritoneal Dialysis a Permanent Treatment?
It can be, but not necessarily.
Some patients use peritoneal dialysis for years.
Others may transition to:
-
Hemodialysis
-
Kidney transplantation
-
Another kidney replacement strategy
The treatment plan can change according to kidney function, complications, patient preference and overall health.
When Should a Peritoneal Dialysis Patient Contact the Doctor?
Patients should promptly contact their dialysis team if they notice:
-
Cloudy dialysis fluid
-
Abdominal pain
-
Fever
-
Catheter-site redness
-
Pus or discharge
-
Sudden swelling
-
Unexpected weight gain
-
Shortness of breath
-
Problems draining dialysis fluid
-
Leakage around the catheter
Early evaluation can help prevent complications from becoming more serious.
Can Peritoneal Dialysis Patients Work and Travel?
Many patients can continue working, studying and participating in daily activities after adapting to their treatment routine.
Travel may also be possible, but it requires planning.
Patients may need to arrange:
-
Dialysis supplies
-
Medical contacts
-
Adequate storage
-
Transportation
-
Emergency arrangements
Discuss travel plans with the dialysis team well in advance.
Kidney Transplantation and Peritoneal Dialysis
For suitable patients with kidney failure, transplantation may provide an alternative to long-term dialysis.
Some patients receive a transplant after starting peritoneal dialysis, while others undergo transplant evaluation before dialysis becomes necessary.
Transplant suitability depends on several factors, including overall health, cardiovascular status, infections, age, other medical conditions and transplant-center assessment.

Can a patient switch from peritoneal dialysis to hemodialysis?
Yes. Patients may transition between dialysis modalities when medically necessary or when circumstances change.
Can a person on peritoneal dialysis receive a kidney transplant?
Yes. Suitable patients can undergo kidney-transplant evaluation while receiving peritoneal dialysis.
Conclusion
Chronic kidney disease and peritoneal dialysis are closely connected when kidney function becomes advanced enough to require kidney replacement therapy. Peritoneal dialysis uses the body's peritoneal membrane to remove waste and excess fluid and can allow many appropriately selected patients to receive treatment at home.
The choice between peritoneal dialysis, hemodialysis, transplantation or other management approaches depends on kidney function, symptoms, medical conditions, lifestyle, home circumstances and patient preferences.
Understanding the treatment, maintaining catheter hygiene, following the dialysis prescription and recognizing early signs of complications are essential parts of successful peritoneal dialysis care.
