Difference Between Hemodialysis and Peritoneal Dialysis

 Key Difference:In hemodialysis, blood is pumped out of your body to an artificially made kidney machine, and returned back to your body by cylinders that connect you to the machine. In peritoneal dialysis, the inside coating of your own stomach works as a natural filter. Wastes are taken out by using a purifying liquid called dialysate, which is washed all through your belly in cycles. 

The two most effective treatment alternatives for patients with end-stage renal ailment are hemodialysis and peritoneal dialysis. 

Dialysis is a method for cleaning your blood when your kidneys is unable to carry out its function effectively. It disposes of your body's waste, additional salt and water, and is helpful in controlling your blood pressure.


"Hemodialysis is a procedure of cleaning the blood of an individual whose kidneys are not working normally. This kind of dialysis accomplishes the extracorporeal expulsion of waste items, for example, creatinine and urea and free water from the blood when the kidneys are in a condition of kidney failure." 

HemodialysisHemodialysis can be an outpatient or inpatient treatment. Routine hemodialysis is performed in a dialysis outpatient facility, either a purpose-built room in an emergency clinic or a dedicated, independent facility.The number of hemodialysis done at home is very less. Dialysis treatments in a clinic are started and overseen by specialized staff made up of nurses and technicians; dialysis treatment at home can be self-initiated and managed or done together with the help of a trained helper who is generally a relative.


  • Limits freedom, as individuals undergoing this procedure can't go around due to supplies'availability. 
  • Requires more supplies, for example, high-water quality and power. 
  • Requires dependable technology like dialysis machines. 
  • The method is not very simple and necessitates that care givers have more information. 
  • Time talking to set up and clean dialysis machines, and cost with machines and related staff.


Peritoneal Dialysis

Peritoneal dialysis is a sort of dialysis which utilizes the peritoneum in an individual's stomach area as the membrane through which fluid and dissolved substances  are exchanged with the blood. It is utilized to evacuate excess fluid, solve electrolyte issues, and expel toxins in those with kidney failure.Peritoneal Dialysis

In peritoneal dialysis, a particular solution is introduced through a permanent tube in the lower abdomen of a person and after that evacuated. This may either happen at regular intervals for the whole duration of the day, known as continuous ambulatory dialysis, or at night time with the help of a machine, known as automated peritoneal dialysis. The solution is normally made of sodium chloride, hydrogen carbonate, and an osmotic agent such as glucose.


  •  The frequency of infections is as regular as once every 15 months (0.8 episodes per patient year). 
  • Complications may include infections inside the stomach area, hernias, high glucose, bleeding in the abdomen, and blockage of the catheter.There is no utility for those with abdominal surgery or inflammatory bowel disease.

Contrasted with hemodialysis, peritoneal permits more patient mobility, produces less swings in symptoms because of its consistent nature and phosphate compounds are better evacuated, yet a lot of  albumin are expelled which requires steady observing of nutritional status. The expenses of peritoneal dialysis are by and large lower than that of hemodialysis in many parts of the world, this cost preferred standpoint is most apparent in developed economies

Peritoneal dialysis may likewise be utilized for patients with cardiac instability  as it doesn't result in fast and significant changes to body fluids, and for patients with insulin dependent diabetes mellitus because of the failure to control glucose levels through the catheter.



Peritoneal Dialysis


In hemodialysis, blood is pumped out of your body to an artificial kidney machine, and returned to your body by tubes that connect you to the machine.

 In peritoneal dialysis, the inside lining of your own belly acts as a natural filter. Wastes are taken out by means of a cleansing fluid called dialysate, which is washed in and out of your belly in cycles.


Patient Mobility

Lesser pateient mobility.

Allows greater patient mobility.

Swings in symptoms

More swings as compared to peritoneal dialysis.

Produces fewer swings in symptoms due to its continuous nature.


Phosphate is not removed so effectively but albumin loss is lesser.

Phosphate compounds are better removed, but large amounts of albumin are removed.

Cost Effective

Less cost effective.

More cost effective.
