dialyysiin

Dialyysiin is the Finnish term for dialysis, a medical procedure that substitutes some kidney functions by removing waste products and excess fluids from the blood when the kidneys no longer work adequately. Dialysis can be started after acute kidney injury or used as a long-term treatment for chronic kidney disease. The goals are to prevent toxin buildup, balance electrolytes, control fluid status, and maintain quality of life.

There are two main modalities: hemodialysis and peritoneal dialysis. Hemodialysis uses a dialysis machine and an artificial kidney (dialyzer) connected to the bloodstream through a vascular access site, such as an arteriovenous fistula, graft, or catheter. Treatments are usually performed in a hospital or dialysis center, though home hemodialysis is possible with training. Sessions typically occur several times per week and last several hours.

Peritoneal dialysis uses the body's peritoneal membrane as the filter. A cleansing solution (dialysate) is introduced into the abdomen through a catheter, allowed to dwell, and then drained. It can be done manually during the day (continuous ambulatory peritoneal dialysis) or automatically at night (automated peritoneal dialysis). This modality offers independence for some patients but requires daily management and infection precautions.

Dialysis does not cure kidney disease but can extend life and relieve symptoms. It is often used while awaiting a kidney transplant, which offers the best long-term outcome for eligible patients. Ongoing medical follow-up is needed to manage complications, nutrition, and access health. Availability, cost, and patient choice influence who receives dialysis and where.
