What Is Dialysis?
Dialysis is a treatment that takes over the role of the kidneys when they can no longer filter waste, toxins, and excess fluids from the blood. It is a life-saving solution for patients with advanced kidney disease, whether temporary or chronic. Dialysis helps the body maintain chemical and fluid balance and improves overall quality of life.
Through the ZagrebMed network, dialysis treatments are provided at B. Braun Avitum Polyclinic, a renowned partner that offers high-quality, modern care in line with European standards. This allows patients—both local and international—to receive timely treatment in a safe and professional environment.
Types of Dialysis
Hemodialysis
Hemodialysis is the most common form of dialysis and is performed outside the body using a dialysis machine. Blood is drawn from the patient, filtered through a dialyzer (artificial kidney), and returned to the body. Each session typically lasts four hours and is done three times per week in a hospital or outpatient center.
Peritoneal Dialysis
This method uses the body's own peritoneal membrane (in the abdomen) as a natural filter. A special fluid is introduced into the abdominal cavity through a catheter, absorbs waste products, and is then drained. Peritoneal dialysis is usually done at home, offering more independence and flexibility.
Continuous Renal Replacement Therapy (CRRT)
CRRT is a slower and continuous form of dialysis used in intensive care units for critically ill patients. It runs 24 hours a day, providing gentle and consistent waste removal, ideal for patients with low blood pressure or cardiac instability.
Problems Dialysis Can Solve
1. Toxin buildup (Uremia)
When kidney function declines, toxins like urea and creatinine accumulate in the blood, causing fatigue, nausea, confusion, and in severe cases, coma.
Solution: Dialysis clears these toxins, improving alertness and overall well-being.
Types used: Hemodialysis, Peritoneal Dialysis, CRRT
2. Fluid overload (Hypervolemia)
Fluid retention leads to swelling, high blood pressure, and shortness of breath.
Solution: Dialysis removes excess fluid and reduces symptoms.
Types used: Hemodialysis, CRRT
3. Electrolyte imbalances (e.g., Hyperkalemia)
High potassium or other electrolyte imbalances can cause life-threatening heart arrhythmias.
Solution: Dialysis restores normal electrolyte levels.
Types used: Hemodialysis, Peritoneal Dialysis, CRRT
4. Metabolic acidosis
A condition in which the body becomes too acidic due to impaired kidney function.
Solution: Dialysis helps maintain pH balance in the bloodstream.
Types used: Hemodialysis, Peritoneal Dialysis, CRRT
5. Anemia due to kidney disease
Low red blood cell production occurs when kidneys stop making enough erythropoietin.
Solution: Dialysis stabilizes the body, allowing for more effective anemia treatment.
Types used: Hemodialysis, Peritoneal Dialysis
6. Bone disease and high phosphate levels (Renal osteodystrophy)
Kidney failure disrupts calcium and phosphate balance, leading to weak bones and fractures.
Solution: Dialysis removes excess phosphate and supports mineral control.
Types used: Hemodialysis, Peritoneal Dialysis
The Importance of Timely Access to Dialysis
Kidney failure often progresses silently, with few symptoms until the disease reaches an advanced stage. This makes early detection and referral to a nephrologist critically important. Starting treatment on time, whether conservative care or dialysis, can significantly improve outcomes and delay complications.
Choosing the right dialysis method—hemodialysis, peritoneal dialysis, or CRRT—depends on each patient’s condition and lifestyle. With the ZagrebMed network, patients can access high-quality dialysis services without delays, including specialized care at B. Braun Avitum Polyclinic. In addition, early referral to a nephrology consultation is essential to assess risks, optimize treatment, and improve long-term kidney health.
