New artificial kidney will reduce dialysis


Patients with renal failure are required to clean blood from toxic products abandonably, during dialysis — invasive and risky procedure. American scientists have successfully experienced a prototype of impaired artificial kidney, which does not require immunosuppressants or anticoagulants.

The kidney performs several important functions in the body, the most important of which is cleaning blood from the metabolic products, as well as the control of blood pressure, the concentration of electrolytes and other liquids in the body. Therefore, when this organ begins to refuse, all these processes are difficult to duplicate. Most often, patients are prescribed dialysis. In the long run, a branch transplant is required, which facilitates life, but brings with itself the risk of side effects from the reception of drugs for immunosuppression.

The device consists of two main parts: the hemofilter is made of a silicon semiconducting membrane that displays the metabolic products from the blood. The bioreactor consists of modified kidney channel cells and adjusts the volume of water, the balance of electrolytes and other metabolic functions. The membrane protects these cells from the attacks of the immune system,

The device is connected to two major arteries — one leads blood for filtering, the other transports it back into the body — as well as with the bladder, where the metabolic products fall.

Previous tests showed that each of these parts copes well with its task regardless of another, but together they were tested for the first time. Artificial kidney works effectively under blood pressure, without needing an additional source of energy. The kidney channel cells survived the test and performed their function to the end of the test.
