Why did willen kolff invent kidney dialysis?

Willem Kolff did not invent kidney dialysis, but he was a pioneer in the field of hemodialysis. In the 1940s, Kolff developed and constructed the first artificial kidney, a device that could remove waste products and excess fluid from the blood of patients with kidney failure. This invention significantly improved the treatment options for patients with severe kidney disease and paved the way for the later development of more sophisticated dialysis machines.
