What is the purpose of renal replacement therapy?

The purpose of renal replacement therapy is to replace the function of the kidneys in patients who are experiencing kidney failure. When the kidneys are unable to adequately filter waste products, excess fluids, and electrolytes from the blood, renal replacement therapy becomes necessary to maintain homeostasis and prevent complications associated with kidney failure. This therapy can involve methods such as dialysis, which directly filters the blood, or kidney transplantation, where a healthy kidney is provided from a donor.

In nephrology, the primary goal of renal replacement therapy is to help manage the buildup of toxins in the bloodstream, control fluid balance, and maintain electrolyte levels, which are crucial for overall bodily function. Thus, it plays a vital role in supporting patients who have lost significant kidney function and are at risk for complications if left untreated.
