What percentage of normal kidney function is replaced by hemodialysis?

Hemodialysis is a treatment designed to replace some of the kidney's functions, particularly the filtering of waste products and excess fluids from the blood. In patients with end-stage renal disease (ESRD), kidneys have lost the ability to function adequately, leading to the need for dialysis.

In practice, hemodialysis typically replaces about 10% to 15% of normal kidney function per treatment session. Therefore, the answer indicating 15% accurately reflects the average percentage of kidney function that is typically restored or supported through hemodialysis. This percentage can vary based on individual patient factors, the frequency of dialysis treatments, and the specific dialysis regimen being utilized.

Understanding this percentage is vital for healthcare professionals oversees managing patients on hemodialysis, as it can impact treatment planning and patient education. It also serves as a basis for discussions with patients about the role of dialysis in their overall health management.
