Why Chronic Kidney Disease(CKD) without symptoms ?
Since about 180 liters of
ultrafiltrate is formed in the kidneys, it is possible to pass normal quantity of urine inspite of the kidneys being chronically damaged. So even when 90% of kidneys are damaged, there can be a normal urine output.
Disease of the kidneys often does not produce urinary symptoms when chronic. The body also adapts when a disease is
chronic.
