Stages of chronic kidney disease

Healthy kidneys Kidney disease stage 1: early stage Kidney disease stage 2: mild damage Kidney disease stage 3: moderate damage Kidney disease stage 4: severe damage End stage kidney disease

Chronic kidney disease progresses in 5 different stages.

Each stage of chronic kidney disease is related to the level of kidney function and kidney damage.

Stage 1 – a normal eGFR greater than or equal to 90 millilitres per minute per 1.73m2, and albuminuria, haematuria, a pathological abnormality or a structural abnormality.

Stage 2 – a slightly decreased eGFR between 60 and 89 millilitres per minute per 1.73m2, and albuminuria, haematuria, a pathological abnormality or a structural abnormality.

Note: If your kidney function is at stage 1 or 2, you only have chronic kidney disease if you have albuminuria, haematuria, a pathological abnormality or a structural abnormality.

Stage 3a – a mild to moderate decrease in eGFR between 45 and 59 millilitres per minute per 1.73m2.

Stage 3b – a moderate to severe decrease in eGFR between 30 and 44 millilitres per minute per 1.73m2.

Stage 4 – a severe decrease in eGFR between 15 and 29 millilitres per minute per 1.73m2.

Stage 5 – end-stage kidney disease, as eGFR decreases to less than 15 millilitres per minute per 1.73m2, or dialysis is started.

As chronic kidney disease progresses through the five stages, the images* above illustrate the severity of damage to the kidneys.
