What it is
Chronic kidney disease means persistent abnormalities of kidney structure or function with health consequences.
Typical presentation
Many people have no symptoms until advanced disease.
Assessment
Estimated glomerular filtration rate and urine albumin, repeated over time, establish chronicity and risk.
Treatment approach
Management includes treating the cause, managing blood pressure and cardiovascular risk, kidney-protective drugs in eligible patients and monitoring for complications.
Key safety concern
Rapidly falling urine output, severe breathlessness, confusion or major fluid overload warrants urgent care.

Overview

Chronic kidney disease means persistent abnormalities of kidney structure or function with health consequences. The historical term chronic renal failure is less precise, particularly for earlier stages.

Symptoms and presentation

Many people have no symptoms until advanced disease. Fatigue, itching, swelling, appetite change and complications may develop later.

CLINICAL FEATURES

Presentation and warning signs

The pattern varies and cannot replace an individual assessment.

Clinical overview
Presentation
  • Many people have no symptoms until advanced disease
Clinical assessment
  • Estimated glomerular filtration rate and urine albumin, repeated over time, establish chronicity and risk
  • Interpret results with history and examination
When to seek urgent care
  • Rapidly falling urine output, severe breathlessness, confusion or major fluid overload warrants urgent care.

Emergency symptoms and clinical severity should be assessed locally.

Clinical assessment and diagnosis

Estimated glomerular filtration rate and urine albumin, repeated over time, establish chronicity and risk. Blood pressure, diabetes and other causes are assessed.

ASSESSMENT

How the clinical assessment proceeds

Exact investigations depend on the clinical context.

Clinical workflow
1Define the symptom patternMany people have no symptoms until advanced disease. Fatigue, itching, swelling, appetite change and complications may develop later.
2Assess disease or alternative causesEstimated glomerular filtration rate and urine albumin, repeated over time, establish chronicity and risk. Blood pressure, diabetes and other causes are assessed.
3Discuss care and monitoringManagement includes treating the cause, managing blood pressure and cardiovascular risk, kidney-protective drugs in eligible patients and monitoring for complications.
