Definition
One kidney can provide adequate function after congenital absence, donation or surgery.
Symptoms
Usually no symptoms; hypertension or urine albumin may develop.
How it may be discovered
Known since childhood or after an operation.
When to seek care
Arrange regular monitoring. Sudden urine reduction or pain with fever needs urgent assessment.
Investigations and tests
Blood pressure, estimated filtration and urine albumin; imaging when needed.
Reaching a diagnosis
Follow-up assesses remaining kidney function and trends, not kidney count alone.
Treatment options
Healthy habits, suitable medicines and activity-specific injury prevention; a restrictive diet is not routinely needed with normal function.
These kidney guides are educational. Medical kidney disease may require coordinated care with a nephrologist.
