Kidney Biopsy: What It Is and What to Expect
How a kidney biopsy is done, why it is needed, and what recovery is like.
A kidney biopsy takes a tiny sample of kidney tissue with a thin needle so a pathologist can see exactly what is causing damage.
Why it is done
It diagnoses glomerular diseases, the cause of nephrotic syndrome, or unexplained kidney failure when blood and urine tests are not enough.
What to expect
Usually done under local anaesthetic with ultrasound guidance. Most people go home the same day and rest for a day or two.
Frequently Asked Questions
Is a kidney biopsy painful?
You may feel pressure and brief discomfort, but local anaesthetic keeps it tolerable.
