Kidney Biopsy: What It Is and What to Expect

How a kidney biopsy is done, why it is needed, and what recovery is like.

Last updated: 24/9/2026

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.
