A kidney biopsy, also called renal biopsy, is a procedure to remove a small piece of kidney tissue so that it can be examined under a microscope for signs of damage or disease. Your doctor may recommend a kidney biopsy if blood tests, urine tests or imaging techniques don't provide enough information to diagnose a kidney problem. A kidney biopsy may also be used to determine the severity of kidney disease or to find out if treatment for kidney disease is working. You may need a kidney biopsy if you've had a kidney transplant that's not working properly.

Most kidney biopsies are performed by inserting a thin needle through the skin. In this procedure, an imaging device helps guide the needle into one of your kidneys to remove tissue.

A kidney biopsy may be done to:

Your doctor may recommend a kidney biopsy based on the results of blood or urine tests. Some common reasons for kidney biopsy include:

Not everyone with these problems needs a kidney biopsy. The decision is based on your signs and symptoms, test results and overall health.

n general, percutaneous kidney biopsy is a safe procedure. Possible kidney biopsy risks include:

How you prepare

By Mayo Clinic staff

Before your kidney biopsy, you'll meet with your doctor to talk about what to expect. This is a good time to ask questions about the procedure and make sure you understand the risks and benefits.

Medications
When you meet with your doctor, bring a list of all medications you take, including over-the-counter medications, vitamins and herbal supplements. Before your kidney biopsy, you'll be asked to stop taking medications and supplements that can increase the risk of bleeding. These include:

Your doctor or nurse will let you know when to stop taking these medications and supplements, and for how long.

Blood and urine samples
Before your biopsy, you'll have blood drawn and provide a urine sample to make sure you don't have an infection or another condition that would make the biopsy risky.

Diet
You may be asked not to drink or eat for eight hours before the kidney biopsy.

What you can expect

By Mayo Clinic staff

A kidney biopsy is done at a hospital or outpatient center. Your health care team will review your medical history, including the medications you take. Just before your biopsy, you'll undress and put on a hospital gown. You may be given a light sedative to help you relax during the procedure.

During the procedure
During a kidney biopsy, you'll be fully awake and lying on your stomach, so your kidneys are positioned near the surface of your back. If the biopsy is for a transplanted kidney, you'll lie on your back instead. A percutaneous biopsy takes about an hour for the entire process and follows this sequence:

Other kidney biopsy procedures
Percutaneous kidney biopsy isn't an option for some people. If you have a history of bleeding problems, have a blood-clotting disorder or had a kidney removed, your doctor may use a laparoscopic biopsy. In this procedure, your doctor makes a small incision and inserts a thin, lighted tube with a video camera at its tip (laparoscope). This tool allows the doctor to view your kidney on a video screen and remove tissue samples.

After the procedure
After the biopsy, you can expect to:

Most people can leave the hospital the same day. Some people need to rest in bed for 12 to 24 for hours after the biopsy, as directed by their doctor. Your health care team will let you know about any restrictions you need to follow after the biopsy. For example, you should avoid heavy lifting and strenuous exercise for two weeks.

Your kidney tissue goes to a laboratory to be examined by a doctor who specializes in diagnosing disease (pathologist). The pathologist uses microscopes and dyes to look for unusual deposits, scarring, infection or other abnormalities in the kidney tissue.
