How Do I Prepare For A Kidney Biopsy

New kidney biopsy technique changes cancer diagnosis

Some medications can decrease blood clotting and increase the risk of bleeding during the procedure. You should stop taking these medications, including aspirin, warfarin, apixaban, ibuprofen, and other blood thinners and anti-inflammatory drugs at least one week before a kidney biopsy. Your doctor will ask about any other medicines or supplements you take and recommend any needed changes to your medication regimen.

Your doctor will take urine and blood samples before the biopsy to make sure you do not have any infections or other conditions that could cause complications. In most cases, doctors tell people not to drink or eat anything after midnight prior to the biopsy.

Itâs important to take other medication as usual on the day of biopsy. Blood pressure medication should be taken to avoid high blood pressure at the time of biopsy, and medicine may be taken with sips of water.

Preparing For The Procedure

  • You may need to stop eating and drinking before the day of the procedure. If this is the case, your doctor will tell you what to do.
  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
  • Make sure your doctor and the hospital have a copy of your advance directive. If you don’t have one, you may want to prepare one. It lets others know your health care wishes. It’s a good thing to have before any type of surgery or procedure.

What Are The Benefits Vs Risks

  • Needle biopsy is a reliable way to obtain tissue samples that can help diagnose whether a nodule is benign or malignant.
  • A needle biopsy is less invasive than open and closed surgical biopsies, both of which involve a larger incision in the skin and local or general anesthesia.
  • Generally, the procedure is not painful. Results are as accurate as when a tissue sample is removed surgically.
  • Recovery time is brief, and patients can soon resume their usual activities.
  • Any procedure that penetrates the skin carries a risk of infection. The chance of infection requiring antibiotic treatment appears to be less than one in 1,000.

Generally a biopsy procedure is safe and causes minimal injury. Complications that may result from biopsies include:

  • Bleeding
  • Infection
  • Accidental injury to adjacent structures such as the bowel during abdominal biopsy or lung parenchyma during renal biopsy

Considerations For A Renal Biopsy

Although renal biopsies are effective tools for diagnosing the presence or extent of kidney disease, there are problems associated with their use. One problem is that they produce false-negative results. Another is that they cannot be performed if kidney cancer is suspected, because the biopsies themselves can cause the spread of malignant cells. In the case of a known malignancy, removal of the tumor, or removal of the kidney , is recommended.

What Is A Transplant Kidney Biopsy


While a kidney biopsy is a procedure where small samples of the kidney are removed in order to be examined by a pathologist under a microscope. A transplant kidney biopsy is done either as a screening test or to see what is happening with a kidney that is not working properly. It provides more information than can be obtained from a noninvasive procedure . Biopsy is considered the best option to diagnose problems with transplanted kidneys.

  • go home the same day, in most cases however, a person will need to rest at home for 12 to 24 hours after the biopsy. Sometimes a person may need to stay overnight at the hospital.
  • have some pain or soreness near the point where the needle went through the skin.
  • receive written instructions for ensuring a healthy recovery from the procedure. Most people need to wait 2 weeks before resuming strenuous activities, such as heavy lifting or participating in contact sports.

A health care provider most often receives the complete biopsy results from the pathologist in about a week. In urgent cases, a person may receive a preliminary report within 24 hours. The health care provider will review the results with the person during a follow-up visit.

What Happens During A Kidney Biopsy

During a kidney biopsy, a doctor collects a sample of tissue from your kidney. Most biopsies are done through your back, although people with a transplanted kidney have the biopsy through their lower abdomen .

Your doctor will use one of these methods to take the sample:

  • Percutaneous biopsy: In this more common type of kidney biopsy, a doctor numbs the skin located over the kidney and inserts a needle to take a small tissue sample from the kidney. Your doctor may use ultrasound imaging to guide the needle to the best location in the kidney.
  • Open biopsy: In an open biopsy, a doctor makes an incision , removes tissue from the kidney, and closes the incision with stitches. Your doctor will give you anesthesia so you do not feel pain during the procedure. This type of biopsy is rare except at the time of kidney transplant.

How The Test Is Performed

Kidney Biopsy

A kidney biopsy is done in the hospital. The two most common ways to do a kidney biopsy are percutaneous and open. These are described below.

Percutaneous biopsy

Percutaneous means through the skin. Most kidney biopsies are done this way. The procedure is usually done in the following way:

  • You may receive medicine to make you drowsy.
  • You lie on your stomach. If you have a transplanted kidney, you lie on your back.
  • The doctor marks the spot on the skin where the biopsy needle is inserted.
  • The skin is cleaned.
  • Numbing medicine is injected under the skin near the kidney area.
  • The doctor makes a tiny cut in the skin. Ultrasound images are used to find the proper location. Sometimes another imaging method, such as CT, is used.
  • The doctor inserts a biopsy needle through the skin to the surface of the kidney. You are asked to take and hold a deep breath as the needle goes into the kidney.
  • If the doctor is not using ultrasound guidance, you may be asked to take several deep breaths. This allows the doctor to know the needle is in place.
  • The needle may be inserted more than once if more than one tissue sample is needed.
  • The needle is removed. Pressure is applied to the biopsy site to stop any bleeding.
  • After the procedure, a bandage is applied to the biopsy site.

Open biopsy

In some cases, your doctor may recommend a surgical biopsy. This method is used when a larger piece of tissue is needed.

Your doctor will have the results from your biopsy within a week.

How Is A Kidney Biopsy Performed

The procedure typically takes about an hour and includes the following steps:

For people with bleeding problems, the health care provider uses a laparoscopea thin tube with a video camera. This procedure is surgery that requires general anesthesia. The surgeon makes a small incision into the back and inserts the laparoscope to see the kidney. The surgeon can insert tiny tools through the laparoscope to collect tissue samples and can watch after the procedure through the camera to make sure that if there is any bleeding, he or she can stop it.

How Is The Sample Obtained In A Transplant Kidney Biopsy

There are two ways to obtain the sample during a transplant kidney biopsy. A needle can be used that will go through the skin and into the kidney. The needle then is used to collect the sample. An ultrasound image is used to help guide the needle to the correct spot. This process is called a percutaneous biopsy. The second method would be to take a sample during surgery, this is much less common. Ultrasound guided transplant kidney biopsies are most often done under local anesthesia.

What Happens After The Kidney Biopsy

Your recovery will vary depending on the type of procedure done and yourhealthcare provider’s practices. You may be taken to the recovery room andwatched closely as the anesthesia wears off. Once your blood pressure,pulse, and breathing are stable and you are alert, you may be taken to ahospital room or discharged to your home.

You will be asked to lie on your back for several hours. A nurse will checkyour urine for signs of bleeding. You may have blood tests to check forinternal bleeding. You may be discharged later the same day or the nextday. If you had a sedative or anesthetic, plan to have someone drive youhome.

The biopsy site may be tender or sore for several days after the biopsy.Take a pain reliever for soreness as advised by your healthcare team. Youmay need to avoid aspirin or certain other pain medicines that may raisethe chance of bleeding. Be sure to take only recommended medicines.

The risks of a kidney biopsy include

  • bleedingthe most common complication of a kidney biopsy. Bleeding may come from the kidney or the puncture site. Bleeding from the kidney rarely requires a blood transfusion.

How Is It Done

Web Episode #025b – Kidney Biopsy Hands-on Demonstration

Your kidneys lie just under the ribcage, towards the side and back of your upper tummy . So, you will usually be asked to lie on your front on a couch or bed. The skin over a kidney is cleaned with antiseptic. Local anaesthetic is then injected into a small area of skin and tissues just over the kidney to be sampled . This stings a little at first but then makes the skin numb.

If the biopsy is of a transplanted kidney, you will be asked to lie on your back and the local anaesthetic is put into the skin over the transplant.

A special hollow needle is then pushed through the skin and muscle into the kidney tissue to obtain a small sample. Because of the local anaesthetic, you should not feel any pain. However, you may feel some pressure as the doctor pushes on the needle. The needle is inserted and withdrawn quickly, bringing with it a small sample of kidney tissue.

You will have to hold your breath for 5-10 seconds when the needle is pushed in and out . This is because the kidneys move slightly when you breathe in and out.

During the biopsy an ultrasound scanner is often used to help the doctor. The ultrasound scan locates the kidney so the biopsy needle is inserted at exactly the right place. The scan is painless.

Why Is A Transplant Kidney Biopsy Performed

A transplant kidney biopsy is done either to screen for otherwise undetected problems with the kidney or when there are signs that the kidney is not working well. Kidney disease can occur anytime after the transplant, and biopsies can help with diagnosing and treating these problems. Signs of problems may include little or no urine output, fever, high blood pressure, and abnormal lab values. These could include an increasing serum creatinine level. Other signs may include blood or protein in the urine, damage to the filtering parts of the kidney or kidney disease with no clear reason. A biopsy may detect rejection of the kidney before actual signs are seen, improving the chance of better long term outcomes.

After A Kidney Biopsy

You will need to lie on a bed and be observed for several hours to check that you have no bleeding. So, you may wish to bring in a book or a music player for this time. If you come into hospital for the test, you may need to stay in overnight. However, if the sample was done early in the morning, you may be able to go home later in the day. You may have some discomfort which is usually eased by painkillers. The result of the biopsy may take a week or so to come back.

Your doctor may advise you not to take part in contact sports such as rugby for a certain length of time after the procedure. This is to make sure the kidney has a chance to heal properly.

You should seek medical advice if:

  • Your urine appears blood-stained.
  • You develop tummy pain.
  • The biopsy site becomes red or angry looking.
  • You develop a high temperature .
  • The biopsy site is still painful three days later and painkillers do not help.

Why Have A Kidney Biopsy

Your doctor may need to do a kidney biopsy to find out why your kidneys are not working well or why there is blood or protein in your urine. While a blood test and a urine test are the most common ways to test for kidney disease, a kidney biopsy can tell your doctor if you have other rare conditions that are damaging your kidneys, such as focal segmental glomerular sclerosis .

Doctors also use kidney biopsies to:

  • Monitor how quickly kidney damage is getting worse
  • Check how well your transplanted kidney is working
  • Find out why your transplanted kidney is not working properly
  • Create treatment plans based on the condition of your kidneys
  • Find out how well treatments are working
  • Diagnose cancer

A Mass Or Lump Around Your Abdomen

Hysteroscopy, endometrial biopsy order has no effect on pain

A mass or lump in the abdomen, side, or back can also be a sign of kidney cancer. You might feel a hard thickening or bulging bump under your skin.

But kidney lumps are hard to feel, especially in the early stages. Thats because the kidneys sit deep in the abdomen. You may not even see or feel the lump as the tumor grows.

If you do discover a lump, a doctor or other HCP will likely order diagnostic tests, such as an ultrasound or a CT scan. These tests may help determine the cause of the lump. Youll typically need a biopsy to confirm the diagnosis.

Keep in mind that not all lumps are cancer. If youre concerned about a lump around your abdomen, a doctor or other HCP can offer guidance and information about next steps.
