A biopsy is a procedure to collect small pieces of tissue to look at under a microscope. A kidney biopsy may be done to check for problems or when other tests show a kidney problem. For example, you may get one if a test shows that you have blood or protein in your urine. The biopsy is usually done by putting a long, thin needle through the back and into the kidney. The doctor may do several biopsies to make sure there is a good sample.
The doctor may use ultrasound to guide the needle during the biopsy. The area will be numb.
The biopsy itself will take 15 to 30 minutes. The whole procedure will take about an hour. This includes cleaning the biopsy site and bandaging it.
After the procedure, you'll stay in the hospital or surgery centre for several hours to make sure there are no problems. Most people can go home the same day. You may need someone to drive you home.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
