Kidney Biopsy

How It Is Done continued...

The needle is removed after the tissue sample is taken. Pressure is put on the biopsy site for several minutes to stop the bleeding. Then a bandage is put on the site. The biopsy takes 15 to 30 minutes.

After the test

After the biopsy, you will rest in bed for 6 to 24 hours. Your pulse, blood pressure, and temperature will be checked often after the biopsy.

If no problems develop, you can go home. To prevent bleeding at the biopsy site, you will be told to lie down in a certain position for the next 12 to 24 hours. You may eat your normal diet. Do not take aspirin or anti-inflammatory medicines for a week after the biopsy. You may do your regular activities, but do not do strenuous activities, such as heavy lifting, hard running, motorcycle riding, contact sports, or other activities that might jar or jolt your kidney, for 2 weeks after the biopsy.

How It Feels

You may feel a brief sting or pinch when the numbing medicine is put in. When the biopsy needle is put in, you may feel a sharp pain for a few seconds.

It is normal to feel some muscle soreness in the area of the biopsy for 2 to 3 days after the biopsy. You may have a small amount of bleeding on the bandage after the biopsy. Talk to your doctor about how much pain and bleeding you can expect. Many people will have bright red blood in their urine for the first 24 hours after the biopsy; this is expected.
