Kidney Biopsy (Renal Biopsy) is a procedure often necessary to diagnose and treat problems affecting the kidney.

What to Expect 

Patients usually require a 23 hour hospital stay after a renal biopsy. You will come to the hospital and have an IV placed and sign any necessary forms. At this time you may be given a medicine ordered by your physician to help you relax. You will then be transported to the ultrasound department where the procedure will be done. You will lie face down on a table and the skin in the lower back will be cleaned and numbed with lidocaine. While viewing the kidney under ultrasound, pieces will be taken off the top of 1 kidney using a needle. A pathologist will also be there to check that the tissue is from the correct part of the kidney. After the procedure, you will have to lie in bed for 6 hours and be monitored for any signs of bleeding. 

What to Do 

Do not take any aspirin or other anti-inflammatory medications for 1 week before the procedure. Arrive at the hospital at the time specified by your physician. You may eat or drink on the morning of the procedure.
