Frequently Asked Questions
(FAQs)
What is a renal biopsy, and why is it done?
A renal biopsy involves taking a small sample of kidney tissue to examine under a microscope. It helps diagnose kidney diseases, evaluate the extent of kidney damage, and guide treatment plans.
Is a renal biopsy painful?
The procedure is usually performed under local anesthesia, so you may feel pressure but not pain. Some discomfort or soreness might occur afterward, but pain management options are available.
How long does a renal biopsy take?
A renal biopsy typically takes about 30 to 60 minutes. Most of this time is spent on preparation,
positioning, and after-care monitoring.
What are the risks associated with a renal biopsy?
Though generally safe, the procedure does carry some risks, including bleeding, infection, or
injury to the kidney. These risks are rare and are closely monitored by the medical team.
When will I get the results of my biopsy?
Biopsy results typically take a few days to a week, depending on the complexity of the tests
required. Your doctor will explain the findings and discuss the next steps.
Can I go home the same day after a renal biopsy?
Yes, most renal biopsies are outpatient procedures, meaning you can go home the same day.
However, you will need someone to drive you home, as you may feel drowsy from sedation.
Is there a risk of permanent kidney damage from a renal biopsy?
The chances of long-term kidney damage are extremely rare. The procedure is designed to be as
safe as possible, with the sample being taken from a small, specific area of the kidney.
Will I need to take time off work after a renal biopsy?
It’s recommended to rest for 24 to 48 hours after the procedure. Depending on your job,
especially if it involves heavy lifting or strenuous activity, you might need a little more time
before returning.
Is a renal biopsy different for kidney transplant patients?
Yes, in kidney transplant patients, the biopsy helps monitor the function of the transplanted
kidney and detect signs of rejection or complications.
