What to Expect after a Kidney Biopsy?

The following is a list of what happens after a kidney biopsy:

- Be taken to a recovery room where your blood pressure, pulse and breathing will be monitored. In addition, a urinalysis and complete blood count will be done to check for bleeding and other complications.
- Rest quietly on your back - or your stomach if you have a transplanted kidney - for several hours. You can eat and drink after the procedure.
- Be given written instructions about your recovery.
- Feel some soreness or pain at the biopsy site for a few hours. You'll be given medications to relieve pain.

Most people can leave the hospital the same day. Some people need to rest in bed for 12 to 24 for hours after the biopsy, as directed by their doctor. Your health care team will let you know about any restrictions you need to follow after the biopsy. For example, you should avoid heavy lifting and strenuous exercise for two weeks.

Your kidney tissue goes to a laboratory to be examined by a doctor who specializes in diagnosing disease (pathologist). The pathologist uses microscopes and dyes to look for unusual deposits, scarring, infection or other abnormalities in the kidney tissue.

Call your doctor if you experience:
- Significant bright red blood or clots in your urine more than 24 hours after the biopsy
- Inability to pass urine
- Fever
- Worsening pain at the biopsy site
- Fever over 100.4 F (38 C)
- Faintness or weakness
