A kidney biopsy is a diagnostic test that involves collecting small pieces of kidney tissue, usually through a needle, for examination with a microscope. This procedure can help in making a diagnosis and in choosing the best possible treatment.
A biopsy can also help explain why a kidney is not working properly. Your doctor may prescribe a kidney biopsy to make a diagnosis in any of the following conditions:
– Hematuria, which is blood in the urine
– Proteinuria, which is excessive protein in the urine
– Impaired kidney function, which causes excessive waste products in the blood
After the procedure, you should rest in the hospital for a few hours. During this time, the staff will monitor blood pressure and pulse frequently. Most patients leave the hospital the same day. You may notice some blood in the urine for 24 hours after the test. A rare complication is uncontrolled bleeding.
You should inform the doctor if you have any of these problems:
