Why Is a Kidney Biopsy Performed?

A kidney biopsy is performed for several reasons, including:

  • Diagnosis of Kidney Diseases: To identify the specific type of kidney disease, such as glomerulonephritis, nephrotic syndrome, or interstitial nephritis.

  • Assessment of Kidney Function: To evaluate the extent of kidney damage in conditions like chronic kidney disease (CKD) or acute kidney injury (AKI).

  • Monitoring Transplanted Kidneys: To check for signs of rejection or other complications in patients who have had a kidney transplant.

  • Unexplained Kidney Problems: To investigate the cause of unexplained blood in the urine (hematuria), protein in the urine (proteinuria), or abnormal kidney function tests.
