Does Kidney Biopsy Cause Damage to the Kidney?

Question

Recently, my child has been disobedient and crying a lot without any apparent reason. The examination results are inconclusive. I would like to ask whether kidney biopsy can cause damage to the kidneys.

Answer

Kidney biopsy only involves a small amount of kidney tissue and usually does not cause significant damage to the kidney. However, before performing a kidney biopsy, it is necessary to confirm that urine protein levels are 3+ or higher, both kidneys are of normal size, and blood tests are normal. Only under these conditions is kidney biopsy safe and necessary. It is recommended to consult with a kidney specialist.
