Renal biopsy is the procedure to carefully extract a tissue from the kidney for further analysis. This is a diagnostic test which helps your specialist identify the type of kidney problem as well as its severity and to decide on the right course of action for treatment. Kidney or renal biopsy can be performed either surgically or through percutaneous ways using a renal biopsy needle which is targeted to reach a specific part of the kidney guided using an ultrasound or ct imaging. One of the most common reasons to get a renal biopsy is to know if a kidney tumor is cancerous or not, to check the severity of kidney failure, etc.
