Renal biopsies

A renal biopsy is a medical procedure that involves taking a small sample of kidney tissue for laboratory analysis. This helps doctors diagnose and understand kidney problems, such as inflammation, scarring, or disease, by examining the tissue under a microscope. The procedure usually involves inserting a thin needle through the skin into the kidney, guided by imaging like ultrasound. The sample is then studied to determine the cause of kidney issues and guide appropriate treatment. Renal biopsies are generally safe but may have minor risks like bleeding or soreness afterward.
