What is renal biopsy

Kidney biopsy is to take out a piece of kidney tissue through a kidney needle under local anesthesia, generally 2mm in diameter and 1.5-2.0cm in length. Examining the kidney tissue through a microscope can identify the pathological type of kidney disease, which is very useful for guiding treatment. Meaning, at present, renal puncture is performed under the guidance of color Doppler ultrasound, and the risk is very small. It is a routine examination in nephrology. Its indications are mainly for nephrotic syndrome, acute renal failure and kidney damage with a 24-hour urine protein quantification greater than 1 g.
