Will a kidney biopsy leave scars?

A kidney biopsy usually leaves no scars.

Local anesthesia is required before needle biopsy. Under anesthesia, the puncture needle is guided into the kidney through the skin by ultrasound, and then a very small amount of kidney tissue is removed. The puncture needle is relatively thin, so there is usually no scarring. Renal puncture is an invasive operation. After renal puncture, it is very important for patient care. Absolute bed rest is required for 24 hours, and changes in vital signs need to be closely observed to avoid complications such as bleeding and infection.

At present, the technology of renal biopsy is very mature, and the probability of complications is relatively low. The main purpose of renal biopsy is to identify the pathological type of renal disease, guide treatment and judge prognosis. It is the gold standard for diagnosing renal disease.
