Does kidney puncture damage the kidneys?

Renal puncture has certain damage to the kidney. Renal puncture is the extraction of renal tissue through a needle biopsy. Since the kidney is a capillary glomerulus, blood vessels may be damaged during the puncture process, resulting in bleeding. After puncture, the incidence of microscopic hematuria is high, but most of them disappear on their own. There are also some patients with gross hematuria, which can be gradually relieved after 1-3 days. Patients with severe bleeding need to be given symptomatic treatment such as blood transfusion and fluid replacement.

Some patients develop perirenal hematoma after puncture, most of which are small hematomas with no clinical symptoms and can be absorbed by themselves, and some have larger hematomas. Rehydration and blood transfusion treatment is required, and anti-infective drugs are used to prevent infection. In addition, some patients have arteriovenous fistula after puncture, and most of them can be relieved spontaneously.
