What are the dangers of renal biopsy needle

As the current renal biopsy is generally performed under color Doppler ultrasound, the harm has been significantly reduced compared with before. Renal biopsy is a relatively safe clinical operation, so there is no need to worry too much. But from the theoretical and practical point of view, there is still a certain risk.

First of all, renal puncture is also an invasive puncture. Although the trauma is small, since the puncture needle needs to go directly to the renal parenchyma through the skin and subcutaneous tissue, pain and bleeding will be caused during this process. Some patients may experience allergies when using local anesthetics.

In addition, poor coordination during the puncture process may lead to tearing of the renal capsule. Subcutaneous hematoma may appear after puncture. In severe cases, there may be accidental injury to surrounding organs and blood vessels, as well as the possibility of massive hemorrhage and nephrectomy on the side of the kidney.
