Kidney puncture is a test for kidney cancer that can better determine if you have it. However, there are many risks associated with kidney puncture, which may damage large blood vessels and may lead to cancer cell implantation, so it is best not to have a kidney puncture.
Kidney puncture is often mentioned in medicine as a puncture to confirm the presence of cancer cells, but it is actually quite dangerous and many doctors do not recommend it.
First of all, a kidney puncture may injure a nearby large vein or artery. The large veins and arteries that pass through the kidney are relatively thick, and if the puncture is done incorrectly, it is easy to injure the blood vessels, which will certainly bleed.
Kidney punctures can also lead to healthy areas where cancer cells are implanted. When a kidney is punctured, the puncture needle may pass through the cancer cells and plant them in a healthy area with it, which can turn an early stage cancer into a more serious, advanced cancer. Although the probability is not very high, such a danger does exist.
Because of these risks, doctors usually do not recommend kidney puncture, and other tests, such as ultrasound, Ct, MRI, or PET-CT, can be useful.
