The sample obtained is processed by the Pathological Anatomy Department for observation using optical microscope, fluorescence microscope and electronic microscope techniques. This enables different parts of the kidney to be observed: the glomerulus, the tubule, and the blood vessels. Special liquids can also be used to reveal infections and toxicity produced by different medicines.
This is very useful both for diagnosing disease in the kidneys themselves, as well as a test to monitor a kidney transplant.
Although a kidney biopsy is not without complications worth mentioning, they occur rarely and can be resolved. Urine may contain blood, for example, although this generally stops by itself. Renal haematoma may also occur, which also does not require treatment. Accidental communication between an artery and a vein may also occur, which can be repaired via catheterization to close the anomalous communication.
Kidney biopsy is a common procedure in the Nephrology Department and complications occur in around 1-2% of cases, which are subsequently resolved. It is therefore considered a safe routine procedure.
