causes of kidney abscess
A renal abscess can be caused by bacteria from an infection thatâs gotten to the kidneys. The bacteria can travel through the blood or in urine backing up into the kidney. In the kidney, the bacteria can spread to the kidney tissue. A renal abscess is not a common disease. It often occurs as a result of common problems such as: Kidney inflammation. Stone disease. Urine flowing backwards into the kidney from the bladder (âvesicoureteral refluxâ)
