A renal abscess is caused by urinary tract infections that start in the bladder. Then they spread to the kidneys and then to the area around them.

Surgery in the urinary tract or reproductive system, or an infection of the bloodstream, can also lead to a kidney abscess.

Kidney stones are the biggest risk factor for kidney abscess, which block the urinary flow. This favors the proliferation of the infection. Bacteria tend to stick to the stones and antibiotics can not destroy them there.
