Kidney abscess risk factors

The biggest risk factor for perirenal abscess is kidney stones that block the flow of urine and provide a place for an infection to grow. Bacteria tend to stick to the stones and antibiotics can’t kill the bacteria there.

Stones are found in 20 – 60% of patients with perirenal abscess. Other risk factors for perirenal abscess include:

• Diabetes
• Having an abnormal urinary tract
• Trauma
