Xanthogranulomatous Pyelonephritis
Xanthogranulomatous pyelonephritis is a severe, chronic kidney infection that can destroy kidney tissue over time.
When to get help quickly: Prompt hospital care is important if there is fever, severe flank pain, weakness, vomiting, confusion, or signs of sepsis in someone with suspected kidney infection.
Common symptoms
Symptoms may include fever, flank pain, tiredness, weight loss, repeated urinary infection, a kidney-area swelling, or generally feeling unwell for a long time.
When imaging helps
Imaging helps show whether the kidney is enlarged, damaged, obstructed by stones, or surrounded by infection and helps plan treatment.
What radiology does
CT is especially useful because it can show stones, obstruction, kidney enlargement, and the destructive inflammatory pattern.
What usually happens next
Treatment often involves antibiotics and, in advanced cases, surgery because the kidney may be badly damaged.
