Xanthogranulomatous pyelonephritis: a reappraisal
Lancet (London, England)
|June 19, 1982
Summary
Xanthogranulomatous pyelonephritis (XPN) is a progressive kidney inflammation often caused by urinary tract obstruction. Early diagnosis via imaging and prompt nephrectomy offer a curative solution for this condition.
Area of Science:
- Nephrology
- Pathology
- Radiology
Background:
- Xanthogranulomatous pyelonephritis (XPN) is a rare, destructive inflammatory kidney condition.
- It is characterized by lipid-laden foam cells and chronic renal inflammation, often linked to calculous urinary tract obstruction.
Purpose of the Study:
- To survey the clinical, radiological, ultrasonic, and pathological features of xanthogranulomatous pyelonephritis.
- To improve preoperative diagnosis and understanding of XPN.
Main Methods:
- Retrospective analysis of 80 patients diagnosed with XPN.
- Review of clinical presentations, radiological imaging (including ultrasonography), and pathological findings.
Main Results:
- XPN typically affects middle-aged females presenting with toxemia, loin mass, and urinary symptoms.
- Radiology and ultrasonography are key in preoperative diagnosis.
- Pathology reveals foam cells and inflammatory destruction of renal tissue.
Conclusions:
- Xanthogranulomatous pyelonephritis is more common than previously thought.
- Preoperative diagnosis is feasible with characteristic clinical and imaging findings.
- Nephrectomy is a curative treatment for XPN.
