Summary
Xanthogranulomatous pyelonephritis (XGP) is a rare chronic kidney infection that mimics renal cancer. Diagnosis requires pathological study after surgical removal, and XGP should be considered in renal cancer differential diagnoses.
Area of Science:
- Nephrology
- Urology
- Pathology
Background:
- Xanthogranulomatous pyelonephritis (XGP) is an uncommon chronic renal infection.
- XGP can present with symptoms mimicking malignant renal neoplasms.
- Definitive diagnosis of XGP is typically established post-pathological examination following surgical intervention.
Purpose of the Study:
- To analyze the clinical, radiological, and surgical characteristics of XGP cases.
- To compare the findings with existing literature on XGP.
- To highlight the importance of considering XGP in the differential diagnosis of renal masses.
Main Methods:
- Retrospective study of 11 XGP cases diagnosed between 1945 and 2000.
- Analysis of clinical, radiological, and surgical data from medical records.
- Comparison of collected data with published literature.
Main Results:
- 82% of patients were female; 73% presented with pain and abdominal mass, hematuria, and fever.
- Radiological findings included renal parenchyma destruction, collecting system abnormalities, and lithiasis.
- Positive urine cultures (91%) were common, with Escherichia coli, Proteus Mirabilis, and Klebsiella being the most frequent pathogens.
Conclusions:
- Xanthogranulomatous pyelonephritis shares clinical features with renal cancer.
- XGP must be included in the differential diagnosis of patients presenting with suspected renal malignancy.
- Simple nephrectomy was an effective treatment with minimal complications.
