A Case of Bilateral Xanthogranulomatous Pyelonephritis with Renal Failure / 대한신장학회지

ABSTRACT

Xanthogranlomatous pyelonephritis is a rare chronic inflammatory renal disease. Its clinical and radiological findings resemble other renal parenchymal diseases, such as a renal abscess or renal cell carcinoma. Only a histologic examination can confirm xanthogranulomatous pyelonephritis. It usually presents unilaterally and displays relatively normal renal function. Bilateral xanthogranulomatous pyelonephritis is extremely rare. The renal function of bilateral xanthogranulomatous pyelonephritis is usually normal at the time of diagnosis, but progresses to end stage renal failure as the disease progresses. We experienced a case of bilateral xanthogranulomatous pyelonephritis, and its initial manifestation was renal failure. We report this case with a review of the literatures.
