title: [Renal stone ileus in xanthogranulomatous pyelonephritis. A case report].
abstract: A peculiar case of intestinal occlusion caused by a renal stone in a patient with nephroduodenal fistula due to previous xanthogranulomatous pyelonephritis is reported. Only few cases of nephroduodenal fistula are described in the literature, generally as a single case report or in small series. A nephroduodenal fistula as a result of chronic renal inflammatory disease such as xanthogranulomatous pyelonephritis, is usually associated with renal stones, recurrent urinary tract infections or endocrine disorders. Finally, renal stone as a cause of ileus is an event rarely described in the literature. In the case described, a correct preoperative diagnosis was possible with computerized tomography. During the operation a big renal stone was found and removed from the small bowel, but a limited resection was necessary because of the vascular impairment of the tract. At 8-month follow-up from operation, the patient was in good health, and no symptoms of renal or intestinal diseases were found.
