title: Xanthogranulomatous pyelonephritis: experience in 36 cases.
abstract: A retrospective study of 36 patients with xanthogranulomatous pyelonephritis who underwent nephrectomy at our hospital was performed. The disease occurred most frequently in middle-aged women with a history of recurrent urinary tract disorder. There were 2 cases of focal xanthogranulomatous pyelonephritis, 2 associated with emphysematous pyelonephritis, 2 that manifested as fistula formation between the colon or skin, and 1 with deep sinus formation into the hip joint that presented as septic arthritis. Flank pain and fever were the most frequent complaints. Escherichia coli (67%) and Proteus mirabilis (26%) were the most common organisms isolated from the voided urine, kidney and blood stream. Cephalothin plus gentamicin or tobramycin were the drugs of choice before surgical intervention.
