Xanthogranulomatous pyelonephritis: a report of eleven cases and review of literature

ABSTRACT

A retrospective study of 11 patients with Xanthogranulomatous pyelonephritis who underwent nephrectomy at the hospital was done. Intravenous urography [IVU] and ultrasonography [US] were done in all cases while CT was done in 5 cases. Right kidney was dominantly affected [7 cases]. One case manifested as a right flank sinus. 2 cases had focal Xanthogranulomatous pyelonephritis and one of them was a 3-year old female child. Associated stones were found in 10 cases while ureteric stenosis was documented in 4 cases. Flank pain was the commonest complaint [81.8%]. Escherichia coli [54.4%] and Proteus mirabilis [18.2%] were the most common organisms isolated from the voided urine. The findings are demonstrated and compared to those in literature
