title: [Xanthogranulomatous pyelonephritis coexisting with fistula between ureter and sigmoid colon: a case report].
abstract: A 63-year-old woman with the complaints of left renal stone and fistula between left ureter and colon was transferred to our clinic by a local doctor. Anemia, gamma-globulinemia, and acceleration of ESR were detected by hematology on admission. Kidney-ureter-bladder X-ray and intravenous pyelography showed left non-functioning kidney with coral stone, and RP revealed a fistula between left ureter and sigmoid colon. She was operated by nephroureterectomy and fistulectomy. The resected kidney appeared pale and parenchyma was almost replaced by yellowish tissue and pus. Histologically, the lesion was confirmed to be xanthogranulomatous pyelonephritis. Meanwhile, the cause of the fistula was considered to be due to extending ureteritis and pelvic infection from the pyelonephritis. Postoperative course was satisfactory.
