title: [A case of ureteritis with a course of rapidly progressing stricture].
abstract: Rapidly progressing stricture of the ureter with non-specific ureteritis is very rare and neither pathogenesis nor reliable treatment is known. We report a case of ureteritis in a 51-year-old woman with a stricture rapidly progressing over a course of 2 months. She was sent to us for left hydronephrosis. Retrograde pyelography (RP) revealed a 5 cm stricture in the left ureter. CT showed no abnormal mass in the retroperitoneum. Gastro-intestinal and gynecological inspection revealed no abnormalities. As a second RP showed 9 cm stricture 2 months later, we performed a biopsy of the ureter and examined it pathologically. There was no evidence of malignancy, but we performed a left nephroureterectomy, because of the stricture in the entire left ureter. Pathological study of the kidney and the ureter showed a non-specific inflammation of the entire urothelium without malignancy. There has been no recurrence in the right ureter.
