[A case of a ureteral inflammatory pseudotumor].
The patient was a 28-year-old woman. In February 2002, she visited another physician due to acute pyelonephritis. Based on CT findings, a lower ureteral stricture caused by a benign extraureteral tumor was diagnosed. The patient was being monitored by periodic exchange of ureteral stents. In February 2003, the patient visited our department seeking a second opinion. Retrograde pyelography showed an elliptical filling defect in the lower urinary tract. Ureteroscopy showed that the surface of the tumor was mostly smooth, regular and partially papillary. Biopsy was performed, and histological analysis revealed only nonspecific inflammation. In December 2003, based on a diagnosis of benign ureteral tumor, we performed partial resection of the right urinary tract and ureterocystoneostomy. As rapid intraoperative pathological analysis confirmed an inflammatory pseudotumor, total nephroureterectomy was avoided.
