[Ureteritis glandularis: a case report].

Abstract

A 50-year-old Japanese male hospitalized with the complaint of fever and pyohematuria. An excretory pyelography revealed the right hydronephroureter due to right ureteral stone. When the ureterolithotomy was carried out, a wide-based and rice-sized tumor co-existed at the site of the epithelium of the ureter lithotomized. Resected tumor was pathologically confirmed as poorly differentiated adenocarcinoma with mitosis. Therefore, total nephroureterectomy with bladder cuff resection was done at 10 days after the first operation. However, malignant cells were not found in the surgical specimen or histologically diagnosed localized glandular ureteritis. He is alive without any evidence of recurrence. It was reported that the glandular metaplasia, a relative rare lesion in the ureter, was correlated with carcinogenesis of adenocarcinoma in urothelium. However, when the lesion is small and localized such as in this case it should be treated with ureterectomy and addition of other suitable adjuvant therapies. Furthermore, endourological techniques which have been recently dramatically progressed may become a weapon against this lesion for both treatment and follow-up.
