CABALLERO ROMEU, Juan P. et al. Primary adenocarcinoma of a ureteral remnant stump after nephrectomy. []. , 33, 6, pp.691-695. ISSN 0210-4806.

Aim: Adenocarcinomas of the upper urinary tract are very rare malignancies often related to primary genitourinary and extraurinary tumours. Primary adenocarcinomas are even rarer. There are no clinical guidelines for the management of primary ureteral adenocarcinoma. Our objective is to propose a clinical management of this sort of tumours. Methods: We report a case of adenocarcinoma affecting a ureteral stump in a patient who previously underwent a nephrectomy. A review of literature is performed. Results: After the ureterectomy the pathologist diagnosed a ureteral adenocarcinoma. We perform an extension study which discards an extraurinary origin. Conclusions: Adenocarcinoma of the ureteral stump is a very rare malignancy. About the clinic and pathologic characterization, there is no an established reference due to the short number of previous reports. Clinical presentation may include previous nephrectomy, flank pain, dysuria, urgency and/or gross hematuria. It seem necessary the complete resection of the urinary tract when a nephrectomy is performed. Adjuvant chemotherapy can be employed with uncertain results.
