[Primary adenocarcinoma of a ureteral remnant stump after nephrectomy].

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 management algoritm 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 performed an extension study in order to discard 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.
