[Metachronous metastasis in ureteral stump secondary to ipsilateral renal adenocarcinoma].

OBJECTIVES

Ureteral metastasis from renal adenocarcinoma is uncommon. The rarity of this disease prompted us to report on the present case, with special reference to diagnosis.

METHODS/RESULTS: A patient with metachronous metastasis in the ureteral stump from clear cell renal adenocarcinoma resected three years earlier is described. The etiopathogenic, clinical, diagnostic and therapeutic aspects are briefly reviewed.

CONCLUSIONS

Ureteral metastases, although uncommon, are generally ipsilateral to the renal tumor and arise from aggressive renal carcinomas that are locally advanced with vascular and/or lymphatic spread. We underscore the importance of retrograde pyelography and ureterorenoscopy in the diagnostic workup of all patients with gross hematuria following nephrectomy due to hypernephroma.
