[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.
