Ureteral Metastasis From Prostate Cancer: A Report of Two Cases.

Prostate adenocarcinoma (PCa) is the second most common cause of cancer in men, but metastases to the ureter are exceedingly rare. Here, we present two cases with differing clinical symptoms and treatment courses but ultimately the same diagnosis. The two cases presented here had differing clinical presentations: one with lower urinary tract symptoms and the other with hydronephrosis. Systemic therapy with a luteinizing hormone-releasing hormone (LHrH) agonist appears to help with clinical outcomes in both cases reported here. Although such cases are extremely rare, consideration as a differential and early detection can impact a patient's clinical outcomes. For patients with PCa that present with obstructive urinary symptoms, there may be a clinical benefit to perform a thorough metastatic work-up for seeding to other parts of the urinary tract.
