Prostate cancer metastasis to the ureter is extremely rare because only 45 such cases have been reported worldwide in the last century. It accounts for 30% of ureteral metastasis. Neuroendocrine differentiation is approximately 1% of the entire primary prostate adenocarcinoma pathology. Metastatic prostate cancer may pose as upper tract urothelial carcinoma. Prostate may look normal on clinic-radiological examination in prostate cancer. Majority of such cases are managed with nephroureterectomy. Herein, we report a case of 62-year gentleman, who presented with refractory left flank pain with repeated imaging suggestive of neoplastic left ureteric stricture and normal prostate on clinic-radiological examinations. The case was later found with the diagnosis of metastatic prostate adenocarcinoma with neuroendocrine differentiation after left sided nephroureterectomy done for a provisional diagnosis of Upper Tract Urothelial Carcinoma (UTUC).
