Metastatic prostate cancer has poor prognosis, with survival rates ranging from 1 to 3 years. Frequent sites for metastases are the skeletal system and lymph nodes; metastases to the gastrointestinal tract are rare. Although most patients become symptomatic with bone or flank pain, the patient we report initially presented with severe nausea and vomiting accompanied by moderate back pain. His prostate-specific antigen level was 171 ng/mL. Computed tomography and bone scan revealed retroperitoneal lymphadenopathy and bone metastasis. Cranial computed tomography was negative for metastasis but upper endoscopy and biopsy revealed a metastatic lesion from prostate cancer.

Prostate cancer is one of the most common male malignancies, but it rarely metastasizes to the proximal ureter. We report a case of a 76-year-old man who presented with flank pain and lower urinary tract symptoms. Abdominal computed tomography scan revealed multiple filling defects at the middle of the left ureter, enlarged retroperitoneal lymph nodes, and probable psoas invasion. The patient underwent nephroureterectomy with excision of a cuff of bladder, and was found to have an adhesion between the middle part of left ureter and psoas intraoperatively. The pathological examination displayed positive immunohistochemical staining with prostate-specific antigen and prostate acid phostate, supporting the diagnosis of metastatic ureteral tumour from prostate cancer. In this case, periureteral soft tissue and ureteral muscular layer were infiltrated by metastatic tumour, whereas the mucosa was spared. The periureteral lymphatic pathway played an important role in the metastatic procedure of prostate cancer to the proximal ureter.
