Ureteral intramural metastatic deposit of prostate cancer with ureteric obstruction

Ureteric obstruction secondary to unusual metastasis of prostate cancer

A case of ureteric metastasis secondary to prostate cancer. A 70-year-old man presented with a rising PSA five years post radical prostatectomy and salvage radiotherapy.

Conventional staging (CT/bone scan) was negative but a ⁶⁸Ga-PSMA-PET/CT scan and ureteroscopy later confirmed a ureteric metastasis. This was treated with robotic-assisted radical nephroureterectomy.

What are the odds? Prostate metastases to ureter and peritoneum

In patients with prostate cancer, metastases mostly develop in bone, lung, liver, pleura and adrenal glands. Prostate carcinoma metastases to the ureter are very rare, and the peritoneum is an even rarer site of prostate metastases. We present two cases of ureteral metastases of prostate cancer, of which one patient also developed malignant ascites and peritoneal metastases. An overview of the literature on these metastatic sites is also provided. Both patients presented with hydronephrosis and a ureteral mass. Biopsies of the masses were taken, which showed the presence of prostate carcinoma metastases. The first patient was treated with chemotherapy but was diagnosed with progressive disease and died 3 years later. The second patient was diagnosed with pathology-confirmed peritoneal metastases 8 months later. He died 2 years after presentation with hydronephrosis.
