Ureteric stricture: an unusual presentation of metastatic prostate adenocarcinoma

摘要

We describe an unusual case of a prostatic adenocarcinoma presenting with a ureteric stricture secondary to a discrete metastatic lesion. A 76-year-old man presented with a short history of right loin pain. Initial examination was unremarkable, digital rectal examination was normal and prostate specific antigen was within normal range. Computed tomography showed right hydronephrosis and a distal ureteric stricture. A distal ureteric transitional cell carcinoma was thought to be most likely. A nephroureterectomy was carried out and histology revealed a skipped lesion of a metastatic prostate adenocarcinoma. Metastatic lesions to the ureters due to prostate cancer are rare. It was believed to be secondary to a transitional cell carcinoma as there was no evidence initially to suggest prostatic disease as the cause. A prostatic adenocarcinoma should be considered in the differential diagnosis of any lesions in the ureter believed to have a malignant origin.
