Ureteral metastasis from locally invasive, castrate-resistant prostate cancer: A Case report.

Abstract Within the text we describe a 66-year-old male with a history of prostate cancer (PCa), incidentally found to have left-sided hydronephrosis and a left ureteral lesion. Ureteroscopy was employed to visualize the lesion, a biopsy was taken, and a double J stent was placed. The lesion was of prostatic origin and the patient was subsequently started on androgen deprivation therapy (ADT). 6 months following the procedure, the patient's PSA had decreased and his hydronephrosis had resolved. We are the first to report treating a ureteral metastasis from PCa and its associated hydronephrosis solely with ADT and double J stenting, respectively.
