This study was conducted to explore the diagnosis and management of urothelial carcinoma of the prostate in superficial disease and carcinoma in situ, stromal invasion, primary urothelial carcinoma, and urethral recurrence after radical surgery. A consensus conference convened by the World Health Organization (WHO) and the Société Internationale d’Urologie (SIU) reviewed the diagnosis and management of urothelial carcinoma of the bladder. English-language literature about urothelial carcinoma of the prostate was identified and reviewed. Evidence-based recommendations for the diagnosis and management of urothelial carcinoma were made. Many recommendations were level 3 or 4 citations involving the diagnosis and management of superficial urothelial carcinoma; a few were level 2 citations. Level 1 citations related only to chemotherapy and radiotherapy in patients with stromal invasion, although these were not related specifically to invasive prostatic involvement. More than 130 reviewed citations are summarized in this review. Published reports on the diagnosis and treatment of superficial urothelial disease of the prostate primarily consist of short case series from individual centers. Prospective and multicenter trials are needed to identify the real incidence and the best management of these patients. In invasive disease of the prostate, the only large series were designed to investigate invasive bladder cancer.
