Abstract:
Urothelial carcinoma of the bladder remains a challenging disease to treat. Intravesical instillation of BCG has demonstrated tremendous efficacy in preventing recurrence. BCG related necrotizing granulomatous epididymo-orchitis is rare and has not been previously linked to brachytherapy for adenocarcinoma of the prostate. We hypothesize that prior brachytherapy has a deleterious effect on the verumontanum that can result in retrograde transmission of BCG particles leading to granulomatous epididymo-orchitis. This is the first case report of necrotizing granulomatous epididymo-orchitis related to BCG in a patient status post brachytherapy for adenocarcinoma of the prostate.
