Focal prostatic granulomas. A sequel to transurethral resection.

Clinical and histologic findings in 6 cases of prostatic granuloma following transurethral prostatic resection are described. The repeat operations were performed 1 week to 14 months after the initial resection because of severe micturition urgency, voiding difficulty or persistent haematuria. Bacteriuria did not seem to be of aetiologic importance for the granulomas. In all cases the granulomas contained areas of fibrinoid necrosis, and in three cases the granulomas were surrounded by eosinophilic infiltrates. The condition is not widely recognized by pathologists, which was illustrated by the initial diagnosis of specific inflammation consistent with tuberculosis in three patients. Though the disorder seems to be self-limiting, its association with persistent haematuria after transurethral prostatic resection is noteworthy.
