Abscess of prostate has become a rare disease due to development of modern antibiotics and decreasing incidence of gonococcal infection. Recently the pathogen of prostatic abscess is almostly E. coli, the others are pseudomonas, staphylococcus, obligate anaerobic bacteria. Staphylococcus aureus infected rostatic abscess arises from other inflammatory focus as a complication of a skin infection by hematogenous route most commonly. We encountered two cases of Staphylococcus aureus infected prostatic abscess in diabetes mellitus patients. There had been no primary inflammatory focus in both cases moreover no fever in the first case. He did not complain of specific symptoms of prostatic abscess such as fever, dysuria, pyuria and perineal pain. The other one complained of fever and acute urinary retention. In both cases, prostatic abscess was suspected by transrectal ultrasonography and confirmed by percutaneous needle aspiration. The patients were treated with pathogen sensitive antibiotics combined with transurethral resection drainage of prostate.
