    Abstract:
    OBJECTIVES: Our retrospective study aimed to analyze the findings and therapeutic strategies in 18 men who were admitted to our department as outpatient emergency cases with prostatic abscess. METHODS: During the period 1985 to 1997, prostatic abscess was diagnosed in 18 patients (mean age 48 years, range 20 to 68) on the basis of evidence of fluctuation at digital rectal examination and transrectal ultrasound (TRUS) findings. Diagnostic workup included analysis of midstream urine and abscess fluid for leukocytes and pathogens. Therapeutic options were conservative treatment and/or draining procedures. RESULTS: Predisposing diseases were found in 13 men. Fluctuation at digitorectal palpation was present in 15 patients. In 3 patients, diagnosis was based on TRUS. All men demonstrated leukocytes in their midstream urine. Causative pathogens in midstream urine were found in 11 patients. In 3 men, additional microbiologic evaluation of abscess fluid revealed uncommon pathogens. All patients received antibiotic treatment. Nine men with monofocal abscess less than 1 cm in diameter were treated with antibiotic therapy and a suprapubic catheter. Surgical drainage (transperineal or transrectal puncture, partly guided by TRUS, or transurethral unroofing) was performed in 12 patients and included 3 patients in whom conservative treatment failed. CONCLUSIONS: Our data confirm the importance of predisposing factors in the pathogenesis of prostatic abscess. Medical history and analysis of midstream urine indicated a diagnosis that was confirmed by digital palpation. In some cases, TRUS may improve diagnosis and treatment. Although both operative and conservative therapy strategies appear feasible, prostatic abscess chiefly requires individually selected drainage procedures.
