Objectives: Prostatic abscess (PA) is an infrequent condition in the modern antibiotic era. The everyday use of transrectal ultrasound (TRUS) during diagnostic work-up and the widespread recurrence to prostatic biopsies may lead to an increase of PA diagnosis. In this short report we analyze the patients characteristics and the management of seven recent cases of PA diagnosed in our institution. Materials and Methods: The records of 7 patients admitted to our Center for LUTS associated to septic fever or acute urinary retention, was prospectively collected. Suspect of PA was done on digital rectal examination (DRE) and confirmed by TRUS performed after urinary system ultrasound (UUS) evaluation. Patients were admitted to hospital only in case of septic signs. A sovrapubic (SPC) or urethral catheter (UC) was placed depending on symptoms. A TRUS-guided aspiration of PA was performed with patient in lithotomic position, using a 18 gauge two-part needle, side/end fire needle access. Patient was discharged with antibiotic therapy and followed up until complete resolution of the PA and symptoms. Results: Mean age was 62 years (range 24-82). Two patients were diabetics and one was affected by the immunodeficiency acquired syndrome (HIV). In one case, PA was detected after a persistent fever post TRUS guided prostate biopsy. Average prostate volume was 69 ml (range 19-118 ml). DRE was able to diagnose PA only in 2 cases (29%), UUS evaluation in 1 case (14%). All cases were confirmed by TRUS as hypo-anechoic areas with or without internal echoes in all patients. Mean PA dimension was 3.64 cm (range 1.5-8). SPC was placed in 3 cases (43%), UC in 3 patients (43%). Only 1 patient refused catheterization. Side fire needle aspiration was performed in all cases and in combination with end fire access in case of particular location of abscess cavities. Second look was needed in 2 cases (29%). Antibiotics were administered in all cases. The aspirated pus showed a positive culture for Escherichia coli (43%), Klebsiella pneumoniae (29%), Pseudomonas aeruginosa (14%) and Enterococcus faecalis (14%). PA resolution time mean was 9 days (range 3-24). Conclusions: TRUS evaluation in case of persistent LUTS associated with fever or acute urinary retention is determinant in the diagnosis of PA. Office or institutional management with TRUS needle aspiration is a good option in these cases.
