[Prostatic abscesses: what treatment to propose?]

Microscopic abscesses of the prostate (< 1 cm) are usually treated by antibiotics with good prostatic diffusion, such as fluoroquinolones, for a minimum of 4 to 6 weeks. Complementary surgical drainage is generally required for larger abscesses or in case of an unfavourable course. The main points of discussion in the literature are the type of drainage and the incision that should be performed. Prostatic abscesses used to be drained via perineal incisions, but with a high mortality. The use of effective antibiotics has significantly improved the morbidity of prostatic abscesses. CT-guided percutaneous drainage (perineal or transrectal), or more frequently transrectal ultrasound-guided drainage, now allows rapid and effective evacuation of the abscess, without the need for general anaesthesia. The perineal route allows a simple J stent to be left in place for several days to ensure complete drainage, but it is not universally accepted. Transurethral exposure is indicated for periurethral prostatic abscesses.
