Abstract (EN): OBJECTIVE To evaluate the clinical profile and the organisms producing adjustable transobturator male system (ATOMS) infection in a contemporary series. METHODS Multicenter retrospective study evaluating patients undergoing ATOMS explant for clinical signs of infection from a series of 902 patients treated in 9 academic institutions. Clinical and microbiological data were evaluated. RESULTS Infection presented in 24 patients (2.7%). The median age was 73 +/- 7yrs and the median interval from ATOMS implantation to explant 11 +/- 26.5mo. Infection was diagnosed within 3-months after surgery in 7(29.2%). Scrotal port erosion was present in 6 cases (25%) and systemic symptoms of parenchymatous testicular infection in 2(8.3%). The culture of the periprosthetic fluid was positive in 20(83.3%): 12(50%) Gram-negative bacteria, 9(37.5%) Gram-positive cocci and 1(4.2%) yeast. The most frequent isolates were Enterococcus and Proteus sp. (16.7% each), followed by Pseudomona sp. and S. epidermidis (12.5% each). Methicillin resistant S. aureus was detected only in 1 case (4.2%). Despite the infection 17 patients (70.8%) were satisfied with the implant and 18(75%) received a second device (11 repeated ATOMS and 7 AUS) at a median 9.7 +/- 12.6mo after explant. Limitations include retrospective design and lack of microbiological cultures in ATOMS explanted for non-infective cause. CONCLUSION Infection of a prosthetic device is a disturbing complication. A proportion of patients with ATOMS infection is associated to scrotal port erosion and/or parenchymatous urinary tract infection. Enterococcus and Proteus sp. are the most common organisms producing ATOMS infection and this could have implications for the selection of the most appropriate surgical prophylaxis.
