Therapeutic recommendations of the multidisciplinary group

There are specific indications in urological procedures [transurethral resection of the prostate (TURP), transurethral resection of the bladder (TURB), endoscopic procedures, and all interventions classified as contaminated or dirty] requiring antibiotic prophylaxis. Most postoperative infections are caused by enterococci of the Gram-positive strains and Enterobacteriaceae of the Gram-negative ones. As reported by the European Center for Disease Prevention and Control (ECDC), there are increasing numbers of antibiotic-resistant pathogens. Most Enterococcus faecium strains are ampicillin-resistant and the Enterobacteriaceae have a high prevalence of extended-spectrum beta-lactamase (ESBL) producers, for which the cephalosporins and penicillins are not drugs of choice. In recent years, there are also increasing numbers of Gram-negative strains that are able to produce carbapenemases and for which the only therapeutic options are gentamicin, tigecycline and colistin. An alternative to these drugs, from a prophylactic point of view, is fosfomycin, an old antibiotic that maintains bactericidal activity against both enterococci and multidrug-resistant Enterobacteriaceae. Available in an oral formulation as trometamol salt, fosfomycin reaches high plasma and urine concentrations, and is therefore a possible alternative to other drugs both for therapy and urological prophylaxis. In this paper there will be an update about antibiotic prophylaxis in urological procedures, considering also new antibiotic resistance patterns of uropathogens.
