[Nosocomial infections in an urological department. Incidence and etiological factors]

Abstract

The authors report a prospective study with active request of data for nosocomial infections (NI) in an urological department during six months. From 453 patients, 43 developed an NI (incidence = 9.5%): urinary tract infections (53.5%), bloodstream infections (16.3%), lower respiratory tract infections (7%), surgical wound infections (2.3%) and sepsis syndrome (20.9%). For microorganisms, most often Pseudomonas aeruginosa (22.5%) and E. coli (20%) were encountered. Other microorganisms were the next-ones: Staphylococcus aureus (15%), Staphylococcus epidermidis (7.5%), Acinetobacter baumanii (7.5%), Streptococcus group D (7.5%), Klebsiella pneumoniae (7.5%), Candida albicans (2.5%) and others (10%). Urological interventions with a high risk of NI were cystectomy with intestinal urinary diversion (68.7%), pyeloplasty for ureteropelvic junction obstruction (40%) and percutaneous nephrolitothomy (30%). Even if the last two interventions classically do not have a high risk of NI, we think that their antibioprophylaxis is recommended.
