Urinary tract infection (UTI) is one of the most common bacterial infections, affecting up to 150 million people worldwide, and certain host conditions predispose urinary tract infection to be considered complicated and therefore warrant broad-spectrum empirical treatment, in the elderly, complicated urinary tract infection should always be considered within the range of diagnoses, as the symptoms and signs for which they consult the emergency department are often very nonspecific, although this leads to overdiagnosis and overtreatment of this condition. Should not be limited to suspicion, especially if the patient has clinical conditions that assert the risk of a complicated UTI, as happened in the case of our index patient: An 83 year old adult with a history of Alzheimer's disease and urinary incontinence, admitted because he showed fever of 2 days of evolution and foul-smelling urine. A urine sample was taken for urinalysis which was suggestive of urinary tract infection and a urine culture showed infection by Citrobacter koserii. Knowing the susceptibility profile, it was decided to rotate to ciprofloxacin and continued new antibiotic treatment until completing 10 days counting as effective the days in which he received Piperacillin/tazobactam, presenting good evolution until medical discharge.
