In a world where there is a variety of drugs used to treat a wide variety of diseases; there is a very special group, which helps us to fight those pathologies caused by bacteria -whether they are Gram-positive or negative- receiving the name of antibacterials or antibiotics. These are little by little losing their effectiveness through bacterial mechanisms that reduce their susceptibility to different microorganisms, which may be influenced by different factors. Thus the objective of this study is to compare the profile of antimicrobial susceptibility of Gram-negative uropathogens by age and sex in the National Hospital Alberto Sabogal Sologuren in the period 2015 - 2017. For this case series study was carried out, evaluating 6584 urocultures of patients with outpatient care, determining the most frequent Gramnegative uropathogens and antimicrobial susceptibility according to year, sex and age (<65 years and ≥65 years). 71% of the isolates were E. coli, followed in a smaller proportion by Klebsiella pneumoniae (11.3%), Pseudomonas aeruginosa (4.3%), Proteus mirabilis (3.3%) and other Gramnegative (10.1%). Which, except P. aeruginosa, showed a greater susceptibility of 90% for amikacin (93-99%), gentamicin (75-83%), ceftazidime (94-100%), ceftriaxone (96-99%), ertapenem (100%), piperacillin / tazobactam (88-100%) and tigecycline (96-100%), while levofloxacin was less than 80% (23-80%), without significant variation (p> 0.05) related to each year; P. aeruginosa showed a decreased susceptibility to piperacillin/tazobactam (7079%), being less than 50% for the rest of antibiotics. In addition, it was observed that the female gender has a greater susceptibilit y to gentamicin (Δ = 10-20%, p <0.05) for E. coli and K. pneumoniae and with ceftazidime (Δ = 28%, p <0.05) for P. aeruginosa; but with the rest of antibiotics there was no difference (p> 0.05). Similarly, in people under 65 gentamicin had better susceptibilit y (Δ = 6-20%, p> 0.05), without significant difference (p> 0.05) with the rest of antibiotics. It is established that E. coli is the most frequent uropathogen, susceptibility in the period of 3 years has not changed significantly and that the female sex and the age group younger than 65 have a better profile of antibiotic susceptibility.
