Resumo
As infecções urinárias são uma das principais causas de doença em Portugal, variando conforme sejam infecções urinárias
adquiridas na comunidade ou infecções urinárias nosocomiais.
Neste estudo determinou-se a prevalência dos microrganismos, presentes nas amostras de urina obtidas pela técnica
asséptica em doentes com infecções urinárias em ambulatório.Este estudo foi realizado no primeiro semestre do ano 2006,
utilizando os dados recolhidos num laboratório de Lisboa. Foi um estudo observacional, descritivo e transversal. Foram
incluídos todos os indivíduos que obtiveram um diagnóstico positivo na realização dos exames bacteriológicos
(urinoculturas).
Nos meses de Janeiro a Junho de 2006, primeiro semestre, foram realizadas 2820 urinoculturas, das quais 385 foram
positivas. Destas, 334 (86,75%) pertenciam a indivíduos do sexo feminino e 53 a indivíduos sexo masculino (13,25%).A
média de idades dos indivíduos foi de 55,25 anos (± 24,18 DP).
As bactérias responsáveis pelas infecções do tracto urinário com maior frequência foram a Escherichia coli (63,6 %),
Proteus spp.. (11,9 %), Enterococcus spp.. (7%) e Klebsiella spp.. (6%).
Deste estudo concluiu-se que as percentagens verificadas de agentes infecciosos, responsáveis pelas infecções urinárias
na comunidade, coincidem com padrões encontrados em estudos internacionais. Estas conclusões referem-se a um
laboratório de Lisboa, carecendo de estudos semelhantes ao nível nacional, para caracterização do fenómeno em Portugal.
The urinary infections are one of the main causes of disease in Portugal, varying as they are nosocomial infections or acquired in the community. In this study we intended to determine the prevalence of the micro-organisms, which causes urinary infections, obtained from the samples of aseptic urine. This study was accomplished in the first semester of 2006, using the data picked up in a Lisbon's laboratory. It's an observational, descriptive and cross study, including all the individuals that obtained a positive diagnosis in the accomplishment of the bacteriological exams (urine cultures) of a total of 2820 samples, in which 385 were positive, 334 (86,75%) belonging to females and 53 to male individuals (13,25%). The average of the ages was 55,25 years (± 24,18 SD). The higher frequency agents were Escherichia coli (63,6%), Proteus spp.. (11,9%), Enterococcus spp.. (7%) and Klebsiella spp.. (6%). This study lead to the conclusion that the general rate profile of infectious agents found as responsible for the urinary infections in the community within the data treated, is coincident with patterns found in international studies. The study herein reported is limited to a laboratory in Lisbon, being desirable for a further study either the characterization of this phenomena at national level, and also the additional collection of the correlated antibiotic susceptibility data for the identified ethiological agents.
