Objectives Our objective was to determine the utility of urine dipstick test for the screening of urinary tract infection in catheterized women following gynecological surgeries. Methods This was a descriptive study carried out in a tertiary care centre. Five hundred post-operative women were enrolled in the study whose urine samples were collected under sterile precautions from their catheters and simultaneously subjected to the dipstick test at the bed side of the patient and submitted to the laboratory for semi-quantitative culture and microscopy. Data were expressed as proportion. The results of the culture, microscopic examination, and the dipstick test were analyzed using Chi-square test. Results When culture results were compared with the leukocyte esterase (LE) test and the nitrite reduction (NR) test, the P value obtained was \0.0001, respectively. Sensitivity was 88.24, 85.29, and 87.88 %, respectively, for the LE test, NR test, and when both these tests were combined. The specificity for the LE test and the combination were, respectively, 98.46 % while for the NR test was 96.71 %. The positive predictive value decreased from 81.08 to 80.56 % on combining the tests while the negative value remained unchanged at 99.11 %. Conclusions These bedside tests could considerably reduce the laboratory workload and allow important clinical decisions to be made early.

“…Os problemas da próstata fazem com que a incidência volte a aumentar no sexo masculino logo após a 5ª e 6ª décadas de vida. Já no sexo feminino, passa a ser mais evidenciada no período que compreende da idade pré-escolar à fase adulta, onde nesta última, está associada com atividades sexuais, gestação e menopausa (ZAMAN, 1998).…”

RESUMOAs complicações e a gravidade da infecção do trato urinário determinam-se pela vulnerabilidade do paciente e pelas complexas interações entre o hospedeiro e o patógeno. O presente trabalho teve como objetivo mostrar a importância da análise do exame de urina tipo I, em 163 idosos do sexo masculino da cidade de Parnaíba -PI, bem como identificar possíveis achados que predispõem a ocorrência de ITU. Para análise comparativa foram confeccionadas tabelas, distribuindo os resultados em diferentes faixas etárias avaliando os aspectos físicos, químicos e de sedimento. Verificou-se que para a presença de nitrito 3,1% foram positivos. Para leucócitos e hemácias, quanto à característica incontáveis, foram encontrados 3,1% e 2,4% respectivamente, logo, foi necessário dar importância para variáveis com menor frequência, pois entende-se que uma pequena parcela a curto prazo pode representar uma grande quantidade de idosos ao decorrer do ano. É imprescindível ficar atento a prevalência de ITU, ao possível grau de suscetibilidade que pode ser apresentado e que mais estudos sejam realizados na área, tendo assim, um controle mais específico de qual faixa etária é a mais acometida.Palavras chave: Infecção; Epidemiologia; Urinálise; Saúde Pública. ABSTRACTThe severity of the urinary tract infection (UTI) and its resulting complications are determined by the patient's vulnerability and the complex interactions between the host and the pathogen. The aim of the present study was to show the importance of urine analysis -type I, in 163 elderly men from the city of Parnaíba, state of Piauí, as well as to identity possible findings that can predispose the occurrence of UTI. In order to make comparative analysis, the data were, distributed in different groups of age and the physical, chemical and sediment aspects were evaluated. It was observed that 3.1% of the 163 patients were positive to presence of nitrite. While 3.1% and 2.4% were positive to the presence of uncountable erythrocytes and leukocytes respectively. Thus, it was necessary to give importance to less frequent variables, once a small group of affected elderly patients might be related to higher numbers during the year. It is essential to be aware of the prevalence of UTI and the possible degree of susceptibility that can be presented. More studies are necessary, in order to have a more specific control of which age group is the most affected.Key words: Elderly men; Infections; Epidemiology; Urinalysis; Public Healthy. IntroduçãoA infecção do trato urinário (ITU) representa uma afecção frequente tanto em pacientes internados em hospitais, quanto na comunidade. Nos EUA a ITU é responsável por, em média, 8,3 milhões de visitas médicas por ano e está em segundo lugar no índice de infecções mais
