SENSIBILIDAD Y ESPECIFICIDAD DEL EXAMEN GENERAL DE ORINA COMO PRUEBA DE ESCRUTINIO PARA INFECCIÓN DE VIAS URINARIAS EN PACIENTES CON DIABETES MELLITUS SIN SÍNTOMAS URINARIOS.

Abstract

INTRODUCTION.- Urinary tract Infection (UTI) is defined as the presence and multiplication of microorganisms in the genitourinary system and may or may not exist symptoms. Every year there are approximately 150 million visits associated to urinary symptoms. The risk of acquiring a complicated UTI in patients with Diabetes Mellitus (DM) is twice as high in relation to general population. Urinalysis provides information for the detection of urinary infection by chemical and microscopic analysis of urine. OBJECTIVE.- To determine the usefulness of urinalysis as screening test for UTI in diabetic patients without urinary symptoms. MATERIAL AND METHODS.- Observational, prospective, transversal and analytical study. 114 diabetic patients without clinical evidence of urinary infection were included. A midstream urine sample was requested and UGA as well as urine culture were developed. Data were analyzed by descriptive and inferential statistics in contingency 2x2 arrays. RESULTS.- UTI was confirmed in 41 cases (35.9%) with a sensitivity-specificity to leukocyte esterase (LE), nitrites, leucocytes and bacteria analysis of 84.6%-93.3%, 43.9%- 97.2%, 37.2%-83.3% and 93.6%-91% respectively. CONCLUSION.- The bacteriuria analysis showed the best sensitivity and specificity to early diagnosis of IVU in diabetic patients without symptoms, and a routinely urinalysis in this patients population is recommended
