El hallazgo de especies de Candida en la orina es un hallazgo habitual y se denomina candiduria. Hay un aumento en la frecuencia de infecciones del tracto urinario (ITU) causadas por Candida, especialmente en pacientes críticamente enfermos. Este estudio tuvo como objetivo determinar las características epidemiológicas, clínicas y micológicas de las infecciones urinarias por Candida en la unidad de cuidados intensivos (UCI) y la susceptibilidad antifúngica. Métodos: Se evaluaron urocultivos de 394 pacientes de UCI con sospecha clínica de ITU. Después de 24-48 horas de incubación, las colonias parecían crecer como levadura, se examinaron morfológicamente mediante tinción de Gram. Las cepas de Candida que crecieron 104 ≥ UFC / ml en urocultivos se aceptaron como candiduria. Las susceptibilidades de las cepas de Candida a la anfotericina B, itraconazol, fluconazol, voriconazol, flucitosina y caspofungina se investigaron con el método de microdilución en caldo. Resultados: La distribución de las cepas 100 urinarias aisladas de Candida fue de, 54 C. albicans, 34 C. glabrata, 7 C. tropicalis, 2 C. kefyr, 2 C. lusitaniae y 1 como C. parapsilosis. Entre las 100 especies de Candida aisladas en nuestro estudio, las tasas de susceptibilidad de anfotericina B, flucitosina, caspofungina, fluconazol, itraconazol y voriconazol fueron 100%, 100%, 91%, 23%, 13%, 25,8%, respectivamente. Conclusión: La identificación precisa de Candida spp., así como la investigación de la susceptibilidad antifúngica, será beneficiosa en términos de la eficacia del tratamiento y la prevención del desarrollo de resistencias.
