title: [Bacteriological diagnosis of renal tuberculosis: an experience at the regional tuberculosis laboratory in Córdoba Province, Argentina].
abstract: Given the incidence of renal tuberculosis in patients suffering of pulmonary tuberculosis, we seek to study both the frequency of this association in diagnosed cases of renal tuberculosis and the Mycobacterium tuberculosis complex species that were identified (period 1997-2009), observing its incidence by sex, demonstrating the importance of serial culture of urine samples and evaluating the convenience of using solid and liquid media. The analysis of urine samples from 383 patients indicated renal tuberculosis in 24 cases; in most cases, (95.8 %) Mycobacterium tuberculosis complex species prevailed, whereas the presence of Mycobacterium bovis accounted for 4.2 % of the cases. The association of pulmonary and renal tuberculosis was found in 6 cases. The isolation of Mycobacterium bovis indicates the importance of including Stonebrink medium along with Lowenstein- Jensen medium. The liquid medium made no significant contribution to the diagnosis of renal tuberculosis, but indeed, cultivating serial samples increases sensitivity.
