    Introduction: Extrapulmonary tuberculosis is an infection caused by Mycobacterium tuberculosis, which affects tissues and organs outside the lungs in 20-25% of tuberculosis cases. The objective was to determine the relationship between the results of bacilloscopy and Ogawa-Kudoh culture for the diagnosis of extrapulmonary tuberculosis. Methodology: In this correlational, retrospective, cross-sectional study, extrapulmonary samples were processed for microbiological diagnosis of TB. Four types of samples were included: gastric aspirate, stool, urine, and pleural fluid. Results: Out of 5,299 extrapulmonary samples, 3,700 (69.8%) were concordant and 161 (3%) were discordant. Diagnostic concordance analysis showed moderate agreement (κ=0.54, 95% CI 0.48 to 0.61) between both diagnostic tests for extrapulmonary tuberculosis. The frequency of positive results in the study samples was 245 (4.6%) for bacilloscopy and 239 (4.5%) for Ogawa-Kudoh culture, while the frequency of negative bacilloscopy results was 4,931 (93.1%), and 3,781 (71.4%) for the culture. Of the included samples, 278 (5.2%) had contaminated cultures. Conclusion: There is a relationship between the results of bacilloscopy and Ogawa-Kudoh culture methods in the diagnosis of tuberculosis at a general hospital in the El Agustino district, showing moderate concordance.
