Abstract: Objective To explore the value of transbronchial needle aspiration (TBNA) in diagnosing the bronchial tuberculosis.Methods TBNA biopsy was performed in 36 cases of patients with the bronchial tuberculosis (BT),the Results were compared with those of brushing and operational specimens for cytological examination.Results The Results showed the correct diagnosis rate was 83.3% (30/36) for TBNA,44.4% (16/36) for brushing and 55.6% (10/18) for operational specimens and cytological examination.Of 21 cases BT,the early diagnosis was 90.5% (19/21) for TBNA and 28.6% (6/21) for brushing.There was significantlly different in them (P＜0.005 ).Conclusion TBNA could help enhance the correct diagnosis rate in BT,especially for the old patients.
