Incidence and Predictors of Tracheobronchial Tuberculosis in Pulmonary Tuberculosis: A Multicentre, Large-Scale and Prospective Study in Southern China

Abstract

About 23.9% of PTB patients undergoing bronchoscopy present with TBTB in Guangdong province, southern China. Young and middle-aged females with symptoms persisting for ≥4 weeks (the main predictors of TBTB and related tracheobronchial stenosis) should receive bronchoscopy immediately when diagnosed with PTB.
