Abstract: Objective To further investigate the clinical character of tuberculous pleurisy (TP) and the relationship between tuberculous pleurisy and pulmonary tuberculosis.Methods The clinical status of 345 patients with tuberculous pleurisy were retrospectively analyzed.Results ①The age distribution in 345 patients was 51.6% for patients below 35,23.2% over 55. The average age of the overall patients was 38.1. ②Occurrence rate for fever, cough, chest pain was 73.6%, 57.7% and 51.9% respectively. ③Occurence rate for unilateral pleural effusion, bilateral pleural effusion, left and right lateral pleural effusion was 93.0%, 7.0%, 47.8% and 45.2% respectively. ④Moderate and mild pleural effusion was 94.5%, severe pleural effusion was only 5.5%. ⑤The patients with pleurisy occupied 16% for the overall. The patients of tuberculous pleurisy complicated with pulmonary tuberculosis were 47.8%. ⑥The patients with yellow pleural effusion was 89.6%. With bleeding pleural effusion was 10.4%. ⑦The positive rate of M.tuberculosis was 3.2% and 16.8% in pleural effusion and sputum. ⑧The positive rate in PPD reaction was 83.3%. ⑨The increasing ESR was 64.9%, and its mean value was 46.9mm/1h. Conclusion The tuberculous pleurisy was more often occurred in young people. It has close relationship with pulmonary tuberculosis. It is necessary to consider its clinical character in diagnosis.
