The cost of treating pleural effusion varies depending mainly on the nature of the pleural effusion. Generally the pleural effusion caused by infection can be cured with 5000-6000 dollars. If the pleural effusion is caused by tuberculous pleurisy, it needs to be hospitalized for one month, which will cost about 10,000 yuan, and in the later stage, it also needs to continue anti-TB treatment and take anti-TB drugs orally for one year, and these costs are about 1,000-2,000 yuan. For malignant pleural effusion, the cost is higher, because of the need to replenish albumin, nutrition, and the need to give sensitizing chemotherapy, so the cost is higher, sometimes$30,000.
