Abstract:ObjectiveTo investigate the clinical value of B ultrasound\|guided needle aspiration of the pleural effusion and intrapleural urokinase in the treatment of the parcel tuberculous pleural effusion.Methods327 cases of parcel tuberculous pleural effusion were divided into two groups from September 2008 to September 2010.143 cases were in the treatment group including 84 males and 59 females,mean age was 40 years,mean disease duration was 31 days;184 cases were in control group including 101 males,83 females,mean age was 45 years,mean disease duration was 33 days.All cases in the two groups were treated by strengthen the conventional anti\|tuberculosis,symptomatic and supportive of comprehensive treatment measures,and B ultrasound\|guided pleural fluid aspiration,urokinase were injected in treatment group after aspiration of pleural effusion;pleural effusion absorption and pleural thickness variation were observed in the two groups.ResultsIn the treatment group,pleural fluid drainage volume was higher,and pleural thickness was lower than those in the control group,differences were statistically significant(P＜0.01);and the total effective rate of 92.3% was higher than 75.5% in the control group,the difference was statistically significant(P＜0.01).ConclusionThe B ultrasound\|guided needle aspiration of the pleural effusion and intrapleural urokinase in the treatment of the parcel tuberculous pleural effusion is a safe,convenient,effective,economic method.
