Description

Some reports have shown that thoracoscopic surgery for fibrinopurulent empyema with multiloculation and fibrinous and viscous fluid often leads to complete drainage. However, some patients cannot undergo surgical treatment because of their poor condition. Some papers have indicated that the intracavitary instillation of urokinase is a useful method for these cases. However, this has not been investigated sufficiently to become a standard method. In this paper, we report five patients who underwent the intracavitary instillation of urokinase for fibrinopurulent empyema. All patients showed empyema with multiloculated empyemic fluid and pleural thickening. Four of the five patients could achieve the relief of fluid accumulation after urokinase instillation (120,000 IU X 6-9 times). The other patient recovered after the instillation of urokinase followed by surgical treatment. The intracavitary instillation of urokinase was performed 1-16 days after the onset of empyema in the former 4 patients, and one month after in the latter one. All patients recovered without major complications. This procedure might be useful for the treatment of fibrinopurulent empyema in high-risk patients.
