In order to eliminate wasting vials of urokinase, 5000 U/ml aliquots were reconstituted and frozen. The urokinase remained effective for clearing thrombosed catheters for as long as 9 months. When catheters become occluded, patency can be restored by previously frozen urokinase.
为了避免浪费尿激酶瓶剂，将其以5000 U/ml的分装量进行复溶并冷冻。尿激酶在长达9个月的时间里仍能有效清除血栓形成的导管。当导管堵塞时，先前冷冻的尿激酶可恢复其通畅性。
