Complications of antifibrinolysis therapy after prostatectomy.

As part of a trial to compare the effectiveness of various agents which have been claimed to reduce blood loss after prostatectomy, tranexamic acid (AMCA) was given pre-operatively and post-operatively to 6 patients having routine transurethral resections. Three of these developed indissoluble intravesical blood clots which persisted until they were evacuated surgically 5 to 17 days after cessation of AMCA therapy. AMCA cannot be recommended for routine use after prostatectomy.
