ObjectivesTo determine whether short-term treatment of patients about to undergo transurethral resection of the prostate (TURP) with tranexamic acid (TXA) would be beneficial in reducing the associated blood loss.MethodsA prospective and randomized trial was conducted with 136 men requiring TURP for obstructive urinary symptoms. The treatment group received 2 g TXA three times daily on the day of, and first day after, the operation.ResultsShort-term TXA treatment significantly reduced the operative blood loss associated with TURP (128 mL versus 250 mL, P = 0.018), and this difference was not a result of the amount of tissue resected between the two groups (16 g versus 16 g, P = 0.415). In addition, TXA treatment reduced the amount of blood loss per gram of resected tissue (8 mL/g versus 13 mL/g, P = 0.020). Furthermore, the volume of irrigating fluid required (15 L versus 18 L, P = 0.004) and operating time (36 minutes versus 48 minutes, P = 0.001) were also reduced. However, TXA treatment did not influence the number of patients requiring a blood transfusion. Six patients in the treatment group (7.2%) and five in the control group (6.8%) required a transfusion (P = 0.709). Moreover, TXA treatment did not affect the duration of catheterization (1 day versus 1 day, P = 0.342) or hospitalization (3 days versus 3 days, P = 0.218).ConclusionsShort-term TXA treatment is effective in reducing the operative blood loss associated with TURP.
