Safety and efficacy of intravenous tranexamic acid in endoscopic transurethral resections in urology: Prospective randomized trial
Endoscopic urological procedures (transurethral resection of the prostate TURP/transurethral resection of bladder tumor TURBT) are not without risk of significant bleeding. This risk is due to the vascular nature of the tissues and their high levels of fibrinolytic enzymes in the tissues and urine....

Summary: | Endoscopic urological procedures (transurethral resection of the prostate TURP/transurethral resection of bladder tumor TURBT) are not without risk of significant bleeding. This risk is due to the vascular nature of the tissues and their high levels of fibrinolytic enzymes in the tissues and urine. This study was conducted to evaluate the safety and efficacy of the antifibrinolytic agent tranexamic acid (TXA) in reducing blood loss in patients undergoing TURP/TURBT and transfusion requirement.
This study was a prospective, randomized, double-blind, placebo controlled clinical trial. One hundred and thirty-one patients of ASA physical status I or II, undergoing TURP (60 patients) or TURBT (71 patients) were randomly allocated to receive IV TXA: bolus of 10mg/kg at the induction of anesthesia followed by infusion of 1mg/kg/h intraoperatively and for 24h postoperatively or an equal volume of saline (control group). Blood loss was evaluated in terms of reduction in the serum hemoglobin level (delta Hb=Hb H24-Hb H0).
There was no difference between two groups in terms of transfusion requirements and episodes of retention. TXA did not significantly reduce mean blood loss compared with placebo during TURP (1.37±0.69 vs. 1.72±1.23g/dL respectively, P=0.256) or TURBT (1.15±0.95 vs. 1.07±0.88g/dL; P=0.532). No thrombotic complications were noted in any patient.
Tranexamic acid did not reduce transfusion requirements or perioperative blood loss in transurethral resection of the prostate or bladder tumor.
