Objective:
To assess the efficacity and safety of using tranexamic acid (TXA) in the irrigation solution during transurethral resection of the prostate (TURP).
Patients And Methods:
A total of 50 patients undergoing TURP for benign prostatic hyperplasia were prospectively randomised in a controlled clinical trial and distributed into two groups. Group A received 0.1% TXA 1000 mg (10 mL) in 1 L of irrigation solution of sterile wash (glycine) during surgery, while Group B received 10 mL distilled water (placebo) in 1 L of irrigation solution of sterile wash (glycine) during surgery. At the end of surgery, a three-way catheter was inserted in the bladder. Group A received local 500 mg of TXA (5 mL), which was dissolved in 100 mL of normal saline solution, while Group B received distilled water (5 mL) dissolved in 100 mL of normal saline solution after which the catheter was clamped. The serum haemoglobin (Hb) concentration, haematocrit (HCT), blood loss volume, Hb concentration in the irrigation fluid, and bladder irrigation volumes were compared between the two groups at three time-points: preoperatively and at 4- and 24-h postoperatively. Coagulation function, complications, thromboembolic events, quality of endoscopic view, surgery duration, and hospital stay were also noted.
Results:
Group A had significantly lower blood loss intraoperatively, and at 4- and 24-h postoperatively compared to the control group (P < 0.05). The serum Hb concentration, HCT, Hb concentration in the irrigation fluid, and bladder irrigation volumes were significantly lower in the TXA group vs the control group (P < 0.001). The shortening of the surgery duration and improvement in the quality of the endoscopic view were significantly noted in the TXA group (P = 0.001). However, no thromboembolic events occurred in either group.
Conclusion:
The use of TXA in the irrigation fluid during TURP and injection into the bladder postoperatively can reduce blood loss and the need for blood transfusion without increasing the risk of thrombosis.
