Intraprostatic Injection of Tranexamic Acid Decrease Blood Loss During Monopolar Transurethral Resection of the Prostate: A Randomized Controlled Clinical Trial.

OBJECTIVE

To assess the role of intraprostatic injection of tranexamic acid (TXA) in reducing blood loss during transurethral resection of the prostate (TURP).

METHODS

We conducted a randomized, controlled, double-blind trial involving 60 patients with benign prostatic hyperplasia aged 50-85years, undergoing monopolar TURP. Patients' prostatic weights ranged from 50 to 80 g. They were divided equally into two groups: group I received an intraprostatic injection of 1 g of TXA (Cyklokapron) dissolved in 50 mL of 0.9 % saline at multiple sites, while group II (control) received a 60 mL saline injection. Comprehensive clinical assessments and standard laboratory tests, including screenings for TXA hypersensitivity, were performed for all patients.

RESULTS

Group I exhibited significantly lower intraoperative blood loss and hemoglobin concentration in irrigation fluid immediately postsurgery and at the 6-hour postoperative mark compared to group II (P < .05). Coagulation parameters-activated partial thromboplastin time, prothrombin time, fibrinogen level, and thrombin clotting time-showed no significant differences between the groups preoperatively or at 6 and 24 hours postoperatively. No thromboembolic events or other complications were reported in either group.

CONCLUSION

The intraprostatic injection of TXA during monopolar TURP is safe, with minimal adverse effects, and effectively reduces blood loss.

REGISTRATION

The study was registered on ClinicalTrials.gov No (ID: NCT05913466).
