 Participants will be randomized into one of two study groups: Group TXA: intravenous tranexamic acid: bolus of 10 mgkg thirty minutes before resection followed by infusion of 1 mgkgh intraoperatively and for 24 h postoperatively. Control Group C: an equal volume of saline. The study drug was prepared by an anesthesiologist not involved in the patient management and data collection. The anesthetic technique will be standardized. Serum hemoglobin was measured before and after surgery. The volume of the irrigation fluid, resected prostate weight and duration of resection were recorded.
