However, this procedure carries a significant risk of intraoperative and postoperative bleeding, often requiring blood transfusions. Tranexamic acid (TXA), an antifibrinolytic agent, has shown potential in reducing surgical blood loss. This study aims to evaluate the effect of intraoperative local administration of TXA on perioperative blood loss in patients undergoing open prostatectomy for BPH. <b>Methods:</b> In this double-blind randomized controlled trial, 140 patients with BPH were assigned to either a TXA group or control group. In the intervention group, 1 g of TXA was diluted in 100 mL of normal saline and injected into the prostatic fossa during surgery, followed by three additional postoperative doses. The primary outcome was total perioperative blood loss. Secondary outcomes included changes in hemoglobin, hematocrit, platelet count, transfusion requirement, and length of hospital stay. Baseline differences, including a significant age gap between the groups (mean age: TXA group 60.70 ± 7.44 years vs. control group 70.50 ± 6.68 years), were statistically adjusted during analysis. <b>Results:</b> Perioperative blood loss was significantly lower in the TXA group (116.65 ± 43.23 mL) compared to the control group (210.27 ± 87.94 mL, <i>p</i> value = 0.001). The mean hemoglobin drop was also significantly reduced in the TXA group at both 24 and 48 h postoperatively.

No major adverse events directly attributed to TXA were identified, although one patient in the TXA group developed a pulmonary embolism. <b>Conclusion:</b> Intraoperative local administration of TXA significantly reduces perioperative blood loss and the need for blood transfusion in patients undergoing open prostatectomy.

Although surgical reintervention is possible for large urinary tract injuries, a key component for healing smaller injuries is the ability to divert urine from the injury site to prevent urine-wound contact. This enables the injury to heal prior to reintervention and can eliminate the need for a secondary procedure, reducing the potential for complications. This type of urinary diversion is required by 140,000 patients in the United States annually, leading to the development of several devices to divert urine. The current standard of care includes minimally invasive procedures, such as placement of a catheter, double-J stent, or nephroureteral stent, but such measures often do not maintain sufficient dryness to enable wound healing. Based on a review of the literature, we have determined that successful devices need to prevent 100% of the anterograde urine flow, resist migration down the ureter because of peristalsis, and prevent urothelium growth over the device to promote wound healing without causing complications or necessitating reintervention. We also evaluated these devices according to the robustness of the study populations and designs in which they are reported. Some of the more successful devices include detachable, semicompliant balloons, platinum coils, and ureteral clips.

This study examines the safety and efficacy of CVP treatment for BPH patients with a hemorrhagic risk. <b>Patient and Methods:</b> A total of 93 BPH patients with lower urinary tract symptoms (LUTS) underwent CVP between February 2018 and September 2022.
