Urinary Tract Calculi VI: Surgical Management

1.0K
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary
This summary is machine-generated.

Prophylactic tranexamic acid (TXA) did not reduce red blood cell transfusions in patients undergoing open radical cystectomy for bladder cancer. Routine use of TXA in this patient population is not recommended based on trial findings.

Area of Science:

  • Urology
  • Surgical Oncology
  • Anesthesiology

Background:

  • Open radical cystectomy for bladder cancer carries a high risk of red blood cell (RBC) transfusion.
  • Prophylactic tranexamic acid (TXA) is known to reduce blood loss in other surgical settings.
  • The potential benefit of TXA in radical cystectomy warranted investigation.

Purpose of the Study:

  • To evaluate the efficacy of prophylactic tranexamic acid (TXA) in reducing RBC transfusions up to 30 days after open radical cystectomy.
  • To assess the impact of TXA on blood loss and other perioperative outcomes in patients undergoing radical cystectomy.

Main Methods:

  • The Tranexamic Acid During Cystectomy Trial (TACT) was a multicenter, double-blind, placebo-controlled, randomized clinical trial.
  • 353 patients undergoing planned open radical cystectomy were randomized to receive either intravenous TXA or a matching placebo.
  • The primary outcome was the receipt of RBC transfusion within 30 days post-surgery.

Main Results:

  • RBC transfusion occurred in 37.0% of patients receiving TXA versus 37.4% receiving placebo (relative risk, 0.99; 95% CI, 0.83-1.18).
  • No significant differences were observed in secondary outcomes, including mean RBC units transfused, estimated blood loss, intraoperative transfusion rates, or venous thromboembolic events.
  • Adverse events were similar between the TXA and placebo groups.

Conclusions:

  • Prophylactic tranexamic acid (TXA) administration did not significantly reduce red blood cell transfusions in patients undergoing open radical cystectomy for bladder cancer.
  • Based on the TACT trial results, routine use of TXA in this surgical context is not recommended.
  • Further research may explore alternative strategies for blood loss management in radical cystectomy.
