ABSTRACT
Introduction:
We performed a systematic review and meta-analysis of the current literature to assess the efficacy and safety of tranexamic acid (TXA) in the management of postoperative bleeding after percutaneous nephrolithotomy (PCNL).Methods:
A systematic literature review was performed in March 2021. Two reviewers independently screened, identified, and evaluated comparative studies assessing the effectiveness of TXA in preventing bleeding after PCNL when compared with placebo or no intervention. The incidence of transfusion, complete stone clearance, and complications were extracted among TXA and control groups to generate the risk ratio (RR) and corresponding 95% confidence interval (CI). Blood loss, hemoglobin (Hb) drop, length of hospital stays, and operative (OR) time were analyzed using standard mean difference (SMD) with corresponding 95% CI. Effect estimates were pooled using the inverse-variance approach with a random-effect model.Results:
A total of 11 studies (8 randomized controlled trial, 1 prospective cohort, and 2 retrospective cohort studies; total 1842 patients) of low-to-moderate-quality were included in the meta-analysis. Overall pooled effect estimates demonstrated a decreased transfusion rate (RR 0.36; 95% CI 0.25 to 0.51), blood loss (SMD -0.74; 95% CI -1.14 to -0.34), and Hb drop (SMD -0.95; 95% CI -1.51 to -0.39) among patients in the TXA group when compared with those in the control. The number needed to treat was 11 to prevent one transfusion. Patients who received TXA also had improved stone clearance (RR 1.08; 95% CI 1.02 to 1.14), lower minor (RR 0.72; 95% CI 0.58 to 0.89) and major (RR 0.38; 95% CI 0.21 to 0.69) complications, shorter hospital stays (SMD -0.52; 95% CI -1.01 to -0.04) and decreased OR time (SMD -0.89; 95% CI -1.46 to -0.31).Conclusions:
TXA can effectively reduce postoperative bleeding after PCNL. Future studies should identify a subset of patients who may benefit from preoperative TXA administration for PCNL.Palavras-chave
