Abstract
PURPOSE Analyze the impact of Tranexamic acid (TA) use after percutaneous nephrolithotomy (PNL) on blood loss and transfusion rate (TR), and secondary outcomes, complications rate and stone free rates (SFR), Operative time (OT) and length of hospital stay (LOS). MATERIALS AND METHODS Search made in the Medline (PubMed), Embase, and Central Cochrane for studies published up to August 2021. The study protocol was registered at PROSPERO (CRD42020182197). Eligibility criteria were defined based on PICOS. Articles included were those who assessed the effect of intravenous TA in patients submitted to PNL. Only randomized placebo-controlled trial which included patients with and without TA perioperatively. Results: A total of 1,151 patients were included in 7 studies. Six studies presented a lower blood TR for the TA group (P<0.00001). Four studies presented similar results in relation a lower stone free rate (SFR) (P=0.004), and similar results regarding overall complication rate for the control group (P=0.03). Regarding the 'major complication rate' (Clavien-Dindo ≥3), no difference was found (P=0.07). Four studies showed a higher mean OT for the control group (159 x 151 minutes, respectively, P=0.003). Six studies found a lower mean LOS in the TA group (4.0 x 3.5 days, respectively, P=0.03). CONCLUSIONS The benefit of TXA use in the setting of PCNL perioperative is clear. Our study showed favorable results to TXA use in relation to TR, SFR, complication rate, OT and LOS, but these results did not translate into a lower major complication rate. Further studies evaluating the complexity of the calculi and events unrelated to PCNL may help us to select which patients will benefit from the use of TXA.
