Abstract
OBJECTIVES To conduct a systematic review of tranexamic acid (TXA) and the risk of renal failure from urinary clots in adult patients with hematuria. METHODS A systematic review of Medline, Embase, CENTRAL, www. CLINICAL TRIALS gov and Google Scholar were searched. Randomized control trials (RCTs) and observational studies that assessed the risk of renal failure with use of TXA among adults with hematuria were included. The primary outcome was renal failure due to urinary tract clots with TXA compared to no TXA (or placebo) or comparator. RESULTS We identified three RCTs (N=466 patients) and three retrospective cohort studies (N=220 patients), and a total of 342 patients that had hematuria and received TXA. The patient population of the six studies included medical and surgical patients, with two of the three RCTs comprised of patients undergoing percutaneous nephrolithotomy, and the third RCT comprised of patients undergoing transurethral resection of the prostate. Documentation of renal function before and after TXA administration was documented in only two studies (N= 28 patients), and neither identified worsening renal function in those exposed to TXA. CONCLUSIONS There are limited studies evaluating the risk of renal failure in patients with hematuria who were exposed to TXA, and the available data does not suggest an increased risk.
