Contrast-induced acute kidney injury (CI-AKI) is an important cause of acute renal injury. Several clinical trials using renal replacement therapy (RRT) for prevention of CI-AKI yielded conflicting results. We performed a meta-analysis to assess the efficacy of prophylactic RRT on CI-AKI. ⋯ RRT fails to reduce the incidence of CI-AKI in CKD stage 3 patients, but may be beneficial in patients with more advanced renal function. CRRT is more effective than hemodialysis for prevention of CI-AKI. RRT is effective in reducing the in-hospital mortality of CI-AKI patients.
