Acute kidney injury (AKI) is reported in up to 30%1 of patients undergoing cardiac surgery and is a recognized independent predictor of both morbidity and mortality. To date, no preventive strategies have been shown in clinical trials to reduce the occurrence of cardiac surgery-associated AKI.

30% of patients undergoing cardiac surgery suffer from AKI
Leading to higher morbidity and mortality3
RenalGuard® demonstrated a 52% reduction in AKI vs. standard of care
- The KIDNEY study is a 220-patient (on-pump) randomized controlled study
- 110 patients in each arm (RenalGuard Therapy vs. standard of care).
- Study conducted at a leading hospital in the UK.
- The number needed to treat (NNT) with the RenalGuard system to prevent AKI was 9 patients.
