ABSTRACT

Introduction: the impact of acute kidney injury is 13-50%, reporting a mortality rate of 59% in critically ill patients compared to other associated pathologies. Therefore, new accessible, reproducible and cost-effective renal function assessment tools are needed to detect this entity early. Objective: to demonstrate that the renal resistance index (RRI) is useful as an early predictor of acute kidney injury in patients with rhabdomyolysis. Material and methods: observational, prospective and analytical study. Critically ill patients with a diagnosis of rhabdomyolysis were enrolled and underwent RRI, urinary index and creatinine measurements at admission and 24 hours. Results: forty-two patients were analyzed: 37 (88.1%) men and five (11.9%) women. Traumatic etiology was the most frequent 71.4%. There was a significant association between RRI at admission (p = 0.0089), RRI at 24 hours (p = 0.026); values at admission showed an area under the curve (AUC) of 0.957 (p = 0.001); cut-off point of 0.64; with a sensitivity of 92.85% and specificity of 10.71%. Conclusion: in this group of patients, the results show that the renal resistance index is useful as an early predictor of acute kidney injury in patients with rhabdomyolysis.
