View clinical trials related to Renal Resistive Index.
Filter by:AKI(Acute Kidney Injury) is a common complication after cardiac surgery which is associated with increased mortality and morbidity. The conventiional marker for detecting AKI is serum creatinine, however, which has many limits. RRI(Renal Resistive Index) is a non-invasive test measured by ultrasound and could be a useful tool to evaulate renal insult in the early phase. Early detection of renal insult and prevention of progression to AKI can contribute to reduing mortality and morbidity in cardiac surgical patients.
We aim from this study to investigate the role of renal resistance index (RRI) in evaluation of Acute kidney injury development and fluid administration in sepsis patients considering the change in RRI values over 7 days from admission as a predictor of AKI development
Renal resistive index (RRI) is calculated from ultrasonographic Doppler measurements of flow velocities in intraparenchymal renal arteries. Normal values are around 0.60, and 0.70 is considered the upper normal threshold in adults. Both preoperative and postoperative elevation of RRI has shown promise in early detection of AKI after cardiac surgery. Further, elevated RRI before coronary angiography is associated with an increased risk of cardiovascular complications up to 1 year after the procedure. The role of preoperative RRI in predicting long-term renal and cardiovascular complications after elective surgery is however not known. The aim of this study is to assess the role of preoperative RRI to predict the risk of persistent renal dysfunction as well as renal- and cardiovascular complications up to 5 years after surgery.
Purpose: The aim of this study was to assess the ability of early discrimination between transient and persistent Acute Kidney Injury (AKI) using the color Doppler Ultrasound derived Renal Resistive Index (RI) and semi-quantitative evaluation of intra-renal vascularization in septic patients in an Intensive Care Unit (ICU). Methods: Prospective observational cohort study with unselected, with 32 adult consecutive septic patients. Patients were divided into 3 groups: Group 1: patients without progression to AKI, Group 2: transient AKI, Group 3: persistent AKI.
An observational trial aiming to verify whether does any relationship exist between renal resistive index and postoperative outcome in major high risk surgery
