They most commonly present in the form of acute kidney injury (AKI). The etiological factors of AKI include hemodynamic alterations, hemolysis and pigment nephropathy, inflammatory response and cytokine storm, ischemia-reperfusion injury, use of nephrotoxic agents, patient-related risk factors (advanced age, diabetes mellitus, preoperative renal insufficiency, congestive heart failure, hypertension, anemia), duration of surgery, and postoperative complications such as low cardiac output syndrome, sepsis, bleeding and reoperation, hypoalbuminemia, and fluid imbalance.\n\nPrevious studies have demonstrated several mechanisms through which elevated HbA1c levels may contribute to acute renal injury, including glomerular damage and hyperfiltration, endothelial dysfunction and microvascular injury, tubular damage, accumulation of glycation products and advanced glycation end products (AGEs), structural changes in blood vessels, and metabolic and systemic factors.\n\nThe evaluation of acute renal failure relies on fundamental scoring systems, biomarkers, and imaging modalities. Among the scoring systems, the most current and widely used is the KDIGO (Kidney Disease: Improving Global Outcomes) classification. According to the KDIGO definition, the diagnosis of AKI can be established when at least one of the following three criteria is met: an increase in serum creatinine of ≥0.3 mg\u002FdL within 48 hours, an increase in serum creatinine to ≥1.5 times baseline within 7 days, or a urine output of \\\u003C0.5 mL\u002Fkg\u002Fhour for more than 6 hours. AKI staging is performed based on these parameters.\n\nImaging modalities used in the assessment of renal function include renal ultrasonography (US), Doppler ultrasonography with measurement of the renal resistive index (RRI), renal MRI\u002FMR angiography, and renal computed tomography (particularly CT angiography). RRI is a non-invasive, bedside-applicable method that provides direct information about renal vascular resistance by evaluating renal arterial flow patterns.\n\nIn our clinic, the rationale of the present study is to measure preoperative HbA1c and Doppler-derived RRI values in patients undergoing isolated coronary artery bypass surgery, and to evaluate their relationship with postoperative KDIGO classification and Doppler RRI values in order to gain insight into the development of AKI.",[58,59,60,28],"Acute Kidney Injuries","Hemoglobin A1c Protein, Human","Coronary Bypass Graft Surgery",[62,63,64,65],"acute kidney injuries","hemoglobin A1c protein","coronary bypass graft surgery","renal resistive index","RECRUITING","2026-02-25",{"date":69,"type":38},"2026-03-03",{"date":71,"type":38},"2026-01-20",{"date":73,"type":21},"2026-08-30",{"name":75,"class":45},"Osman Sila Aydin",1,{"id":78,"slug":79,"hasResults":11,"nctId":80,"briefTitle":81,"officialTitle":81,"acronym":4,"eligibilityCriteria":82,"healthyVolunteers":11,"sex":17,"minAge":83,"maxAge":84,"enrollmentInfo":85,"targetDuration":4,"studyType":22,"phases":4,"briefSummary":87,"conditions":88,"keywords":4,"overallStatus":34,"whyStopped":4,"lastUpdateSubmitDate":89,"lastUpdatePostDateStruct":90,"startDateStruct":92,"completionDateStruct":94,"leadSponsor":96,"locationsCount":4},"100551790","association-between-renal-resistive-indexrri-and-akiacute-kidney-injury-in-cardiac-surgery-patients-with-cardiopulmonary-bypass-cpb-100551790","NCT06464666","Association Between Renal Resistive Index(RRI) and AKI(Acute Kidney Injury) in Cardiac Surgery Patients With Cardiopulmonary Bypass (CPB)","Inclusion Criteria:\n\n* Aged 19 years and older scheduled for cardiac surgery using CPB\n\nExclusion Criteria:\n\n* Emergency opeartion, pre-operative shock status requiring vasopressor or inotropics, s\u002Fp kidney transplant patients, CKD stage 4 and 5 patients, patients who have renal artery stenosis or history of renal artery stent implantation, patients who have ascites with Child-Pugh classification B or C, In case of CPB weaning failure, In case of poor lung function and PaO2 or PaCO2 cannot be maintained within normal range.","19 Years","90 Years",{"count":86,"type":21},250,"AKI(Acute Kidney Injury) is a common complication after cardiac surgery which is associated with increased mortality and morbidity.
