Official title
Novel Biomarkers to Predict Acute Kidney Injury and Chronic Kidney Disease After Radical Nephrectomy: an Exploratory Prospective Cohort Study
Overview
The incidence of acute kidney injury (AKI) after radical nephrectomy exceeds 40%. Currently, the KDIGO criteria are the recognized diagnostic standard for AKI. These criteria primarily use serum creatinine and urine output as key indicators, but both parameters have certain limitations, such as delayed response, insensitivity, and inaccuracy. This study aims to simultaneously monitor perioperative novel renal damaging, stressful, and functional biomarkers in patients undergoing radical nephrectomy, and to investigate their predictive value for AKI and postoperative 1-year chronic kidney disease (CKD).
Primary outcome measures
- The urinary [TIMP-2]×[IGFBP-7], urinary NGAL, urinary KIM-1, serum cystatin C and their combinations to predict postoperative AKI occurring within 7 days. [Time frame: Up to 7 days after surgery.]
Secondary outcome measures (3)
- The urinary [TIMP-2]×[IGFBP-7], urinary NGAL, urinary KIM-1, serum cystatin C and their combinations to predict new onset/worsening CKD occurring within 1 year after surgery. [Time frame: Up to 1 year after surgery]
- The urinary [TIMP-2]×[IGFBP-7], urinary NGAL, urinary KIM-1, serum cystatin C combined with clinically important risk factors to predict postoperative AKI occurring within 7 days after surgery. [Time frame: Up to 7 days after surgery.]
- The postoperative urinary [TIMP-2]×[IGFBP-7], urinary NGAL, urinary KIM-1, serum cystatin C combined with clinically important risk factors to predict postoperative the new onset/worsening CKD occurring within 1 year after surgery. [Time frame: Up to 1 year after surgery.]
