AKI Acute kidney injury, BMI Body Mass Index, BUN Blood urea Nitrogen, COPD Chronic obstructive pulmonary disease, THA Total Hip Arthroplasty, TKA Total Knee Arthroplasty. P-values were determined using multivariate logistic regression of acute renal failure within 30 days postoperatively controlling for risk factors which were significant in univariate analyses. Total hip and knee arthroplasty patients without acute kidney injury within 30-days postoperatively were used as controls
