Significant values are in bold
AKI acute kidney injury, OR odds ratio, aOR adjusted odds ratio, CI confidence interval, SE standard error, β beta-coefficient; CKD chronic kidney disease, ESRD end stage renal disease
^aMultivariate analyses were adjusted for significant baseline characteristics, including age, race, income, insurance status, hospital location and teaching status, region, radical prostatectomy caseload, and all comorbidities
^bThe ESRD group was not included in the model of postoperative AKI and urinary complications
