This study is about investigating the relationship of postoperative fluid balance, inflammation and acute kidney injury. This is a non-interventional study (no drug administration). The investigators will collect baseline demographic data, postoperative fluid balance status by Intake-output data, follow routine labs and collect 1 blood sample (0.5ml) with morning lab draws on day 1 and 5ml urine samples on day 1 and 2.
