Ten patients developed acute kidney injury in the postoperative period. The use of angiotensin-converting enzyme inhibitors and postoperative diuresis were significantly associated variables (p=0.039 and 0.034, respectively). The diuresis cutoff value to foretell non-progression to acute kidney injury was 0.5 mL\/kg\/h, with an accuracy of 88%, sensitivity of 100%, specificity of 77.78%, positive predictive value of 86.67%, and negative predictive value of 100%.<\/p>\n<h2><strong>Conclusions<\/strong><\/h2>\n<p>In elderly patients undergoing elective colorectal surgery for oncological treatment, the incidence of acute kidney injury was high.<\/p>","protected":false},"excerpt":{"rendered":"<p>Background<br \/>\nThe increase in life expectancy and the development of comorbidities bring a higher rate of complications and mortality in the postoperative period of surgical procedures in general.
