The predictive effect of KDIGO criteria in the related kidney damage risk induced by contrast agents in severe patients

Objective: To investigate the predictive effects of the KDIGO criteria in the related kidney damage risk induced by contrast agents in severe patients. Methods: Four hundred and ninty patients with the history of intracranial artery interventional examination and therapy from May 2013 to January 2015 were selected.The diagnosis in the patients was evaluated using the KDIGO criteria and RIFLE criteria,and the difference between two diagnostic methods was compared. Results: Low permeability contrast agent was used,the evaluation of KDIGO and RIFLE diagnostic criteria showed that the acute kidney injury in 132 cases(26.94%) and 89 cases(18.16%) were identified,respectively.The average hospitalization time in 132 cases diagnosed by KDIGO criteria and 89 cases(death in 5 cases) diagnosed by RIFLE criteria were(10.15 ±2.30)and(9.23 ±1.95) days,respectively.The average hospitalization time in the patients detected by KDIGO criteria,but not by RIFLE criteria detection was(14.01±3.10) days.ROC curve anglysis shows that the area under the curve of the KDIGO standard is greater than the RIFLE standard and has a higher diagnosetic value. Conclusions: Compared with the RIFLE criteria,the KDIGO criteria can diagnose more patients with acute kidney injury more sensitively,which is beneficial to the diagnosis and treatment,and worthy of clinical application.
