Abstract
|
|
|
Objective: Acute renal infarction is a rare and easily misdiagnosed disease. Scarce research has been conducted on the predictive factors and prognosis of acute renal infarction due to its rarity. In this study, we analyzed the clinical and laboratory findings of a patient diagnosed with renal infarction to predict clinical outcomes.
Methods: In this retrospective clinical study, we collected and analyzed the medical records data of 61 acute renal infarction patients diagnosed in the emergency department (ED) of Konkuk University Hospital, Seoul, South Korea from January 2007 to December 2020.
Results: Lactate dehydrogenase (LDH; 93.3%, 28 of 30 patients) and D-dimer (77.8%, 28 of 36 patients) levels of the acute renal infarction patients were higher than the normal. Proteinuria was found in 26 of 47 patients. The only significant prognostic factor for the occurrence of acute kidney injury (AKI) in acute renal infarction is the ratio of the infarction volume to the total renal volume. Age, occurrence of AKI, and proteinuria were correlated with the progression of chronic kidney disease (CKD).
Conclusion: The ratio of the infarction volume to the total renal correlated with occurance of AKI. Age, AKI, and proteinuria were correlated with the progression of CKD.
