Acute renal infarction: A single-center experience

Abstract

Objective: The aim of this study is to evaluate the clinical characteristics and short- and midterm renal functions in patients with acute renal infarction.Methods: The medical records of the patients who were diagnosed with acute renal infarction by computed tomography in our clinic between 2012 and 2019 were retrospectively reviewed. Twenty-four patients who had follow-up data for at least 1 year were included in the study. Clinical, radiological, and laboratory findings of the patients at the time of admission and the results of serum creatinine level and glomerular filtration rate at first month and first year were recorded. Results: The mean age of the patients was 49.5 ± 20.7 years. In half of the cases, cardiac origin diseases were the underlying risk factor of acute renal infarction. Flank/abdominal pain was the most common presenting symptom. At admission, mean white blood cell count, serum lactate dehydrogenase, serum creatinine, and glomerular filtration rate values were 12 507 ± 6367/μL, 437.4 ± 261 U/L, 1.4 ± 1.9 mg/dL, and 85.3 ± 47.7 mL/min/1.73 m2, respectively. Chronic kidney disease developed in 7 patients. Conclusions: Acute renal infarction should be taken into consideration in patients with flank or abdominal pain and increased serum lactate dehydrogenase level. In addition, patients with acute renal infarction are at risk of developing chronic kidney disease.
