Description
Summary:Background:  Renal infarction is usually an underestimated disease due to its rare and non‐specific presentations; the renal survival of these patients is not well studied. The aim of the present analysis is to study the clinical features and outcome in patients who had documented renal infarction. Methods:  Twenty‐two patients (12 men and 10 women, mean age of 57.7 ± 3.44 years (28.4–83.3 years)) with image‐confirmed segmental renal infarction in the past 15 years were enrolled. All patients were followed up at outpatient department with a median of 4 years (1–14 years). Initial and follow‐up clinical characteristics and laboratory results were recorded. Results:  The most common underlying disease was cardiovascular disease. Renal infarction often presented with non‐specific symptoms, including flank pain (55%), vague abdominal pain (50%), nausea/vomiting (46%) and fever (27%). The levels of leucocytes, lactate dehydrogenase, blood urea nitrogen and serum creatinine were all elevated at admission. The early diagnosis group (12/22) had more obvious flank pain, nausea/vomiting (P
