Signs & symptoms
A small renal infarct is often asymptomatic, and only evidence of its previous occurrence is detected on imaging at a later stage. When larger, patients typically present with acute flank pain and may have hematuria and proteinuria (blood and protein in urine).
Diagnosis
The first investigation of choice is usually a CT scan. If the clinical presentation is unclear, ultrasound may be performed.
Treatment
If the infarction is segmental, only supportive management is needed, and the cause of the infarction should be investigated. An attempt to revascularize the kidney can be made if the renal artery is completely blocked.
