ABSTRACT
Background: Renal infarction is a rare disease in clinical practice, in most cases it
is triggered by predisposing thromboembolic factors, with atrial fibrillation being the
main risk factor, only a minority of cases is associated with small vessel vasculitis and
another large percentage is idiopathic. Semiologically it presents with severe, sudden
low back pain that simulates reno-ureteral colic; this clinical presentation obligates to
rule out urolithiasis, so the diagnosis is usually late and by exclusion. The diagnostic
study of choice is the contrast computed axial tomography of abdomen. The basis of
treatment is anticoagulation, mainly with coumarins.
Clinical cases: A 41-year-old male patient, without risk factors, previously healthy,
who debuted with sudden intense left lumbar pain, the diagnosis was made with
contrasted abdominal tomography and it was determined that the etiology of the renal
infarction was finally idiopathic after ruling out atrial fibrillation, thrombophilia and
vasculitis.
Conclusions: More studies are needed to provide guidelines in the treatment of
this idiopathic percentage of patients.
