Background
- Low ED incidence, approximately 1 per 90 to 100, 000 visits a year
- Diagnosis frequently missed due to mimicking symptoms similar to other more frequent complaints such as pyelonephritis and nephrolithiasis
- Caused by interruption of blood supply to kidney
Major causes
- Cardioembolic disease
- Renal artery injury
- Hypercoagulable state
- Dissection
- Vasculitis
Clinical Features
- Flank pain
- Nausea, vomiting
- Sudden onset
Differential Diagnosis
- Nephrolithiasis
- Pyelonephritis
- Mesenteric ischemia
- Lower lobe pneumonia
Evaluation
Laboratory
- CBC with differential, CMP, LDH, urinalysis, urine culture
- EKG- to evaluate for arrhythmia
Imaging:[1]
- CT with IV contrast (preferred study)
- Renal ultrasound - less senstive
- MRI with gadolinium (contraindicated with severe renal impairment due to risk of nephrogenic systemic fibrosis)
- Radioisotope scan - not commonly used
Management
Disposition
